What Is A Grulla Horse? (TOP 5 Tips)


  • What Is A Grulla Horse? A grulla horse or grullo horse is a member of the dun horse family that is also known as a blue dun, mouse dun, or gray dun. Its coat is lighter than its mane and tail, and it is often distinguished by being mouse-colored or tan-gray.

What kind of horse is a grulla?

Basically, it’s a dun horse. A grulla has a dark stripe down it’s spine, shoulder stripes and leg barring. A grulla horse is fairly rare, as these things go, and is often the result of mating a black stallion with a red or dun mare. You can see some pictures of grullas at shiningchorses.com.

What breed is a grulla?

Grullo horses aren’t a particular breed; they’re just black horses with a dun gene that causes the black to become diluted. They often have primitive markings that give them away, and you can tell them by their gray or mouse coloration.

What is a grulla mare?

Grulla (or grullo) is a color variety of dun, a coat color of horses, recognized by tan-gray hairs on the body with dorsal stripes on the back and black point coloration on the lower legs, mane, and tail. For this reason, some horse enthusiasts use grulla to represent a mare and grullo to denote a stallion.

What colors make a grulla horse?

To be a grulla, the horse must carry the basic body color of a/a, then carry at least one dun gene. The dun gene is represented by D. Because the modifier dillutes the basic black body and puts the dun markings on the black body, the resulting color is grulla.

How tall is a grulla horse?

Grulla horses have dark-tipped ears, a large head relative to the rest of their body, and dark legs (usually black or brown). These characteristics need to be present for a horse to be considered a part of the Grulla group. The average height of a horse is around five feet.

Do grulla horses have a dorsal stripe?

Grulla or grullo, also called blue dun, gray dun or mouse dun, is a color of horses in the dun family, characterized by tan-gray or mouse-colored hairs on the body, often with shoulder and dorsal stripes and black barring on the lower legs.

How do you get a grullo horse?

The easiest way to get a grulla foal is simply to breed a grulla to a grulla. This usually results in a grulla foal at least 75% of the time. The reason being that this color, like its close relative black, is a result of mostly a collection of “recessive” genes.

What do you name a grullo horse?

Here are some excellent dun horse names, irrespective of gender:

  • Peanut.
  • Cougar.
  • Dunny.
  • Coco.
  • Penny.
  • Sandy.
  • Sahara.
  • Biscuit.

What is the difference between a cremello and an perlino horse?

A cremello has a chestnut base with two cream genes. A perlino has a bay base with two cream genes. With only one cream gene, it would be considered a buckskin. The only true way to confirm the differences between the two colors is through a DNA test.

What do tiger stripes on a horse’s legs mean?

Leg bars and markings Also called zebra bars, tiger stripes, or garters, leg bars are the most common accessory to the dorsal stripe. Leg bars are most commonly seen on or above the knees and hocks, and reflect the underlying coat color. Leg bars on bay duns are black within the points, and reddish above them.

Why are Gunner horses deaf?

“Gunner” was one. The beloved 1993 stallion, with his bonnet face and floppy ears, lost his battle with laminitis in July. In his 20 years of life, he made an undeniable impact on the reining horse industry and two breed associations—and on just about anyone who saw him or his sons and daughters.

What is the difference between a dun and a grulla?

Dun is created by a dilution gene that causes a horse’s base coat to lighten without affecting the primitive markings and points. Dun genes are dominant and represented by a “D.” Grullas can have only one dun gene and still be a grulla. In simple terms, a grulla is a dun dilution of black hair.

What color is a chestnut horse?

Chestnut is a hair coat color of horses consisting of a reddish-to-brown coat with a mane and tail the same or lighter in color than the coat. Chestnut is characterized by the absolute absence of true black hairs. It is one of the most common horse coat colors, seen in almost every breed of horse.

What is a cremello colored horse?

