White, foamy sweat is a by-product of over-strenuous work or being exercised in excessive heat. White, foamy sweat is a by-product of over-strenuous work or being exercised in excessive heat. White sweat contains proteins, which take too long to dissipate to make an effective method of cooling the horse’s body.
- Why is horse sweat white? A healthy horse sweats in order to lower its body temperature. If there is more heat in the area than a horse can take, or if the horse works out too much, there is a chance that your pet will start sweating too much and get dehydrated.
Is soap made from horse sweat?
Latherin is the substance in horse sweat that creates the foam that you see on your horse. Technical: Latherin is a protein that’s also a non glycosylated surfactant. Translated: Latherin is a protein that acts like soap. It’s slippery, and 37% of latherin contains ingredients that repel water.
What is in horses sweat?
The sweat glands begin to pump out sweat. It’s mostly water, but it also contains dissolved minerals called electrolytes. A horse’s sweat has a higher concentration of electrolytes than yours. As the sweat evaporates, it carries heat away from the skin, reducing the horse’s body temperature.
Is sweating bad for a horse?
When horses sweat, they can lose a lot of important electrolytes that are integral for their health and hydration. Excessive sweating caused by dehydration is one of the greatest risks to your horse. When humans sweat, they lose mainly water and the water loss causes low numbers of electrolytes and thirst as a result.
Why do horses get lathered up?
Hot work: a special protein in horse sweat called latherin acts by wetting the hairs to facilitate water flow for evaporation. Ever wondered why your horse lathers up when it sweats? It’s all because of a special protein in the sweat appropriately named latherin.
Why do horses foam at the mouth?
Horses produce a lot of saliva when eating or drinking. The saliva helps their food to digest, but it can also result in foam around the mouth. This foam is normal and harmless; a sign that your horse is functioning properly.
How do you make horse soap?
DIY Natural Horse Shampoo Recipe
- 1 cup Dr. Bronners Liquid Soap.
- 1 tsp. Jojoba Oil.
- 1 tsp. Fractionated Coconut Oil.
- 2 tsp. Vegetable Glycerin.
- 2 tsp. Witch Hazel.
- Essential Oils (optional)
Why is horse sweating for no reason?
Like humans, horses sweat to dissipate heat. Horses sweat excessively during very hot conditions, and when they have been exercised intensely, especially when they are unfit. Horses also sweat when they have a high fever or are in pain or distress.
How do you treat sweaty horses?
After training make sure your horse has a good cooling down. Walk 5 to 10 minutes, so the muscles won’t get sore too. If your horse is slightly damp, brushing him after the training will do. If he’s sweaty, you can put an exercise rug to help him evaporate the sweat.
Does beer help horses sweat?
Guinness stout beer is often recommended as an aid to help horses with anhidrosis, but beer for horses goes beyond that. On the backside of many race tracks across the country and in the barns of many well known show jumpers, Guinness stout beer is a regular part of supplementing a horse’s diet.
How do you know if your horse is sweating?
After a workout, it’s normal for a horse to sweat profusely, but a horse who sweats even when standing still may need some help staying cool and will appreciate being hosed down. Sweat appears on the head, flanks and top of the rump when a horse is extremely hot and may be at risk of heat stress.
What is Horner’s syndrome horse?
Horner’s syndrome in horses is characterised by upper palpebral ptosis, hyperthermia and unilateral sudoresis of the face and variable regions of the neck and trunk, whereas enophthalmos, third eyelid protrusion and miosis are less common signs.
Do horses sweat when stressed?
Trembling, Sweating and Elevated Pulse During a stressful situation, a horse may exhibit many of the same physical signs that a person does when they are stressed. The horse’s heart rate and breathing increase and they may begin to sweat.
What does the word lathering mean?
1a: a foam or froth formed when a detergent (such as soap) is agitated in water. b: foam or froth from profuse sweating (as on a horse) 2: an agitated or overwrought state: dither worked himself into a lather. lather. verb.
What is Latherin?
Latherin is a highly surface-active allergen protein found in the sweat and saliva of horses and other equids. It is a member of the PLUNC family of proteins abundant in the oral cavity and saliva of mammals, one of which has also been shown to be a surfactant and capable of disrupting microbial biofilms.
What does horse sweat smell like?
Performance horses in training are worked hard enough to sweat almost daily, and that smell carries a hint of ammonia, along with everything else on the horse’s skin.
Why is my horse ‘foamy’ when he sweats?
Pro Equine Grooms talks on a widespread misconception regarding horses: “a foamy horse does not necessarily indicate that the horse has been overworked.” When your horse sweats, the foam on his brow is the consequence of the components in his sweat “” and it’s a pretty fancy horse adaption. So, let’s speak about latherin for a minute. Latherin is a chemical found in horse sweat that contributes to the formation of the foam that you notice on your horse’s back. Technical: Latherin is a protein that also happens to be a non-glycosylated surfactant (i.e., it does not dissolve in water).
To put it another way, latherin is a protein that has the same properties as soap.
Latherin may also be found in your horse’s saliva, and it has been hypothesized that saliva was the initial source of latherin in the horse.
Theoretically, latherin became a component of horse sweat as a way to aid evaporative cooling in horses with a hairy coat throughout time.
- However, his hair coat (even in the heat) acts as a physical barrier, preventing the sweat from escaping.
- And, yeah, I did just typelickify the sentence.
- The same way that your sponge foams up when you begin to wash the dishes, the same is true with your horse when you begin to ride.
