Founder is a common cause of lameness in horses. It involves damage to the laminar connection between the hoof wall and the coffin bone. This often leads to rotation and/or sinking of the coffin bone which causes severe pain and can permanently damage the hoof structure.
How do you tell if a horse has foundered?
- Feeding your horse a large amount of soluble carbohydrates causes an overload of undigested sugars and starches
- High fever or illness causing equine metabolic syndrome (EMS)
- Severe cases of colic
- Stress such as travelling,foaling,or changes in the environment
What causes a horse to founder?
Causes of Founder (laminitis) in Horses Feeding your horse a large amount of soluble carbohydrates causes an overload of undigested sugars and starches. High fever or illness causing equine metabolic syndrome (EMS) Severe cases of colic. Stress such as travelling, foaling, or changes in the environment.
Can a horse recover from founder?
It takes weeks to months for a horse to recover from laminitis. In one research study, 72% of animals were sound at the trot after 8 weeks and 60% were back in work.
How do you know if a horse is foundering?
The signs of founder are easy to recognize: they are the result of both front feet being sore. The back feet may be involved too, but the front feet bear 50% more weight than the rear so they usually hurt more. With both feet being sore the horse’s steps shorten and become slower making the horse or pony look stiff.
What does it mean when a horse has foundered?
Laminitis (also termed founder) is inflammation of the laminae of the foot – the soft tissue structures that attach the coffin or pedal bone of the foot to the hoof wall. The inflammation and damage to the laminae causes extreme pain and leads to instability of the coffin bone in the hoof.
How do you stop a horse from foundering?
To avoid grass founder:
- Allow the horse to fill up on hay before turning out on grass for a few hours.
- Place a grazing muzzle on horses predisposed to foundering to limit their forage intake. Grazing muzzles limit grass intake but allow the horse to exercise throughout the day.
Can foundered horse be cured?
Horses with a mild episode of laminitis may recover, especially if the coffin bone is not displaced. Once founder occurs, recovery is lengthy and the outcome is uncertain. Some cases are euthanized due to pain that cannot be adequately managed. Early identification is ideal for recovery.
Can a horse founder on hay?
Horses can founder even though they are on a senior feed diet. A simple grass hay diet is recommended for horses at risk of foundering. Senior feeds are made with ingredients that are typically high quality and easy to eat; however, horses susceptible to founder may continue to have problems.
How do you tell if a horse has foundered in the past?
Observant horse people recognize the appearance of a “foundered hoof”. These feet typically show several signs in combination: a dished dorsal hoof wall, dropped or flat sole, a widened white line and obvious growth rings or lines on the hoof wall.
Can a foundered horse eat grass?
There is no fructan in warm-season grasses, yet horses can still founder on them. Since the same environmental conditions that create high fructan concentrations also increase sugar and starch levels, it’s best to just limit all NSCs.
Can a horse founder in one day?
You can founder a horse by putting them on an insulin drip for 48 hours, or simply by turning them out onto the equine version of a Snicker’s bar — a green spring pasture. The high sugar content of the grass signals the body to produce even more insulin.
How long does horse founder last?
Founder is a complex condition and weakens the support for the bones inside the hoof, so making sure the hoof strikes evenly is essential to prevent further damage. Much like a broken fingernail, full repair does not happen until the damaged part of the hoof has fully grown out which takes 6-12 months.
Should you walk a horse with laminitis?
Fact: Walking a horse with laminitis will cause more damage to the hoof. Your vet will assess the pain and severity of the laminitis your horse has and may provide pain relief and sole support. Your vet may also advise box rest (movement restriction in a stable) for several months.
What is big lick?
Under normal circumstances, “big lick” action is created by horseshoes that have added pads and weight (sometimes called “stacks”), usually combined with additional weighted chains or rollers placed around the pasterns to create dramatic, high-stepping flashy action of the horse’s front legs, desired in the horse show
Can a horse founder in one foot?
While the term founder is often used synonymously with laminitis, founder refers to the coffin bone actually sinking or rotating, which can happen in more severe cases of laminitis. Although laminitis can affect only one foot or all four, the front feet are most commonly affected.
Founder in Horses – Symptoms, Causes, Diagnosis, Treatment, Recovery, Management, Cost
Preparation is key for any veterinary appointment, so be sure to give the veterinarian everything about your horse’s medical and immunization history. This will preclude a full physical examination, which will include measurements of blood pressure, body temperature, weight, height, temperament, bodily condition grade, heart and respiration rates, and behavioral responses to stimuli. The veterinarian will also do a lameness examination on your horse, which will involve a standing exam to assess his or her look and conformation, as well as probing of specific regions to check for discomfort, heat, and inflammation.
You will next be asked to trot your horse so that the veterinarian may examine the muscles and joints while they are moving.