The standard cremello horse sports an unspotted cream-colored coat, in addition to a white mane and tail. Moreover, it has a distinct pink skin beneath its cream coat, blue eyes, and a pink nose.

Grulla Horse Facts with Pictures

In horses, grulla (or grullo) is a color variation of dun, which is distinguished by tan-gray hairs on the body with dorsal stripes on the back and black point coloring on the lower legs, mane, and tail. Grulla is also known as grullo in some circles. Grulla horses have hair that is similar to that of mice because they have the dun dilution gene as well as the black gene. The phrase ‘grulla’ is derived from a Spanish word that means crane, while the term ‘grullo’ indicates gray horse in the language.

There are many different shades of grulla, ranging from slate grulla to light grulla or silver grulla, silver dun, blue dun, and black dun.

The grulla is known as mouse dun in the Highland Pony, while it is known as gray dun in the Icelandic Horse and Fjord Horse, respectively.

Grulla quarter horses are special.

Grulla is a color coat pattern that is formed by the horse’s genetic makeup and is unique to that horse. A coat’s color is built from the ground up through genetics. Although their organization and impact are difficult to comprehend, I will make every effort to describe them as plainly as possible. Genes are passed down through families and occupy a specific place on a chromosome, regulating the features of living creatures. These units can be found in a variety of configurations and can be modified by other genes.

  1. Two allele genes govern these basic colors: one that causes the color to express itself in the animal’s coat, and another that directs the distribution of black pigments.
  2. A recessive allele is one that is not expressed and does not influence the pattern.
  3. Because the dominant allele is expressed, the coat color is noticeably affected by the allele that has been expressed.
  4. When it comes to quarter horses, grulla quarter horses are distinguished by a black base; black is recessive in quarter horses.

Grulla quarter horses have dark points.

Grullas also have black points, which develop as a result of the presence of a gene modifier, the allele, that directs the horse’s black pigmentation to the points of the horse.

The horse’s outside extremities, lower legs, ear tips, tails, and manes are all considered points. The primitive markings on a coat are the next important aspect to consider. There is a dorsal stripe, webbing on the upper legs, and a stripe across the withers on most primitively marked animals.

Grullas have primitive markings.

Even though the visibility of the marks fluctuates depending on the light, you can generally notice a straight, sharp stripe running down the middle of their back. Because to the impact of a dun component, these marks are seen on the skin. Dun is produced by an adilution gene, which allows the base coat of a horse to lighten without damaging the horse’s original markings and points. Dun genes are dominant, and they are symbolized by the letter D. Grullas can have only one copy of the dun gene and yet be classified as grullas.

Slate-gray or mouse color is produced by diluting the pigment, and it has dark tips, primitive black patterns, and dark eyes.

Grulla quarter horses are rare.

Grulla horses account for less than one percent of all registered American Quarter horses. The passage of time alters our perceptions of what is lovely. Those who enjoy the remarkable appearance of a grulla horse will be taken aback by its beauty. After considerable debate, the hue of this coat is becoming more widely accepted. In reality, it is becoming increasingly coveted, which causes a minor concern for the time being. This coat color is rather uncommon. It is necessary for a mare to have both the dun and the black gene accessible in order to produce a grulla/grullo offspring.

Breeders are attempting to resolve the issue, with some having more success than others.

Even while it is not a perfect solution, they are more likely to generate a grulla or grullo when using this method.

Grulla quarter horses are susceptible to melanoma.

While every horse is capable of developing melanoma, horses with this coat color are more prone to do so than those with other colors. When horses reach the age of eighteen, eighty percent of grulla/grullo horses get it. The good news for quarter horse owners is that their breed has a lower risk of developing the disease. The good news about the melanomas that are identified in patients with gray horse syndrome is that they are often non-cancerous. That does not necessarily imply that they should remain.

The anus is one of the places where they may frequently be found.

If you suspect your pet has a melanoma, you should consult your veterinarian immediately.

Horses may soon be able to benefit from a vaccination against it.