- In situations where there is friction, you will most likely perceive it more.
- It is not an indication that your horse has been overworked, once again.
- If you have never seen it on your horse before, don’t be alarmed.
- A horse with anhidrosis or partial anhidrosis, on the other hand, does not sweat at all, or just partially sweats, and this is a condition that can be fatal.
Balanced Equine – Why Do Horses Foam?
Some horses become coated in white foam when they are exercised, whereas others do not. Because horse sweat includes a high concentration of a protein known as ‘latherin,’ it is considered to be uncommon. This protein functions as a detergent, assisting in the distribution of perspiration over the horse’s body, allowing the horse to be more effectively cooled.
It is perfectly normal and does not suggest a nutritional shortage or an excess of a nutrient in one’s food intake. Some horses froth more than others, and the quantity of foaming varies depending on the following factors:
- The horse’s fitness (in general, unfit animals foam more, whereas horses who have been worked hard and are regularly sweating froth less)
- Timing (since the protein concentration is maximum in the first first sweat, horses frequently froth for a brief period of time before stopping)
- The state of the horse’s coat (shampoos, conditioners, brushing, trimming, and other grooming practices can all have an impact on how much foam the horse produces)
To summarize, everything is totally normal. It does give a horse a heated and disturbed appearance, but it is not a problem that has to be addressed. In contrast, horses that compete or are trained on a regular basis, such as endurance horses, do not tend to foam much since they are constantly sweating and have short coats. They have a higher likelihood of being washed on a regular basis. Saliva includes a trace amount of latherin, and it has been hypothesized that this substance is there to aid in the mastication of huge amounts of dry food.

An excellent description of the role played by latherin in the mouth may be found in the following blog post: Everything You Need to Know About Foam
Just in case anyone was wondering, here’s the scoop on how horses sweat and why it’s so critical to manage their temps and hydration.
Sweat will froth as a result of friction foaming up the latherin that is already present in the body fluid. NOTHING indicates that the horse is overworked – it just indicates that latherin is carrying out its duties.
Horses, like humans, sweat as a response to heating up.
- Efforts to cool the body through evaporation result in the production of sweat. Isn’t it clear that this is rational and straightforward? Yes, unless you introduce some humidity into the atmosphere. The presence of humidity produces an atmosphere in which sweat has nowhere to dissipate since there is already an excessive amount of moisture in the air. This occurs when the humidity is around 75% or when the temperature plus humidity is greater than 140 degrees. It’s the same factors that cause your own hairstyle to get permanently damaged, although it’s a little more serious in the case of horses.
When these conditions are met, you have the potential for giant problems.Your horse will still be hot, so he will still sweat.
- This will result in his losing even more fluids and electrolytes, and he will be on the path to dehydration. As he loses fluids, his body will signal to him to “stop losing fluids” by constricting his blood vessels.
- His fluid and electrolyte losses will increase, putting him on the path to dehydration faster than before. While losing fluids, his body will tell him to “stop losing fluids” by constricting his blood vessels.
This implies that he will lose more fluids and electrolytes, and he will be on the path to dehydration. While losing fluids, his body will signal him to “stop losing fluids” by constricting his blood vessels.
Now let’s add electrolytes into the mix.Electrolytes are salts that help control muscle and nerve function.
- This indicates that their electrolyte balance has an impact on their heart, muscles, gastrointestinal system, and brain. Electrolytes are lost as a result of perspiration. Excessive electrolyte loss may even be seen and smelled since it results in the formation of a foam that has a pleasant fragrance to it due to the presence of latherin in the sweat.
- Foam is commonly found between the horse’s hind legs or where the reins rest on the horse’s neck. The foaming action is caused by the friction. More information about electrolytes may be found in this article.
- *** A horse’s dripping perspiration does not necessarily indicate that the animal has been overworked. It indicates that your horse is sweating and that there is tension between the two of you. Your horse is losing electrolytes as a result of the sweating. ****
Horses are also a bit unique in that their sweat glands love to leak out sodium and chloride (Na+ and Cl-), more so than humans or other animals.
- During exercise, they can also lose around 4 liters of water each hour (depending on the length, humidity, amount of exertion, and other factors)
- When you consider that the average horse consumes 10 to 20 gallons of water each day, this is a huge amount of water.
- The waste of water is enormous when you consider that the average horse consumes 10 to 20 gallons each day.
However, since horses lose so much salt through their sweat, their salt concentrations in the blood can actually decrease, and their brains will not get the signal to drink.
- The other mechanism that communicates thirst is a decrease in blood volume, which can reach hazardous levels before signaling the horse to drink.
- Your horse may waste important salt and water before he receives the cue to drink in either case.
So – when your horse sweats, you have two things to worry about – water and electrolytes.
- Your horse may waste important salt and water before he receives the cue to drink in either scenario.
- An electrolyte manufacturer’s favorite thing to do is to include sugar, which I avoid like the plague and instead choose a sugar-free version of
- If you are confused about the brand of electrolyte you are using, carefully read the label. Any sugar that ends in -ose, such as dextrose, is considered to be a sugar.
- And remember to give your horse something to drink after an exercise! The sooner you can get started, the better. It is completely fine and even advised to allow your horse to rehydrate after he has sweated.
During exercise, your horse’s hind legs can produce a significant amount of perspiration, which can trickle down the horse’s belly. In the following few sections, we’ll talk about replenishing electrolytes and water lost during exercise, as well as cooling off afterward! My favorite electrolytes are both reasonably priced and sugar-free. You may get them from this location.