This may not be necessary because a veterinarian will typically be able to tell if your horse has laminitis by the time it is diagnosed.
This treatment consists of tugging and pressing on the hoof using a particular instrument, followed by an examination of all four hooves to identify the severity of the laminitis.
In addition, the veterinarian will need to take x-rays of the feet to ensure that the coffin bone is in the proper position, and he or she may want to use an ultrasound to get a more thorough image.
Tom Lenz, DVM, MS, has written this article. The beginning of spring may be the most pleasant time of the year, but if we have horses that are prone to grass founder, this season may mark the beginning of major troubles for some of our horses. In particular, horses who are above the age of 10, are easy keepers, and/or are suffering from insulin resistance are more susceptible to grass founder and should be the focus of founder prevention efforts. In the case of laminitis or founder, as it is more popularly known, the laminae, which are delicate and blood-rich, are destroyed, causing the horse’s hoof to separate from the soft tissue of the foot.
- Several factors, including frequent trauma on hard ground (road founder), grain overload, a retained placenta, hormonal imbalance (Cushing’s syndrome), certain medications (corticosteroids), obesity, and lush grass can cause laminitis to develop.
- Insulin is responsible for transporting sugar into the horse’s tissues, where it is required for normal function.
- Because of this, blood vessels in the horse’s foot are being destroyed.
- In extreme situations, the coffin bone may twist through the sole of the horse’s foot, causing an infection that can lead to the horse’s death if not treated.
- Because of the protracted glucose absorption caused by high carbohydrate levels in the grass, as well as the delayed insulin response, insulin dysregulation occurs in otherwise healthy and normal horses (Figure 1).
- Veterinarians and nutritionists have known for a long time that plants store energy in their seeds in the form of starch, which can induce laminitis in horses if they are exposed to grain too early or eat an excessive amount of grain over their lifetime.
- If the fast developing grass generates more energy than it requires during the warm spring daylight hours, it stores the surplus as fructans in its root system.
- Fructans are stored in high concentrations in the stems and leaves of the grass during the spring, when there are bright days followed by chilly nights.
- Later in the year, when the temperature differences between day and night are more regular, the majority of the fructan produced by the plant during the day is consumed by the plant each night.
Following the dissemination of this knowledge, we may develop a number of ways to limit the consumption of fructans by grazing horses as well as the occurrence of grass founder. In order to avoid grass founder, follow these steps:
- Maintaining your horse’s weight with regular exercise and nutrition control is essential. Prevent ‘easy keepers’ and ponies from roaming around in lush, quickly developing pastures until the grass has slowed in its growth.
- Provide your horses with high-concentration legume pastures such as alfalfa or clover to graze on, as these are low in fructan and high in other nutrients.
- It is best not to graze horses on pastures that have been grazed extremely short throughout the winter since there will be a high concentration of carbohydrates in the fresh, quickly developing grass.
- If your horses have cresty necks or are overweight, keep them in their stall or paddock until the pasture’s pace of development has decreased, then gradually introduce them to the pasture.
- Allow the horse to graze on hay for a few hours before sending him out on grass for a few minutes. Grazing muzzles should be used on horses that are prone to foundering, in order to reduce their feed consumption. Grazing muzzles restrict the amount of grass the horse consumes while allowing the animal to exercise throughout the day.
When it comes to grass founder, like with any other health-related concern, your local veterinarian is your greatest source of knowledge.

What Causes a Horse to Founder and Can They Recover From It?
Any links on this page that direct you to things on Amazon are affiliate links, which means that if you make a purchase, I will receive a compensation. Thank you in advance for your assistance — I much appreciate it! It was suggested to us that our horse could have stumbled. Our grandson quickly recognized our anxiety and inquired as to what founder was and why we were so anxious. When a horse develops founder, which is also known as laminitis, it is caused by a variety of factors such as food, genetic susceptibility, and overmedicating.
It is an extremely dangerous ailment that has the potential to cause the horse’s demise.
To avoid and manage this severe and painful disease, you’ll need to be well-versed in a variety of topics.
Understanding the anatomy of a horse’s hoof is critical.
The hoof must first be understood in order to comprehend what happens when laminitis arises before we can discuss the origins of the disease. The adage “no foot, no horse” holds true now just as much as it did in the past. Bone and laminae are found within the hoof, and they are the components that allow the horse to stand and move. Whenever the laminae become inflamed, the horse will develop lameness on that particular leg. That inflammation will begin to spin the coffin bone, producing discomfort and long-term issues, eventually leading to the formation of what is known as founder.
What causes founder?
Horse founder is a dangerous and frequently fatal ailment that can be brought on by a variety of factors, including injury or illness. The following are the most common reasons why horses fail: Feeding horses a diet that is excessively heavy in sugar or starch might lead them to stumble. This occurs when the horse’s digestive system is overburdened by a significant amount of sugary food, resulting in decreased blood flow to the horse’s feet. Make certain that your horse is at a proper weight.