Grulla foals don’t change color.

At birth, grulla and grey quarter horse foals can seem quite similar to one another.

The two coat hues, on the other hand, become more distinct as they age. Greyfoals often lessen in color, whereas grulla foals remain the same hue they were when they were born.

Is the grulla color pattern only in quarter horses?

Grullas are not prevalent in any breed, although they may be found in a variety of them. The grulla/grullo coat pattern may be found in twenty-seven different breeds, which is a significant number. Additionally, grullas can be registered with the International Buckskin Horse Association, which is separate from the American Quarter Horse Association.

The evolution of the grullo color pattern.

Grullo is a Spanish word that means “gray horse.” Grulla is the color of a mare’s coat, which is the feminine version of the color. although they are both the same. In order to comprehend the genetics that resulted in the creation of the grulla horse, one must first look back in time to the progenitors of the contemporary horse. The hyracotherium, also known as the eohippus, was the progenitor of all horses and is considered to be the first horse. Eohippus, which translates as “dawn horse,” is the ancestor who lived the longest.

  1. In fact, it wasn’t immediately apparent that there was any sort of connection between them.
  2. It would be more difficult to identify as a result of this.
  3. It was customary for the morning horse to stand a bit taller than four hands.
  4. On closer inspection, it appears like the coat was essentially dun with a few spots on it.
  5. The eohippus’s tiny brain was gradually enlarged, and the limb bones were fused together as a result.
  6. However, it retained its dun coloration, but it was still not a genuine horse in the traditional sense of the word.
  7. Orohippus is Greek for mountain horse, despite the fact that it did not reside in the highlands.

Mesohippus is commonly referred to as the “middle horse” because of his position in the herd.

Climate change forced the Mesohippus to adjust its ways in order to survive.

It was also most frequently of a diluted coat color, which made grulla conceivable.

Possibly, this horse was one of the forefathers of the Asian and European horses that would later emerge.

Following the Kalobatippus, there were various species of Equus, or modern horses.

These were actual equines, although not all of them were the same breed.

They moved east and south, and zebras eventually made it all the way to Africa.

They are reasonably visible on any dun coat, and the traces of the striping may be seen through the coat if the horse has a light enough hue.

Hunters were most likely the first to mount a horse and ride it.

Horses were first used by many ancient civilizations, particularly for their military.

Horseback riding was developed by the Romans.

It is reasonable to assume that chariot racing existed long before the arrival of the Romans.

There were six different coat colors available at this stage. It became apparent that this was changing as the different horse breeds evolved. While diluted coats had been the norm up until this time, when horses travelled south and west, they began to acquire various coat colors as a result.

Grulla coat colors are created through dilution.

Soon, there were nine different colors, and the dilute wasn’t always the most prominent one of them. The grulla horse came out of these changes; it is a dun variation on a black coat. If you look at pictures of grulla/grullo horses, you can see that the mane, tail, and legs are darker. There is a dorsal stripe, and the legs have points. However, although they produce eye-catching coloration, they were initially considered unsuitable for use in many breed registers.

The Grullo and Grulla horses have quite different looks from one another. Many times, they exhibit rudimentary patterns like as stripes, bars, or shadowing, and their hairs are grey, tan, or mouse-colored, which gives them their name. Even though they go by many names, such as blue dun, mouse dun, and gray dun among others, they all refer to the same species of dun (or dunneduck). Consider these horses, their looks, and some intriguing facts about them as we get a better understanding of them.


In relation to Grullo or Grulla horses, the first thing that the majority of people get incorrect is how to pronounce the name. Because they are Spanish terms, they are not spoken in the phonetic manner in which most people attempt to speak them. Grullo is pronounced as if it were pronounced grew-yo. Grulla is pronounced Grew-ya, which is how you would say it.

What is Grulla/Grullo?