Why do horses foam when they sweat? And how Foam is Produced
When a horse is exercising, especially on a hot summer day, it is normal to observe foam forming on his back and sides. In this essay, we shall discuss the reasons behind the appearance of this foam. Horses produce foam when they sweat due to the presence of latherin, a soap-like chemical. Latherin aids in the distribution of perspiration throughout the surface of the coat, allowing for the evaporation of sweat to occur for the purpose of heat loss. When friction happens, latherin creates foam in the same way as soap does: Tack rubbing against the coat or bodily parts rubbing against one other, such as the inner thighs, are examples of rubbing.
Explaining why sweat forms foam, the dangers of over- or undersweating, and why it is necessary to clean the horse’s coat after sweating are all covered in the next section of this article.
How is Foam Produced in the Sweat?
Horses sweat to maintain their body temperature in the same way that we humans do. However, because they have a thick waterproof layer, they would ordinarily be unable to facilitate the quick passage of perspiration from the skin to the surface of the hair, which is required for evaporative cooling to occur. As a result, they have developed a protein known as latherin, which is found in high amounts in their sweat. Equids are the only animals that have this protein.
Latherin Increases The Spreading Of Sweat
In order to boost the spreading and wetting qualities of sweat, latherin is added to the mix. This aids in the circulation of perspiration away from the epidermis and toward the surface of the scalp. Once the sweat reaches the surface and comes into touch with air, the water in it might evaporate, transporting the heat away from the body and causing it to cool down. This protein in sweat is not required by humans since we do not have a thick covering of waterproof hair on our skin, as is the case with most animals.
As a result, it is possible that they have evolved to use latherin as a means of swiftly and effectively dissipating heat.
Latherin is like Soap
As a surfactant (like soap), latherin is useful. By comparing latherin to soap, you will be able to comprehend why it is used as a spreading agent after viewing this video.
But what about the foam?
Latherin, on the other hand, acts in the same manner as soap does. You will notice that the water with soap becomes frothy as you rub your hands together to wash your hands. The same may be said about perspiration, which will turn frothy when it is rubbed:
- Tack rubbing on the coat (for example, the reins on the neck)
- Body parts rubbing together (for example, the buttocks)
- Tack rubbing against the saddle.
foam is a side effect of latherin when rubbing occurs
When you rub your armpits, the sweat will become agitated and air bubbles will form inside of it. The latherin then helps to keep these air bubbles stable. The latherin molecules wrap the air bubbles and allow them to remain in the sweat for an extended period of time without bursting. When the horse is sweating, the foam we see is made up of a large number of these air bubbles clumped together. It is thought that latherin originated in the saliva of horses, which explains why they froth at the mouth, and that it was subsequently evolved to aid in the thermoregulation action of sweating animals.
Foam can be an indicator of how much sweat was lost
Some German researchers discovered that the pattern of perspiration on the horse’s body corresponds to the amount of sweat shed by the animal.
|Pattern of sweat||Amount of lost sweat|
|– The area under the saddle and throat are wet– Small foam areas at the corners of the saddle||1 to 1.3 gallons / 4 to 5 liters|
|– The flank, and areas under the saddle and girth are wet– Foam on the bridle and noseband||1.8 to 2.3 gallons/ 7 to 9 liters|
|– Throat and flanks are wet, and areas above eyes are moist with dark wrinkles– Foam between the limbs||2 to 3 gallons/ 9 to 12 liters|
|– If sweat is dripping above the eyes and under the belly||3 to 4.7 gallons/ 12 to 18 liters|

Why you need to clean the sweat from the horse’s coat
In order to preserve the horse’s skin and hair in excellent condition, all perspiration must be removed from the horse’s body as soon as possible since a buildup of sweat can harm the hair:
- When heat is trapped beneath the mane, it is possible to experience excessive perspiration. It is important to remember that if perspiration is not eliminated, it will remain on the skin for a lengthy period of time and be absorbed by the epidermal layer, eventually reaching the hair follicles. The moisture will cause the hair follicle to weaken, resulting in the hair falling out gradually. The buildup of dried perspiration and filth on the horse’s skin might irritate it and cause it to lose its hair. As a result of their dislike to being cleaned in these places, this is typically visible on the horse’s face and ears.
In cases when the heat is retained behind the mane, excessive perspiration might develop. As long as the sweat is not removed from the skin, it will remain in the skin’s epidermal layer for a long time and be absorbed there, eventually reaching the hair follicles. Water will cause the hair follicle to soften, resulting in the hair falling out in the long run. The buildup of dried perspiration and grime on the horse’s skin might irritate it and cause him to lose his coat of hair. As a result of their dislike to being cleaned in certain places, this is usually noticed on the horse’s face and ears;
Grooming tools to remove sweat
I receive a compensation if you make a purchase using the links provided below that connect to items on Amazon. There is no additional cost to you if you use my affiliate links. My recommendations for grooming equipment that are effective in removing perspiration are as follows: To dislodge filth and perspiration that has become adhered to the horse’s coat, use a rubber curry brush. Wahl Professional Animal Equine Grooming Rubber Curry Horse Brush, Black, for Grooming Animals and Equines (858712) Body brush for horses to remove dirt and perspiration that has been loosen by the curry comb before using the curry comb itself.
A mane and tail brush is used to detangle hair that has been tangled in perspiration and filth, among other things.