- Horses have a natural need to chew on their cud.
- Overeating in and of itself, as well as weight increase, can cause this.
- Horses require simply grass and hay to maintain their health.
- For example, grain is an useful energy source for horses on chilly days or when they are going to exert themselves physically.
- Your horse will benefit greatly from having some hay mixed in with the grain during feeding time.
- Some grasses, especially if consumed first thing in the morning, can cause laminitis and founder in horses.
- To understand more about the grass that horses consume, you should read Grass For Horses: Why it’s Important and the Different Types of Grass.
- If the adjustment is made too quickly, the horse may suffer from colic.
If you’re a new horse owner, spend some time researching about horse diets and talking to vets and other horsemen who have been in the saddle before. Most veterinarians will advise you to supplement your horse’s hay or grass if it is in need of more energy.
Maintain a healthy weight in your horse’s tack. In comparison to a healthy horse, an overweight horse is far more prone to founder. Equine teething is a natural inclination for them. The animals will consume everything if they are given an excessive amount of grain or unrestricted access to silage. Excessive eating in and of itself, but also excessive weight gain, can cause this. An overweight horse puts greater stress on its joints and ligaments, is less likely to get enough exercise, and is more likely to acquire diabetes, which increases the chance of having laminitis.
- Overfeeding and wrongly feeding a horse is more detrimental to your animal’s health than underfeeding it.
- Too much grain, on the other hand, is unhealthy, and a diet consisting only of grains is not recommended.
- Putting fodder in a hay net allows the horse to consume it more slowly, which is a better option even.
- Particularly if the grass comes from a fresh source, this is true.
- Not only is it necessary for horses to have their diet adjusted gently, but it is also necessary to avoid foundering.
- You should spend some time researching about equine diets and speaking with vets as well as experienced horsemen if you are a novice horse owner.
- Some horse and pony breeds are more prone to foundering than others, depending on the breed.
When it comes to determining what the horse will perform, genetics might play a part.
Instead, provide a soft area for children to run and play on.
One of them is on a motorcycle.
That is not to say that a horse cannot be ridden strongly; rather, it is to say that caution must be exercised.
The shoes that he or she attaches will vary based on the horse’s requirements and preferences.
They have the ability to detect the onset of laminitis before you do.
No matter how skilled the farrier is, some horses will get laminitis as a result of the shoeing process.
In some ways, a horse’s foot is similar to human fingernails.
Horses need to be trimmed on a regular basis by someone who understands what they are doing in order to maintain their comfort and offer the necessary stability.
It can cause the horse to stand at an awkward angle if it is not trimmed on a regular basis, which can lead to. laminitis.
Steroids and nonsteroidal anti-inflammatory medications (NSAIDs) have the potential to develop laminitis over time. Contrary to popular belief, excessive usage is a contributing factor to the disease. When horses are fed a high-carbohydrate diet, the response to steroids is considerably more dramatic than it is otherwise. Horses given steroids after consuming a high-carbohydrate diet were found to be much more likely to develop laminitis, according to the researchers.
- The administration of low-molecular-weight heparin (LMWH) following colic surgery, on the other hand, has been shown to be useful in avoiding laminitis.
- This is due to the presence of a poison in the tree’s bark and leaves.
- They are at danger of developing laminitis if they consume it or if it is present in their stall shavings.
- It is not necessary to spend a large sum of money in order to do this.
- Laminitis can be caused by a combination of factors including the increased weight of the foal and the hormones secreted during pregnancy.
The Symptoms of Founder in Horses
Founder is a medical disorder that can strike at any time and inflict lasting harm to the body. Thus, it is critical to recognize the indications of founder early on and to get your horse treated as soon as possible. Swelling around the foot and ankle joints, as well as a change in stride, are frequently the first signs of plantar fasciitis. Pain may or may not be present at the time of diagnosis. Other signs of founder include a noticeable pulse in the foot, a reluctance to move, and standing with its front legs stretched out in front of it.
It is possible to discern a difference in the sole of a horse’s foot in severe instances, and sometimes the pedal bone is clearly visible.
So, what can I do to prevent founder?
Some of the answers are very self-explanatory. Make sure the horses stay away from anything that contains black walnut, such as shavings, trees, or wood fences produced from the tree! Keep a check on the horse’s nutrition, keep an eye out for weight concerns, and make sure the horse’s feet are properly trimmed on a consistent basis. If your horse is grazing on lush, rich pastures, a grazingmuzzle should be used. The following link will take you to an informative article on grazing muzzles: click here.