Now that you’ve learned how to pronounce these words correctly, what do they truly represent? Is it a certain breed of horse that they are? Grulla and Grullo are simply terms used to describe the color of a horse, and they are both acceptable ways of expressing it; however, the American Quarter Horse Association (AQHA) accepts Grullo as the right name. Grulla is a Spanish word that meaning gray crane, which is a hue that is comparable to the color of a Grullo horse. Image courtesy of HTurner and Shutterstock.

Grullo/Grulla Colorations

Horses with a Grullo or Grulla coloration are genuinely black, yet the black is diluted and changed by the dun gene, which causes the hue to seem lighter. The horse must be smoke or mouse-colored in order to be considered a real Grullo.

Primitive Markings

Grullo horses are also marked with primitive patterns on their body, such as stripes and bars, to distinguish them from other horses. To a certain extent, these sorts of marks may be seen on all duns, regardless of their color.

Ear Tips

The tips of the horse’s ears, as well as the contour surrounding the ear, will frequently be the darker foundation color of the horse. You may also notice black horizontal stripes that go across the back of the ear. This is normal.

Shoulder or Transverse Stripe

An ordinary shoulder stripe or transverse stripe will start at the withers of the horse’s neck and travel horizontally down the animal’s body.

Leg Barring

Leg barring, also known as tiger striping, is characterized by the presence of bars of the horse’s darker base color that travel up the legs.

Face Mask

The face of a Grullo will frequently be partially or completely covered in its darker base color, which is referred to as a face mask in the industry.

Dorsal Stripe

Withers to tail, this stripe extends along the spine of the horse, beginning at the withers and frequently going quite a distance into the tail. Transverse stripes that run off the main dorsal stripe are common, and they can be any width.


Image courtesy of HTurner and Shutterstock. Circular patterns of the darker base color emerge on the chest, shoulders, and underbelly of the animal. Mottling may also be found on the forearms, shoulders, and gaskins of the animal.


Cobwebbing is a term used to describe lines of black coloring that emerge from the horse’s hide. They’re frequently centered around the eyes and on the forehead, and they might be of varying sizes and lengths.

Guard Hairs

This type of guard hair may be seen in the horse’s mane and tail. They’re white or crème-colored, and they might be found all over the horse’s mane or concentrated mostly around the base of the neck. In the tail, light-colored hairs protrude out towards the base of the tail or spread throughout it, in a similar fashion as the front of the tail.


Grullo horses aren’t a specific breed; they’re just black horses who have a dun gene, which causes the black to become diluted in their coloring. They are easily distinguished by their primitive markings, which are frequently gray or mouse in appearance, and by their gray or mouse coloring. You may use Grullo and Grulla interchangeably because they are two terms that relate to the same horses. However, because they are Spanish words, the majority of people pronounce them incorrectly.

Grullo – Wikipedia

Its body coat is lighter in color than its mane and tail, and it bears clearprimitive markings (a characteristic dorsal stripe, horizontal striping on the rear of the forelegs, and sometimes a transverse stripe over the withers), as well as a dark “dun mask” on its face. It has zebra stripes on the left rear leg, which is visible. The dun gene also results in the development of light guard hairs in the mane and tail. Grullaorgrullo, also known as blue dun, gray dun, or giant mouse dun, is a breed of horse in the dunfamily that is distinguished by tan-gray or mouse-colored hairs on the body, often with shoulder and dorsal stripes, and black barring on the lower legs.

  1. It is important to note that each individual hair in this hue is a mouse-colored hair, as opposed to aroan, which is a blend of dark and light hairs.
  2. Silver grulla can also apply to any grullo horse with a silver dapple, regardless of whether or not the horse is in shadow.
  3. The Spanish word “grulla” literally translates as “crane.” A mare is referred to as a grulla, and a horse stallion or gelding, respectively, according to the origin of the name.
  4. (The original Spanish word is pronounced differently in American Spanish and in Spanish from the Philippines.) To the far as coat color genetics is concerned, all of these hues are dependent on thedun gene functioning as a diluting gene over theblackgene.
  5. If a grulla also possesses the gray gene, it will be born in a mouse tan-gray hue, generally with prominent primitive markings, but will gradually lighten and finally produce a white hair coat as it grows older.
  6. For example, just 0.7 percent of quarter horses registered with the American Quarter Horse Association (AQHA) each year are grulla.