Replenishing the electrolytes lost when sweating
It is believed that horses’ sweat has a high concentration of electrolytes. Electrolytes include minerals such as potassium, magnesium, sodium, chloride, bicarbonate and phosphate that are found in high concentration in horse’s sweat. Electrolytes are essential for a variety of biological activities, including muscular function and the maintenance of a regular heartbeat. They also aid in the prevention of dehydration in the horse by transporting water to the cells, as well as the enhancement of nutritional absorption.
As a result, it is critical to restore electrolytes that have been lost.
In most cases a the horses diet is enough
It is necessary to restore electrolytes lost when the horse sweats in order to prevent dehydration. However, sodium and chloride may need to be supplemented with a salt block because they are found in high concentrations in most horses’ diet. Sofood and a salt block will be sufficient to replenish the minerals that have been depleted.
When an electrolyte supplement is needed
Nevertheless, if the horse excretes excessive amounts of sweat over an extended period of time without the opportunity to replace these critical minerals, they may become depleted, and the physiological processes that they regulate may be interrupted. In these situations, the horse should be given an electrolyte supplement to immediately restore the nutrients that have been lost.
What if the horse does not sweat?
In order for a horse to cool his body when it becomes hot, he must be able to sweat. Horses are in risk when they are unable to sweat because they have no method of dissipating the heat that builds up in their bodies.
As a result, the temperature can rise to dangerous levels, placing him at risk of heatstroke. Anhidrosis is the medical term for this illness, which need specialized care and veterinary intervention.
How to detect anhidrosis
You will be able to recognize this ailment if you see the following symptoms in the horse:
- After strenuous labor, does not sweat or sweats only a little
- Breathes quicker and more heavily than would be anticipated
- Is hesitant to work and becomes weary more quickly than would be expected
If you detect any of these indicators, you should contact your veterinarian immediately to have the horse diagnosed. He may do a “sweat test” on the horse to determine whether or not it has anhidrosis.
Avoid Overheating a Horse with Anhidrosis
If anhidrosis is verified, you must take precautions to avoid creating situations that might cause the horse to overheat, such as:
- It is best to exercise him during a time of day when the temperature is lower
- After exercising, shower him to aid in the release of heat
- And keep him in a cool atmosphere.
- Several proteins found in the horse’s sweat, including latherin, are responsible for the foaming. The foam will only emerge when there is friction
- Otherwise, it will not appear. The presence of latherin in horses may be a contributing factor to human allergies to horses. In addition to proteins, such as latherin, the horse’s sweat contains electrolytes, which include minerals such as potassium, magnesium, sodium, chloride, bicarbonate, and phosphate
- Electrolytes are essential for the horse’s health. If a horse sweats excessively, he will lose electrolytes, which are essential to certain physiological processes, and these processes may be jeopardized if the electrolytes are not supplied. If a horse does not sweat, he is unable to release his heat and is at risk of suffering from heatstroke unless you assist him in cooling his body. Because perspiration can irritate the horse’s skin and cause hair loss, it is important to remove it from the horse.
Sweating is natural and necessary for a horse’s health, and the correct quantity is required. In contrast, if they are sweating excessively for the circumstances, this is not considered natural. Worse worse, when the circumstance calls for it, there is no sweating at all. Horse owners must understand the difference between a good sweat and an unhealthy sweat in order to keep their equine friends hydrated and limit the likelihood of heatstroke. Are you concerned about the amount of perspiration your horse is producing?
Sweating Is About Cooling Down
Sweating is natural and necessary for a horse’s health, and the appropriate amount is required. A person should not be sweating excessively given the circumstances in which they find themselves. When the occasion calls for it, it’s much worse if you don’t sweat at all. In order to keep their equine companions hydrated and limit the risk of heatstroke, horse owners need to understand what constitutes a healthy sweat and what does not. If your horse is sweating excessively, are you worried about it?
A Horse Thermostat
Sweating in the appropriate amount is natural and necessary for a horse’s health. If, on the other hand, they are sweating excessively for the circumstances, this is not normal. Even worse is not breaking a sweat when the circumstance demands it. Horse owners must understand the difference between a good sweat and an unhealthy sweat in order to keep their equine friends hydrated and decrease the risk of heatstroke.

Sweating Might Not Be Enough
If the exercise or stress is prolonged, it is possible that sweating, breathing, and radiant heat loss from the skin will not be enough to bring the horse’s body temperature down. When the body temperature of a horse climbs to 106 – 110 degrees, it is said to be suffering from heatstroke. When the temperatures are high, especially when they are combined with high humidity, keep workouts brief and allow him to cool down between sets. The saying “Walk the first mile out and the final mile back” comes to mind while thinking about walking.
Build up a horse’s bodily condition before asking him to perform beyond his capabilities.
They will sweat more and lose less electrolytes as a result of this. Running a marathon is hardly something you would expect from a “couch potato.” You should acclimatize the horse to the weather if you want to take them somewhere that is different from their normal environment.
Horses That Sweat Excessively
If the exercise or stress is protracted, it is possible that sweating, breathing, and radiant heat loss from the skin will not be sufficient to bring the horse’s temperature down. The body temperature of a horse can reach 106 to 110 degrees, which is considered heatstroke. Exercise should be limited in duration during periods of high temperatures, particularly when combined with high humidity. This will allow him to cool down. One of my favorite proverbs is “Walk the first mile out and the final mile back.” In addition to cooling him down, hosing him down will also relieve him of the irritating dried perspiration that has accumulated all over his body and clothes.
Having a healthier physique will result in less heat being produced.