Some are more difficult to deal with. When it comes to trimming and shoeing, please consult with your farrier and your big animal veterinarian to ensure that the horse’s feet are balanced. It is not necessary to avoid all drugs; rather, it is important to ensure that they are not misused.
Horses can recover from founder.
Acute laminitis is a condition that can be treated. It is possible that things may improve; however, this is not guaranteed. It is dependent on the underlying cause, the degree of the injury, and the horse. Typically, stall rest is provided to a horse suffering from acute laminitis. You should ideally keep your horse in a stall with soft bedding, particularly one with thick pine shavings or plenty of nutritious hay, in order to decrease the tension on the hoof. Chronic laminitis is a condition that can be treated.
- When a horse is diagnosed with chronic laminitis, the question of euthanasia is frequently brought up in conversation.
- Chronic laminitis worsens over time, eventually causing the horse to be unable to stand because to the tremendous discomfort.
- It may not be possible to save the horse at this point, and the most humanitarian option may be to put your partner out of its pain as a result of the situation.
- It’s never an easy decision to make, no matter what kind of furry loved one we have in our lives.
If you imagine of a healthy coffin bone as being “Velcroed” to the interior of the hoof wall by interlocking sensitive and insensitive laminae, you can better appreciate laminitis (also known as founder). It is known as laminitis when the Iaminae become inflamed and begin to break down, resulting in your horse experiencing laminitis. As long as the inflammation is moderate (as it may be in the case of a stone bruise, for example), there isn’t much of a concern. However, if there is enough cell death to disrupt or dissolve the interlocking link between the hoof wall and the coffin bone, the coffin bone might begin to spin, causing the animal to lose its balance.
- Chronic founder can occur when a healthy horse gets into the grain, has a bad drug reaction, experiences repeated concussion on hard surfaces, has colic surgery, is exposed to black-walnut wood, or has a leg injury or unsoundness that causes a load-bearing trauma on the other leg.
- If you and your veterinarian are able to identify one of these causes, your horse is suffering from acute founder.
- Chronic Founder is distinguished by the presence of more permanent alterations in the structure and blood flow of the hoof wall.
- Long-term high stress from performing, extended medicine, or—and this is a relatively new concept—insulin resistance, a disease I liken to human diabetes, can all contribute to it.
- One consequence of insulin resistance in humans is the development of degenerative alterations in the tiny blood vessels, which is analogous to the development of degenerative abnormalities in the laminae of the foot in horses.
- Despite the fact that chronic founder might manifest itself unexpectedly, you may find yourself dealing with it for years.

The Equine Lameness Exam
If your trail horse becomes lame while riding, contact your veterinarian immediately and request a lameness examination. I’ll walk you through each phase of the lameness examination in this section. In addition, I’ll provide you with the lameness grading method developed by the American Association of Equine Practitioners (AAEP). The more information you have, the more prepared you will be to assist your horse in his rehabilitation.
Living with Founder
Laminitis is a condition that is unlike any other that affects horses. The complicated chain of events that causes the soft tissues (laminae) within the hoof to expand, weaken, and die begins long before any visible indications of disease appear, and once the process has begun, it is exceedingly difficult to reverse. Even more concerning, a severe case of laminitis is likely to result in the formation of a permanent reminder: the founder, which is an internal malformation of the hoof that arises when the supporting laminae lose their hold and allow the coffin bone to rotate down.
- Laminitis practitioners have taken advantage of these discoveries to develop more effective methods of relieving horses’ pain and reducing the forces that threaten to tear their hooves apart from within.
- But researchers in labs, vets in the field, and horse owners faced with the prospect of providing lifelong care for a damaged horse continue to face obstacles as a result of the disease.
- As a farrier and subsequently as a veterinarian, William Moyer, DVM, has treated hundreds of foundered horses over the course of 30 years.
- As he points out, “you can’t always foresee what will happen from one day to the next, let alone one month or a year from now,” which is a sobering truth for anybody who is devoted to caring for a foundered horse, one who has been permanently altered by the disease.
- Even the most determined course of action, on the other hand, will appear to have little or no influence on the situation, and there will be no apparent rhyme or reason for this failure.
- When faced with a lack of solid solutions, Moyer says he delivers the best advise he can, drawing on his three decades of professional expertise in the field.
- According to Moyer, “all I can do is attempt to prepare them for the possibly difficult path ahead,” which generally entails taking a close look at an owner’s expectations for a horse’s health and future in light of the likely realities of the scenario at hand.
- There Is a Cause and a Cure A foundered horse’s condition must be determined at the source before any therapy can be administered.
As Moyer points out, “there is a very strong and entirely natural desire among horse owners to find out what occurred.” “However, there are situations when we will never be able to determine what caused a horse to founder.” Of course, there are instances in which the precipitating event is immediately apparent and the route of therapy is plain.