Primitive roots

Thetarpan (Equus ferus ferus) was a cousin of the domestic horse that went extinct in the nineteenth century and was said to have been a grulla coloring, according to historical records. The tarpan has always been regarded as a truewild horse, a wild relative or progenitor of the domestic horse who has not been tamed. The majority of equines known as tarpans were, according to some authorities in the early twentieth century, domestic or wild horses rather than an entirely different species. There have been several varieties established that are grulla in color in an effort to “breed back” (recreate) the tarpan.

One of the earliest attempts in this area was reported in 1906 by James Cossar Ewart, who succeeded in creating a “tarpan-like” horse by combining a Shetland mare with a black Welsh pony and naming it Tarpan.

What Is A Grulla Horse And What Do They Look Like?

If you want to have a better understanding of what an agrulla horse is and learn a little bit about them, we will cover a wide range of topics concerning them in this post. In this tutorial, we will discuss what grulla and grullo horses look like, how much they cost, how they are bred, and the differences between the two breeds. Let’s get started.

What Is A Grulla Horse?

When it comes to dun horses, the grulla horse or grullo horse is the most well-known member of the family, which includes the blue dun, mouse dun, and gray dun. When compared to its mane and tail, its coat is lighter in color, and it is commonly characterized by being mouse-colored or tan-gray in hue. Other distinguishing characteristics of these horses are their black cheeks, dark mottling, dark ears, and other unusual markings that distinguish them from other horses. Grullas can be a variety of colors, but they must have both the dun and the black genes, which determine the color of their coats as well as their primitive markings.

Despite the fact that grey dun horses are frequently exceptionally attractive and distinctive, there are a few traits that must be present in order for them to be classified as grulla horses, which we shall discuss further below.

Consider that grulla horses are not a breed; rather, their markings are what distinguish them from other horses.

What Does A Grulla Coat Color Look Like?

What does one look like, more particularly, is a question. They must possess the following characteristics:

  • They have a noticeable dark dorsal stripe along their backs that runs all the way down their backs and into their tails
  • Ears with dark tips
  • A head that is much darker than the rest of the body
  • Legs that are dark, generally black or brown

If you look at photographs of horses with this colouring, you will see that they exhibit all of the qualities listed above. Why? It is necessary for them to have the black gene as well as a diluted form of the dominant dun gene on top in order to have the grulla coloration. Because of this, each dog has a distinct coloring, with the black serving as a base for primitive markings and the dun serving as the predominant coat color. There aren’t many grulla horses around since black is a less frequent color than chestnut or bay horses, and it has to be paired with the dun gene in order to generate grulla colouring.

Even with a black parent and a dun parent, there is no certainty that the foal will be a grulla color in the end. What other markings do you think you’ll see? Once a horse has demonstrated that it possesses the aforementioned features, it may exhibit other characteristics. These are some examples:

  • Leg bars (with stripes on the legs)
  • On the horse’s neck, there are stripes
  • Stripes on the horse’s back and shoulders (usually a transverse stripe that goes down towards the horse’s forelegs)
  • Stripes on the horse’s forelegs Cobwebs are the stripes on the back of the head that are sometimes referred to as cobwebs. The horse’s eyes have dark rings around them
  • The horse’s shoulders and legs have mottled designs on them. Guard hairs in the mane or tail, especially at the base of the neck or the base of the tail, that are white or cream in color

Keep in mind that the dun gene can be paired with other genes as well, such as the creme gene, to create a more complex effect. Grullas can have a wide range of markings, as long as they meet the first set of requirements. Their colors can range from near-black to silvery white, depending on the individual.