Running a marathon would be unthinkable for a “couch potato.” You should acclimatize your horse to the weather if you want to take them somewhere that is unfamiliar to them.
- Examine your body for any underlying sickness or injury that might be causing the perspiration. Pay close attention to your eating and drinking habits
- And Pay close attention to your hydration. When does the sweating occur, during activity or in bad weather, or at inconvenient times
- Is there sweat all over, or is it concentrated in one place
- Take a reading of your horse’s heart rate. At rest, the heart rate is 48 beats per minute, which is considered normal. Take your heart rate just after you finish exercising. Then, five minutes later, it happened again. In the 10 minutes following exercise, the heart rate should not be higher than 60 beats per minute. Take the temperature of your horse. The normal temperature is 101 degrees Fahrenheit.
Horses That Don’t Sweat
Examine your body for any underlying sickness or injury that might be causing the excessive perspiration. Make a note of your eating and drinking patterns; Make sure you’re getting enough water. Is it caused by activity or by the weather, or is it caused by unusual circumstances? sweating all over, or just in one location; how much sweating there is; Obtain the heart rate of your horse. At rest, the heart rate is 48 beats per minute, which is normal. It is best to take your heart rate just after you finish your workout.
After ten minutes of activity, the heart rate should not be more than 60 beats per minute.
Temperatures are typically 101 degrees Fahrenheit.
- Sweat should be found beneath the tack and between the rear legs. Depending on the amount of anhidrosis, these regions may be entirely dry or somewhat wet
- Nonetheless, neither condition is desirable. Sides are heaving as a result of rapid shallow breathing with nostrils flared. Maintain an awareness of how difficult it would be for him to breathe after doing the amount of effort he has done
- Does the horse appear fatigued and uninterested in working? The state of one’s hair is thinning, and hair loss on the face might be an early symptom
- Anhidrosis can be diagnosed by a test that veterinarians can provide.
If your horse is not a sweater, you must keep the heat buildup to a minimum. The following is a list of methods for lowering the body temperature of a horse suffering from anhidrosis:
- Allow him to recover his breath by exercising during the cooler parts of the day and taking regular breaks. After an exercise, cool him down with water and fans while maintaining check of his vitals on a frequent basis. Don’t stop until all of your vitals are running at regular speeds. Make sure that all of the turnout spots are well-shaded. Check to see that the horse is getting enough of air and fans if he is being kept in the barn. A mixture of vitamins, amino acids, and minerals may be beneficial to horses suffering from anhidrosis in some circumstances.
In all honesty, horse perspiration is one of the more uncomfortable aspects of horsemanship. Sweating, on the other hand, is necessary to keep the horse cool. When it comes to being a good horse owner, we must be aware of our horse’s sweating, including how, why, and how much. If our horses are sweating excessively or insufficiently, we must intervene to ensure that they remain hydrated and that their body temperature is reduced. A high body temperature might result in a heatstroke if the body temperature rises too quickly.
The secret behind that lathery horse sweat!
When working in hot conditions, a particular protein in horse sweat called latherin operates by wetting the hairs and allowing water to flow more freely for evaporation.

- Lathering is a common side effect of this, and it may be observed on the coats of sweating horses, particularly in areas where rubbing is taking place.
- It’s all because to a particular protein found in the sweat that has been given the term latherin.
- The findings were published in the journal Ecology and Evolutionary Biology.
- Their findings were published in the open-access journal PLoS One.
- As a result of its ability to significantly reduce water surface tension at low concentrations (and hence serve as a wetting agent), it is likely to be used to aid evaporative cooling through the use of a waterproofed pelt.
- at the air-water interface.” The protein, which has been discovered in the mouths of horses, zebras, onagers, and asses, is related to a family of proteins that had previously been discovered solely in the mouths and adjacent tissues of mammals.
As a result, it is possible that horses have evolved an oral/salivary mucosal protein that serves two specific functions for their lifestyle, namely the necessity for quick and effective heat dissipation and the specialisation required for masticating and digesting vast quantities of dry food material.
However, horses have a thick and waterproofed coat that prevents the quick transfer of sweat water from the skin to the surface of the hair, which is required for evaporative cooling.
“This protein, latherin, is thought to work by wetting the hairs to allow water flow for evaporation, with the unfortunate side effect of lathering being noted on the pelts of sweating horses, particularly where rubbing occurs,” says the author.
In recent investigations, it has been demonstrated that biological surfactants offer additional potential for antibacterial action or as anti-adhesive agents against microorganisms.
The researchers noted that “interestingly,” they wrote, “human skin secretions are also assumed to have a surfactant-like role in promoting the dispersion of sweat water for cooling, however by a mechanism that is suited to an essentially hairless surface.” It was noted by the authors that “depositing significant quantities of protein through and over the pelts of horses would appear to carry the risk of serving as a nutrition source for microorganisms.” Accordingly, it is possible that latherin’s surface activity may also have an effect on the surfaces of microorganisms, preventing them from adhering to or establishing themselves on hair and skin.
However, despite the fact that latherin is distantly related to proteins that are directly anti-microbial, the researchers were unable to discover any interaction between latherin and normal bacteria.
Although a simple small molecule detergent would ordinarily be exceedingly harmful to a cell’s membranes, it is feasible that proteins might be engineered to fulfill detergent-like tasks without causing damage to cell membranes.” Horses and their ilk, they said, had developed a remarkable adaptation of a salivary protein for heat dissipation from skin, and Latherin was an easily available protein with which to investigate the intrinsic surface activity of a naturally folded protein from a mammal.