- Then there are instances in which efforts to determine the etiology of laminitis may help to prevent the disease from spreading to other horses.
- It would be worthwhile to rule out the potential of black walnut toxicosis.
- Despite the fact that it has nothing to do with a horse’s management or health state, it is easy to search for anything–or someone–to blame when something goes wrong.
- He explains that if a horse develops laminitis after getting a single injection, the two occurrences are not necessarily connected, and it is crucial to avoid assigning responsibility in the wrong place.
- The expectation is as follows: A thorough understanding of the many treatment choices for a foundered horse is all that is required to select the most successful regimen for the horse.
- If a therapy is effective for one horse, it is unlikely to be helpful for another.
- Many horses move from painful laminitis to crippling founder, and when this happens, it’s reasonable to want to educate yourself on the many treatment options and management tactics available to you.
- Few hours spent chatting to your veterinarian, farrier, and friends, reading publications and textbooks, and going onto the Internet will produce a wealth of useful–and sometimes useless–information.
- Which of the following measures is the most effective?
- The lack of controlled scientific research comparing one management method to another, according to Moyer, is a major problem.
In addition, Moyer says, “you’ll receive a plethora of advise from everyone, and everyone will have a tale about how they saved a horse they know.” “You should definitely bring it up with your veterinarian and farrier, but please don’t expect it to work for your horse simply because it worked for someone else’s.” “I’ve experienced personally how annoying it can be,” Moyer admits.
- Of fact, a veterinarian and farrier can reduce treatment choices for a horse’s health depending on key criteria of the horse’s condition.
- However, such data simply serves to point the way in the direction of therapy.
- “I really believe that there is something out there that can benefit every horse,” Moyer says of the possibility of finding a solution.
- In this case, the reality check applies not just to specific therapies, but also to the horse’s long-term care and management.
- According to Moyer, “If there was one guaranteed approach to handle a foundered horse, we’d all be doing it.” Progress is still being made.
- The fact is that a foundered horse’s development can vary dramatically from day to day, and even when he appears to have totally healed, he is more likely to show signs of having been afflicted by the deadly hoof disease.
- These stories will warm the hearts and boost the spirits of individuals who are dealing with similar difficulties.
“It is impossible to precisely forecast a horse’s response to therapy or the end fate of his ailment based on how he appears when initially checked,” explains Moyer.
He may even be allowed to return to his prior responsibilities in some cases.
“The only thing that people notice about a horse is that it is healthy, which is fantastic.
He encourages people to hold out hope, but also to prepare for the possibility that a horse’s condition can deteriorate unexpectedly.
Certainly, difficulties of this nature can be resolved, and they will be that much simpler for a business owner to deal with if it is anticipated that they may emerge in the future.
It is a fact of life that caring for a foundered horse can need a significant expenditure of both time and money, as well as much emotional fortitude.
Of course, no one likes to stand by and watch a horse go through a difficult situation.
Recognizing what lies ahead will assist you in taking stock of your resources so that you are well prepared to make the best decisions possible for yourself and your horse in the case of an emergency or disaster.
The successful maintenance of a foundered horse necessitates a certain amount of daily, and at times, taxing effort, according to Moyer, regardless of whether the horse stays on your property or is boarded elsewhere.
A daily visit and one-on-one attention are essential, and they cannot be substituted.
If you have acute laminitis, the cost of an initial veterinarian visit might range between $100 and $500, depending on your location, the diagnostic efforts necessary, and the course of therapy recommended.
A reasonable estimate of the additional costs associated with providing modest care for a foundered horse is $200 per month.
It is not uncommon for trips to university clinics or experts to cost thousands of dollars each.
It is possible that X-rays may be required multiple times during the year, at a cost of at least $200 per session.
Even in such case, there are no assurances for the horse’s survival or long-term health and well-being.
You must decide if you can live with the unpredictability of not knowing what you will discover at the barn on any given day.
Are you willing to put your horse down?
Laminitis and founder are conditions that may one day be prevented through research; however, for the time being, the best that owners, veterinarians, and farriers can do is manage the aftermath in a way that is most beneficial to the horse.
“It’s difficult not to come across as negative, but caring for a foundered horse is extremely challenging.” Nonetheless, having the correct frame of mind and honest knowledge going into it may alleviate some of the stress and aid in the achievement of a positive conclusion.” This essay first published in the August 2001 issue of EQUUS magazine.
What is laminitis, and how can it be prevented or treated? – RSPCA Knowledgebase
Laminate foot laminitis (also known as founder) is an inflammation of the ligaments of the foot, which are the soft tissue structures that connect the coffin or pedal bone of a horse’s foot to the hoof wall. Extreme discomfort is caused by the inflammation and injury to the laminae, which also results in the coffin bone being unstable in the hoof. In more extreme situations, it can result in the entire separation of the pedal bone from the hoof wall as well as rotation of the pedal bone within the hoof wall.