What Colors Make A Grulla Horse?

Grulla horses may be found in a wide range of colors, as long as they are fundamentally some dilution of black in some form. In this article, HorseRacingSense provides a thorough description of how the genes interact with one another and how the dominant dun gene results in the characteristic markings. Keep in mind that these markings can be extremely minor and yet be recognized; a horse whose head is only a shade darker than its body can still be categorized as a grulla if it satisfies the other requirements for the breed as described above (e.g.

  • There are several different colors of grulla.
  • Despite the fact that their primary colors are so diverse, any of these can have the grulla coloring.
  • This is because the stripes and primitive markings are dark.
  • Consider the following characteristics: dark mane, dorsal stripe, dark legs, and dark head; these are all indications of the presence of a grulla horse.

How Do You Get A Grulla Horse?

Gray dun horses are regarded to be a rather unusual breed. It takes an odd mix of colors to produce one of these horses, which makes it difficult to obtain one of these horses by breeding one yourself. However, it is possible, however you will want a certain amount of luck in order to have the appropriate genes. If you are able to do some genetic testing on your prospective parents, your chances of success will be much increased – and you will also know much more rapidly whether the foal is a grulla, as it will not be immediately obvious by sight whether the foal is a grulla.

  • You should keep in mind that you will need both the black and the dun genes to be successful; any other combination will not work.
  • In order to have much success with this, you will need to conduct extensive study and get a deep grasp of horse genetics — or consult with someone who does.
  • You should, however, proceed with caution.
  • Grulla foals and dun foals are commonly mistaken for one another, and it is simple for humans to mistakenly label foals, whether on purpose or by accident.
  • You don’t want to spend more money on a grulla foal only to find out later that you’ve actually purchased a black foal when the foal sheds its coat and reveals its true colors (pun intended).
  • Many are born in light colors and will have a very distinct dorsal stripe, which is particularly noticeable.
  • There is no assurance that a foal will be grulla, however, and it is very difficult to predict the color of a horse’s coat from the color of the horse’s first coat.
  • In order to be on the safe side, you may choose to acquire a horse that has shed its early coat and has its mature colors in order to avoid making a clumsy classification decision.

If you are serious about purchasing a foal, make sure you are aware of what to look for and whether or not you should request genetic testing. If you intend to purchase a grulla horse, make sure to deal only with trustworthy breeders and arm yourself with as much information as possible.

How Much Does A Grulla Horse Cost?

Prices for this color variant vary significantly based on a wide range of criteria, and you are surely aware that they are not inexpensive creatures to acquire in their current form. Be aware of any bargains that seem “too good to be true,” and conduct thorough research on a breeder before making a purchase from them. An adult grulla horse will typically cost between $300 and $20,000, depending on its condition. If that sounds like a broad range, keep in mind that the color is not the only thing that influences the price of a horse; you must also consider the breed you are purchasing, as well as other factors like as its history, age, parentage, and so on.

FAQs On Gray Dun Horses

Almost certainly, you’ve come across the phrases “grulla” and “grullo,” and you’ve pondered what the difference is, if any, between them. Although individuals use them in different ways – and some people use them interchangeably – the truth is that there isn’t a fundamental distinction between the two words. Grulla is the Spanish term for “crane,” which is gray in hue like the horse’s mane and tail. However, because Spanish is a gendered language, many people use the term “grullo” to refer to geldings and stallions, and “grulla” to refer to fillies and mares, despite the fact that “grullo” means “gray horse.” As a result, a stallion may be referred to as a grullo, while a mare might be referred to as a grulla.

How Do You Pronounce Grulla Horse?

In Petkeen’s opinion, both terms are of Spanish origin, and the word “grulla” should be pronounced as “grew-ya.” Although this is not the phonetic pronunciation, learning how to say it correctly can save you a lot of confusion and guarantee that you don’t disgrace yourself in front of breeders and other potential customers. Because “grullo” is also pronounced in an unintuitive manner, “grew-yo,” it’s important to become familiar with both pronunciations, especially if you plan to maintain these types of horses.