Latherin is a surfactant protein found in horse sweat and saliva that has been identified by McDonald et al.

- Lathering is a common side effect of this, and it may be observed on the coats of sweating horses, particularly in areas where there is friction.
- Everything happens as a result of a unique protein found in the sweat that has been given the term latheerin.
- Rhona McDonald is a professor in the Department of Ecology and Evolutionary Biology.
- Surfactants such as latherin are found in large quantities in horse sweat.
- “This detergent-like action is connected with the production of a thick protein layer.
- In the horse, zebra, ostrich, and ass, the protein is comparable to a family of proteins that was previously exclusively discovered in the mouths and adjacent tissues of mammals, according to the National Institutes of Health.
It is possible that horses have developed an oral/salivary mucosal protein for two functions specific to their lifestyle, namely their requirement for quick and effective heat dissipation and their specialisation in masticating and digesting vast volumes of dry dietary material.
“Horses, on the other hand, have a thick, waterproofed, hairy coat that would ordinarily obstruct the quick transfer of sweat water from the skin to the surface of the hair, which is required for evaporative cooling.
“This protein, latherin, is thought to work by wetting the hairs to allow water flow for evaporation, with the unfortunate side effect of lathering being noted on the pelts of sweating horses, particularly where rubbing occurs,” explains the researcher.
The potential for biological surfactants to be used as antibacterial agents or adhesion inhibitors against germs has recently been demonstrated in new investigations.
This suggests that latherin’s surface activity may also have an effect on the surfaces of microorganisms, preventing them from adhering to and establishing themselves on the hair and skin, among other things.
Their findings indicated that it was necessary to investigate the potential that latherin’s surface activity posed a threat to mammalian cells.
As a result, they concluded that Latherin represented a remarkable adaptation of a salivary protein for heat dissipation from skin by horses and their ilk, in addition to being an easily available protein with which to examine intrinsic surface activity of a naturally folded protein from a mammal.

- In addition, circulation of blood draws heat from the muscles and transports it to the lungs, where part of the heat is expelled when the horse exhales, and to the skin, where heat can radiate out from the horse’s body. If the horse generates more heat than he can expel by breathing and radiative cooling, his core temperature begins to climb over the typical resting temperature (99-100 F)
- This is known as overheating. It is detected by a region of the horse’s brain called the hypothalamus, which is responsible for a variety of other functions, including acting as his central thermostat. It sends messages to the sweat glands that are spread across his skin in a flurry. The sweat glands begin to produce sweat as soon as they are activated. Despite the fact that it is primarily water, it also includes dissolved minerals known as electrolytes. The concentration of electrolytes in a horse’s sweat is higher than in your perspiration. Heat is removed from the skin via transpiration of perspiration, which results in the horse’s body temperature being reduced.
Sweating increases in proportion to how hard the horse is working (or how hot the weather is). He has the ability to create more than twice as much sweat per square inch of skin than you do. During strenuous activity (cross-country running, polo, endurance racing), he can lose 10 to 15 liters of fluid in an hour through perspiration and water vapor that he exhales with each breath, depending on the intensity of the activity. The amount of loss is dependent on weather conditions as well as exercise levels, and it can occur even if you do not notice perspiration dripping from your horse’s brow.
- Because of the nature of his perspiration, he may be sluggish to replenish that fluid as well, as his thirst response is delayed.
- The fact that your horse’s perspiration has a higher concentration of electrolytes than yours means that he is less likely to develop an electrolyte imbalance and is less likely to become thirsty.
- This may not be a significant issue if the stress is brief—for example, if he exercises for only a short period of time in hot weather—and he has a chance to calm down afterwards.
- The difficulty is exacerbated by the hot and humid weather.
- He continues to perspire, but it makes no difference.
- Another factor is physical condition; as horses gain in fitness, they become more adept at controlling their body temperature while exercising.
- The ability to become acclimated to the heat also makes a difference.
- As well as ensuring that your horse is physically fit for the task you want him to do and has been accustomed to the climate in which you ask him to work, these precautions can assist prevent overheating.
- Exercise should be avoided in hot and humid conditions. Pay close attention to the Heat Index, which is a statistic that takes into account both air temperature and relative humidity to determine how hot it feels. A key to the index may be found at the National Weather Service’s website. Allow him to drink. While at a show, provide your horse with water on a free-choice basis, or at the absolute least every hour—don’t wait until you return to the trailer. Trail rides should be planned to include stops at streams or other drinking holes. Three percent of your horse’s water loss is enough to have an impact on his or her performance. Look for signs of heat stress, including as changes in his body posture and urge to feed as well as freedom of movement and muscular relaxation, in order to assess if he is feeling discomfort from the heat. Check for dehydration by using the “skin-tenting” test described in the next section.
Depending on the horse, the tipping point can vary, but for any horse, a buildup of body heat causes weariness, which can have catastrophic implications. It is especially dangerous to combine lengthy periods of intense work with hot, humid weather since it can be fatal. The Danger Zone is where you are. He will overheat and may possibly suffer from heat stroke if your horse is unable to control his own body temperature. (When your horse suffers from heat stroke, his sweating system fails, and his temperature quickly increases to 106-110 degrees Fahrenheit.) If he sweats excessively, he will be at danger of dehydration, which will interfere with vital activities such as circulation and digestion, as well as causing organ damage.