Once a horse has experienced an episode of laminitis, he or she is more prone to experiencing another bout.
Initial (acute) symptoms
- In spite of the fact that all four feet are susceptible to being damaged, the forelimbs are more commonly and seriously afflicted than the hindlimbs. Equine patients that are affected by this condition are reluctant to move and adopt a’sawhorse’ attitude, in which they rock their weight off the most severely damaged forelimbs. Horses suffering from laminitis will frequently lie down. As a result of the intense discomfort in the other supporting forelimb, it will be difficult for you to lift up one of your forelimbs. To the touch, the hoof wall and coronary band (the soft tissue that surrounds the top of the hoof) are frequently warm. When foot testers (a tool used by your veterinarian or farrier to detect hoof pain) are used, there is frequently discomfort, particularly around the toe area. In contrast to analog pulses, digital pulses are powerful and quick (the digital pulse may be discovered at the rear of your horse’s fetlock). Request a demonstration from your veterinarian if you are unsure of how to do this.
This kind of inflammation is identified in situations where the inflammation has been present for a long period of time and structural alterations are now evident:
- “Rings” of laminitis appear on the surface of the afflicted hoof, and these “rings” correlate to earlier bouts of laminitis in the horse. The curvature of the hoof wall is similar to that of a dish or slipper, with lengthy toes. A bulge in the sole corresponds to the rotation of the pedal bone in the hoof when the bone has rotated in the hoof
- Due to restricted flexibility in its front legs, the horse will tend to bear greater weight on its rear legs, which is known as the “laminitic position.”
Overfeeding obese ponies is a fairly prevalent cause of laminitis, especially during the spring months following a period of heavy rain. In grasses and clovers, the soluble carbohydrate content increases as a result of the rain. When consumed, this triggers metabolic changes in the body, which results in altered blood flow to the laminae of the foot and ankle. Among the other reasons are:
- When a horse gets into a feed shed or bin, he may be overfed grain, resulting in grain engorgement. a mare’s placenta remains in situ after foaling
- Situations characterized by septicaemia Obesity (a major predisposing factor in laminitic horses)
- A weakened immune system. Lameness that prohibits one leg from sustaining its own weight, resulting in laminitis in the other supporting limb
- Extreme labor in unshod horses on hard terrain, or over-enthusiastic hoof clipping might result in trauma.
Ponies that are overweight, as well as their crossbreds, are more susceptible to laminitis. Any horse suffering from one of the conditions listed above, on the other hand, may be impacted. Those horses that have had past episodes of laminitis (e.g., hoof rings or slipper-shaped feet) are more susceptible to subsequent episodes of laminitis due to the fact that they have fewer healthy laminae remaining to provide support for the pedal bone. The spring season is when the majority of instances of laminitis caused by overfeeding occur.
If you feel your horse is suffering from laminitis, you should seek veterinarian care right once. A radiograph (X-ray) of your horse’s foot will likely be required depending on the severity of the clinical symptoms. This is done to evaluate how much rotation there is in your horse’s hoof and how much pressure is being applied to the pedal bone. The information gained from this will offer your veterinarian with a baseline against which to measure response to treatment as well as the required information from which to collaborate with your farrier to get the best possible outcome.
To have a successful outcome, early diagnosis and treatment with a strong focus on prevention are essential, as is a positive working relationship between you, your veterinarian, and your farrier:
- First and foremost, eliminate the source of the problem. The removal of horses from their food supply should be done quickly if they have acquired laminitis as a result of overfeeding. When a mare has retained her placenta, it is a medical emergency. Your veterinarian will need to remove any residual placenta, rinse the uterus with saline, and begin necessary medical care right away. Horses suffering from a septicaemic condition will also require vigorous medical care from your veterinarian
- Anti-inflammatories will be the cornerstone of treatment in this situation. According to the etiology, severity, and stage of laminitis, consult with your veterinarian about the most appropriate treatment and dosage rate to be used. Horses suffering from this condition must be kept in thick shavings so that they may dig their hooves into a comfortable posture. Alternately, you may choose to use a sand yard, but it is critical to use a hoof pick twice daily to prevent sand from building up in the sole. Exercise should be avoided during the early stages since it may result in additional rotation of the pedal bone
- Proper hoof care is essential. Your farrier should speak with your veterinarian and trim the hoof in accordance with the degree of rotation of the pedal bone. Ongoing nutritional control is also important. Consult with your veterinarian to determine the most appropriate feeding schedule. In addition to getting additional feed sources that are high in soluble carbohydrate, many feeds that are marketed as safe for laminitic horses are not suited for use in your horse. Until you are able to obtain veterinarian assistance or guidance, feed just hay
- Horses want companionship. You should make certain that horses confined during laminitis therapy have the opportunity to socialize with other horses.