Dehydration can be lethal in the most severe circumstances. Here are five red flags to look out for:
- He’s breathing heavily—and he’s going to keep breathing heavily. When exercising in warm weather, rapid, shallow breathing is frequent
- However, respiration should decrease to your horse’s normal resting rate after a short period of time (below 20 breaths per minute for most horses). If the rate remains high, it is possible that he is panting to cool down
- His temperature remains elevated. During heavy exertion, a horse’s temperature can reach 106 degrees Fahrenheit, but it should return to normal fast when the task is completed. If the temperature does not decrease by a degree or two within 20 to 30 minutes, you should be concerned
- He appears dejected and fatigued. When a horse is dehydrated, he may refuse to eat since horses don’t eat when they’re dehydrated, but he will almost always accept water. A horse that is extremely dehydrated, on the other hand, may become despondent to the point that he refuses to drink
- His skin may become brittle. Pinch a fold of skin in three locations: at the midneck, high on his shoulder, and low on his shoulder to see how he responds. A healthy amount of water will cause his skin to snap back quickly
- A deficiency in fluids will cause it to remain curled up for a few seconds before gradually flattening
- His gut is silent. Place your ear or a stethoscope on his flank and listen carefully on both sides of his body. Many healthy bubbles and gurgles are desired
- However, little or no noise indicates potential problems. He draws on the water in his intestines, which normally contain considerable volumes of water, to supplement his daily water intake. When a person begins to dehydrate, his gut motility slows down significantly. Constipation can cause digestive difficulties such as impaction or ileus (a condition in which material stops passing through the colon).
Take immediate action to aid your horse’s recovery. Get him out of the sun and into the shade.
- To assist him in cooling down, hose or sponge him with cold water—but keep in mind that water must evaporate in order to have a cooling impact. When the weather is hot and dry, the water you apply may evaporate rapidly. The horse’s skin will quickly heat up when exposed to humid air, and this layer of insulation will actually delay the horse’s cooling down. It is necessary to scrape it off, spray it down again, and repeat the process until the water no longer heats up. (In rare situations, a bath containing alcohol may be more effective at dissipating heat than water.) If there is no wind, set up a fan to assist disperse the heat by moving air through the space. Even better, use a misting fan to wet the area. During certain three-day events and other contests, these fans (which you may see) employ water vapor to reduce the temperature of the air
- They also allow the athlete to drink to replace fluids lost via perspiration. Giving him a glass of water after a workout will have no negative effect on him. It’s almost usually fine to let your horse to drink a little amount of water-up to a gallon-and then walk him for a few minutes before offering him more water. When he drinks sporadically, a gallon at a time, you may be able to keep him hydrated longer
- Supplement with electrolytes as needed (see “When Does He Need Electrolytes?” for more information). This will assist him in recouping the losses he has suffered as a result of sweating and will also stimulate thirst.
Is it necessary to contact your veterinarian? That is dependent on the severity of the symptoms and the overall attitude of your horse. As long as his vital signs are improving and he is attentive, drinking water, and showing an interest in green grass, you should be able to deal with the matter on your own. Consult your veterinarian if he appears dull or confused, refuses food or drink, or does not appear to be cooling down despite your attempts. If your horse is in poor health, he can examine the situation and deliver fluids through a stomach tube or intravenously, as well as provide additional supportive care if necessary.
- If you don’t intervene, his body temperature may remain dangerously high.
- Anhidrosis is the word used to describe this ailment in animals.
- It might manifest itself gradually or all at once, depending on the situation.
- Whatever the case, it is critical to acknowledge it and deal with it.
- In warm weather, a dry coat after work is recommended. Because the severity of anhidrosis varies, your horse may be entirely dry under his gear or between his hind legs, or he may be a little moist between his hind legs. His skin is dry and heated, with the exception of those areas. Breathing that is labored during and after exertion. As he takes fast, shallow breaths in an effort to remove body heat, his nostrils flare and his sides heave with each exhale. For the amount of labor he does, he breathes more heavily than you would anticipate, and he continues to do so even after the activity has ended. On a hot day, he may even breathe heavily when at rest, as a means of compensating for his inability to sweat effectively. Performance was below par. In the beginning, he may appear lazy and apprehensive to labor, but he soon grows weary. It’s a bad coat. Anhidrosis is characterized by thinning and loss of hair on the face and body, which can be severe. There is a possibility that this is an early symptom of the illness.
Anhidrosis can be diagnosed based on the symptoms alone. There is also a “sweat test,” in which a veterinarian injects a little dose of the medication terbutaline beneath the skin of the horse’s neck to see if the animal is sweating. Normally, this causes local sweating in a horse, but does not create sweating in a nonsweater. Identifying and preventing heat buildup in your horse’s body, as well as dissipating the heat he cannot shed via sweating, are critical steps in caring for him.
- Exercise him first thing in the morning or last thing in the evening, when it’s not too hot outside. Take regular rests, enabling him to catch his breath before asking him to put up any more effort. After work, cool him down forcefully with cold water and fans, as indicated on page 46 of this manual. Keep an eye on his vital signs and don’t give up until they’re back to their usual levels. When he’s out in the yard, make sure he gets plenty of shade. Alternatively, turn him out at night and keep him in the barn during the warmest part of the day (with plenty of air and a fan). One AC (Miracle Powder Company) is a supplement that has been shown to be beneficial for some anhidrotic horses. It’s a blend of vitamins, amino acids, and minerals, among other things. According to the manufacturer, horses often begin to sweat again after 10-14 days of beginning the supplementation regimen.
Horses who have stopped sweating in hot and humid areas frequently recover after being exposed to colder temperatures for an extended period of time. Theoretically, persistent heat and humidity overstimulate the sweating mechanism to the point where it malfunctions and causes it to shut down. The mechanism has a better chance of reviving under cool, dry circumstances. When Does He Require Electrolyte Supplementation? Electrolytes are minerals that are dissolved in the horse’s bodily fluids, where they aid in the prevention of dehydration as well as the regulation of muscle activity and other physiological functions.
As a result, your horse may experience electrolyte depletion at a time when he is most in need of them.
Most likely not.
Veterinary specialist Duncan Peters, DVM, believes that most persons oversupply electrolytes.
Horses that require supplements include those that compete and train at high levels (eventing at Preliminary and higher levels, combined driving, polo, endurance) and in extremely hot or humid situations (for example, endurance horses).” When it comes to sweat loss, there are few instances when electrolyte supplementation makes sense:
- If your horse has worked hard enough to sweat profusely (his neck, chest, and sides are moist, not just a patch under the saddle), a single dosage of electrolyte replacement can help him replenish electrolytes that have been lost. The stress of hauling the day before a large show may cause your horse’s electrolyte pool to be depleted, according to Dr. Peters. If you haul the day before a big show, a dosage of electrolytes that night will make up for whatever deficiency he may have caused by the stress of transport. Besides that, it may urge him to drink after the journey, which will aid him in rehydrating himself before the tournament begins. However, you cannot “preload” your horse with electrolytes the night before an event since he will excrete the excess electrolytes. If a horse isn’t drinking well, supplementary electrolytes can aid by increasing thirst in the animal. Dr. Peters, on the other hand, believes that horses that freely tuck into high-quality feed and who have free access to clean water and a salt block consume enough water without the need for additional electrolytes. Endurance racers frequently provide sodium and potassium electrolytes half an hour before the start of a race and at regular intervals throughout the competition, depending on environmental circumstances. Preventing dehydration is the objective, and this is accomplished by maintaining fluid balance and inducing thirst. “However, the horse must still have fluid, which means he must be given opportunity to drink,” Dr. Peters points out.
If possible, provide electrolytes orally, as a paste, dissolved in water (in a bucket separate from the horse’s drinking water), or mixed with the horse’s feed. You can take a high-quality commercial supplement (which should include at least 60% electrolytes and no more than 40% sugar), as long as you follow the dose guidelines on the label of the supplement. Alternatively, you may manufacture your own by combining three parts table salt (sodium chloride) with one part “light” salt (potassium chloride).
Always make sure there is clean water around.
Peters emphasizes the need of forage or feed in the horse’s diet, since a slurry of pure electrolytes might irritate the horse’s mouth or cause it to vomit if the horse is on an empty stomach.

They do, in fact! Horses, like other animals, have sweat glands, and they are no different from other animals. Sweating is extremely beneficial to a horse’s health. Heat build-up is relieved through sweating, which is part of a horse’s cooling mechanism. A horse may sweat (and should sweat) while it is exercising; it can sweat when it is in pain, under strain, or sick; and it can sweat when it is stressed or worried. It is common to witness horses sweating when on a trail ride, competing in a race, or even while being trailered about.
How Do Horses Sweat?
Horses sweat, according to Dr. Duncan Peters, DVM, in order to cool themselves off and bring their temperature back down to normal. For example, according to Peters: “When you exercise, your muscles create heat; heat is a consequence of energy metabolism.” Horses expel heat through their respiratory system and through their skin. If these movements are not sufficient to decrease heat build-up, the horse’s sweat glands will kick in and begin pouring out perspiration to cool him down. Horse sweat differs from human sweat in that it does contain water, but it also contains more electrolytes than human sweat, making it more beneficial to horses.
Seeing white foam or lather on a horse’s coat indicates that the animal is dehydrated and is losing electrolytes.
The majority of horses use between 10 and 20 liters of water each day.
The average horse may shed around four gallons of perspiration every hour when working out in the pasture. Of course, this is dependent on a variety of factors, including the weather, how much the horse is exercising, how long the horse is exercising, and the horse’s degree of fitness.
Keeping Your Horse Comfortable
There are a variety of methods for cooling down your horse after an activity session. Take your horse for a walk until its breathing returns to normal. Walking your horse for an extended period of time is dependent on how much exercise you received, your horse’s fitness level, and the temperature of the environment. The higher the relative humidity of the ambient temperature, the longer it will take for your horse to cool off completely. The majority of horse owners and riders will walk their horses out to the pasture, tie the horse up, remove the horse’s gear, and then give the horse a bath or spritz the horse down with water once they have finished.
A horse shower is a great technique to remove the perspiration from your horse’s brow and legs.
Warm water aids in the removal of perspiration residue that has accumulated on the horse’s skin after they have cooled down.
Warm water also has the additional benefit of reducing muscular pain.
It is beneficial for a horse to sweat after an exercise session. It informs you that the horse’s system is operating as it should be operating. Make sure that your horse has access to fresh water at all times in order to maintain the health of his sweat-system. Even if you are displaying or going on a trail ride, make sure to provide your horse with water at least every an hour throughout the day. Do not wait until you have returned to your trailer or barn to provide your horse with water. Try to keep your horse on its feet and walking if at all feasible if your horse is sweating excessively (whether or not they are exercising).
It is possible that excessive sweating is caused by an underlying sickness or condition that need medical treatment.
It is quite effective to wash away perspiration, dirt, and grime from your horse’s coat and coatline, leaving him clean and feeling fantastic!