- Make certain that your horse or pony is fed a well-balanced ration that is appropriate for their kind, age, and level of exercise. Access to rich pasture should be restricted, particularly during the rainy spring months. If you fear your mare has retained her placenta (12 hours later may be too late), or if your horse appears to be in any way sick, seek veterinarian treatment immediately. Regular foot care from a professional farrier is essential for your horse’s well-being.

Equine Founder – Causes and Treatment
Equine founder is a word used to refer to equine laminitis, which is defined as inflammation of the laminae in horses. Located between the toe bones and the hoof wall, the laminea is a tissue part of the horse’s foot that provides cushioning and support. This tissue is densely packed with blood arteries that supply nutrients to the hoof. The presence of inflammation in this tissue is problematic. Horses who are overweight are at risk for The Horse as a Founder Equine laminitis is a condition in which the blood supply to the toe section of the hoof is cut off.
If this continues for an extended period of time, the tissue will die and the bones will rotate.
Seedy toes are the term used to describe this condition.
In addition, the bone of the toe actually begins to spin such that it enters the sole of the hoof, as if that weren’t awful enough.
It is necessary to put the horse down at this stage. One of the problems with equine founder is that, once it has happened, the horse is more susceptible to laminitis in the future, which can become chronic if the animal is not constantly managed.
Signs of Equine Founder
Equine laminitis is a painful condition that normally affects mainly the front feet, although it can also affect the hind feet in some cases. Walking or standing will be difficult for the horse, and he will show symptoms of discomfort when doing so. When the horse is standing, he will seek to shift the weight off of his front foot. They will accomplish this by moving their back feet more forward under their belly and extending their front feet forward in an attempt to carry more of their weight on their heels rather than the painful toes of their feet.
Causes of Equine Laminitis
In horses, laminitis can be caused by a variety of factors, the most prevalent of which is grain overload, followed closely by absorption of excessive green grass and abrupt diet changes. One of the other explanations is that the horse is being ridden too hard, especially if the animal is overweight or out of shape. The repeated forceful shock of a horse, such as when it is run on cement or put through heavy effort on a racing track, can also induce founder. Giving cold water to a hot, sweaty horse before allowing the horse to calm down can trigger laminitis in the horse.
- The good news about equine founder is that it may be readily avoided in the first place, and that it can have a positive outcome if treated properly and promptly.
- The overabundance of grain is a crisis.
- If you feel that your horse has consumed an excessive amount of grain, take them to the veterinarian as soon as possible.
- Introduce your horse progressively to green grasses.
- Keep a close eye on horses that are solely fed pasture, as this is especially important.
- The circumstances described above are excellent for the development of laminitis in horses.
- Some horses might get so ill that they are unable to consume green grass or pasture for the rest of their lives.
Prevent Equine Laminitis with Common Sense
- Slow down the rate at which the feed changes
- It is not advisable to run on concrete. Horses in a green grass pasture should be closely monitored. Don’t overfeed grain to your animals. Infections should be treated as soon as possible. Never ride a horse too forcefully
- It might cause injury. Pneumonia may be prevented with immunizations and suitable housing
- Horses should be allowed to cool down before being given water. Keep your horse’s weight at a healthy level
Treating Laminitis in Horses
Horses who have suffered from a grain overload and are taken to a veterinarian are given enormous amounts of mineral oil through a stomach tube to help them recover. This is done in order to prevent the grain from being digested and thereby preventing founder and colic. Antihistamines are frequently administered with caution so as not to induce toxicity. Overweight horses and ponies who have been diagnosed with equine founder are put on a weight-loss diet to help them lose weight. Unless the founder is derived from grass, the animal will not be permitted access to green grass pasture.
Corrective shoeing performed by a qualified farrier can be beneficial on a variety of levels.
This is essential for tissue regeneration and for encouraging the bones of the foot to realign themselves appropriately after an injury.
Acrylic compounds are sometimes used to strengthen and protect the sole of the foot, as well as to build up sections of the hoof.
Severe equine founder can be fatal to a horse if not treated promptly. However, if founder is treated promptly and effectively managed, it can result in a horse that is capable of living a long, healthy, and useful life.

Home Horse Illnesses and Disorders The Horse as a Founder
The beginning of spring may be the most pleasant time of the year, but if we have horses that are prone to grass founder, this season may mark the beginning of major troubles for some of our horses. Horses over the age of ten, easy keepers, overweight, or cresty-necked appear to be particularly susceptible to grass founder and should be the focus of founder prevention efforts. Laminitis, often known as founder, is an inflammation of the laminae of the horse’s foot. It is caused by a bacterial infection.
- Because the sensitive laminae and insensitive laminae lining the hoof interlock with one another, the coffin bone remains firmly in place within the hoof, much like interlocking fingers do.
- The end outcome is a separation of the hoof wall, rotation of the coffin bone, and considerable discomfort.
- In addition to frequent shock on hard ground (road founder), grain excess, retained placenta, hormonal imbalance (Cushing’s syndrome), certain medicines (corticosteroids), obesity, and lush grass all contribute to the development of laminitis.
- In order to survive and reproduce, the bacteria create and release toxins (endotoxins), which are delivered by the circulation to the foot, where they cause damage to the laminae and tiny blood vessels.
In recent years, researchers discovered that grasses not only store energy in their seed heads, but they also store energy as fructan in their roots, leaves, and stems, which they call “fructan storage.” If the fast developing grass generates more energy than it requires during the warm spring daylight hours, it stores the surplus as fructan in its root system.
Spring is a time of year when the grass stores huge amounts of fructan in the stems, particularly those that are close to the ground.
Later in the year, when the temperature differences between day and night are more regular, the majority of the fructan produced by the plant during the day is consumed by the plant each night.
While this new information assists us in better understanding the etiology of grass founder, it also offers us with a number of techniques to minimize the intake of fructans by horses who graze on a variety of grasses. In order to avoid grass founder, follow these steps:
- Hold off on bringing in your easy keepers and ponies to lush, fast-growing pastures until the grass has halted its growth and begun to form seed heads.
- Hold off on bringing in your easy keepers and ponies from lush, fast-growing pastures until the grass has slowed in growth and begun to develop seed heads.
- It is best not to graze horses on pastures that have been grazed very short during the winter months.
- Keep cresty-necked, overweight horses in a stall or paddock until the rate of development in the pastures has decreased, and then introduce them to the pasture gradually if necessary.
- Allow the horse to graze on hay for a few hours before sending him out on grass for the remainder of the day. I have a horse who is prone to foundering in the spring, so I put a grazing muzzle on him before turning him out for a few hours. This allows him to get some exercise while also preventing him from eating excessive grass.

Green Grass Founder – Laminitis
Explore the area surrounding the dry lot. It seems like there’s no way for the horse to get around the barrier and have access to some grass on the other side, yet there could be. Keep in mind that a dry lot implies no grass, not short grass. At this time of year, grass is growing rapidly everywhere, and you’d be astonished how much the horse is actually consuming in one sitting. Furthermore, grass that has been stressed in this way frequently has greater sugar levels. Exercise is the single most effective treatment for EMS.
A second technique is to limit the amount of time the horses spend on the pasture, with the morning being the best time to do so because the sugar level of the grass is lowest.
(This is a tactic that many people use when eating at all-you-can-eat buffets!) Agrazing muzzle is the option that I like.
The disadvantage of this strategy is that certain horses, such as Houdini, are escape artists and will manage to get their muzzles off.
So that’s spring, with all of its benefits and dangers.
The grass turns a magnificent shade of green and begins to produce sugars once more.
When it comes time to answer, you first sequester him in a stall where there isn’t even a speck of greenery to be found.
There will be no alfalfa, no grain, no orchard grass, no apples, or anything else you might imagine.
After that, contact the veterinarian and inform your farrier of the situation.
For the purpose of treating founder, the goals of the game are to reduce inflammation in the foot and to provide structural support.
(This is one of the reasons that treating foundered Cushing’s horses is such a difficult task, but that’s a topic for another time.
Following that, we’ll pack the foot with styrofoam or similar packing material to relieve the pressure on the hoof wall and prevent further damage.
Following that, we’ll look into medications.
A strong nonsteroidal anti-inflammatory drug (NSAID), it will assist in making the horse more comfortable.
I’ll also utilize DMSO, which will be supplied through a tube that will be passed through the nose and into the stomach.
Aside from that, I like making your barn stink.
In the olden days, they’d put the foundered horse in the creek and leave it there.
As of today, you can place the horse in a tub filled with ice water for at least a half hour at a time, repeating the procedure whenever possible.
You can’t put too much pressure on yourself like this.
Of sure, you’d suffer frostbite, but his feet don’t have the same circulation as yours.
If your horse looks to be having difficulty with EMS, we may decide to include thyroid supplements in the treatment plan.
Horses can be hypothyroid, and there are some very fascinating disputes in the scientific literature over whether or not horses may be hypothyroid.
We’ll gradually wean your horse off of this supplement, but it will take some time.
She should keep the heel and shave the toes off of her shoes.
When you elevate your heel, you relieve the stress on the tendon that attaches to the bottom of the coffin bone and pulls it backward.
This allows you to rotate your foot more freely. Forefoot deformity requires extensive treatment and can take months to correct, so you should arrange sessions with your farrier every four weeks until the problem is resolved.