What Is The Rarest Coat Color A Horse Can Have?

While grulla coat coloring is uncommon, it is not the most uncommon hue on the planet. What is it, you might think – and according to TheEquinest, it is a color known as white. Albino horses can not live for very long, and this term refers to a horse that is “true white,” as opposed to light grays or horses with diluted coat colors, which are also considered to be “true white.” Due to the fact that they do not have the dominant white gene, the majority of so-called white horses will change color over their lifetimes.

  1. In many cases, horses who are white in maturity begin their lives as dark foals.
  2. They typically have pink complexion and dark eyes, which contrasts with their black hair.
  3. According to HorseyHooves, this gorgeous creature will remain white throughout its whole life, although it is a very new breed, having only been existing for roughly a hundred years at the time of writing.
  4. Because coupling two white horses has a 25% chance of delivering a live foal, it is common for them to be crossed with non-white horses in order to maintain their breeding stock.
  5. Despite this, the grulla horse coloration is still rather uncommon.
  6. As more individuals grow interested in them and the color becomes more often requested, it is expected that this proportion will rise in the next months and years.

However, because they are also difficult to produce, they will most likely stay relatively rare for a long period of time, despite the fact that some breeders claim to have strategies that are consistently effective.

Grulla horses have a wide range of markings that might be difficult to distinguish for someone who is not familiar with them. When trying to discern whether or not a horse is a grulla, keep an eye out for black ear tips, leg barring, and the dorsal stripe, among other characteristics. Because they are members of the dun family, they should be colored in a dun hue. When it comes to deciding the color of horses, it’s incredible how complicated the process can be. If you want to breed or even simply better understand the genetics that goes into determining color and markings, you’ll be researching for quite some time.

We’ll get to it in a minute, but first, let’s talk about: Recall the post from a few of days ago about the Spanish term for a dust storm or a haboob, tormenta de polvo? Now, a member of the Gila River Indian Community has suggested that we use the word “jegos,” which he claims is the O’odham word for such an event and the Tohono O’odham word for “jegos.” The O’odham people are native to Arizona’s central and southern regions. He explained that it is pronounced “jug-GOS.” I suppose you could make an argument for that, but then again, you folks are capable of making an argument for just about anything. Anyway, here’s what I have to say about Grulla: The International Buckskin Horse Association uses the spelling “grulla” to refer to the horse. The term “grullo” is used by the American Quarter Horse Association. “Grew-yah” or “grew-yo” are both acceptable pronunciations. Choose whatever option appeals to you. It is a color of horse, not a specific breed. Different shades of grulla exist, ranging from a sort of mouse-colored hue to a blue-ish tone in appearance. In essence, it’s a sham of a horse. A grulla is distinguished by a black stripe running along its back, shoulder stripes, and barring on its legs. A grulla horse is a rather uncommon breed of horse, and it is usually the product of a black stallion mating with a red or dun mare, according to the literature on the subject. On the website shiningchorses.com, you can view some photographs of grullas. The origins of the term grulla are also unknown. An example of this is the Spanish name for a slate-gray crane.

What is a Grulla Horse?

A Grulla or Grullo (pronounced grew-yuh or grew-yo) is a kind of dun horse that belongs to the genus Grulla. The term “Dun” refers to the dun gene, which is a dilution gene that influences both the red and black pigments in the horses’ coats, as well as the color of the horses’ coats.

What Colors Make a Grulla Horse?

Horses are born with a primary color of either red, bay, or black as their starting point. These basic colors are controlled by two genes. One enables the color to manifest itself in its coat, whilst the other guides the black pigment to specific spots on the animal. Grulla horses have black spots on their bodies. The horses’ “outer extremities” are represented by the points. This includes their lower legs, ear tips, tails, and manes, among other parts of themselves. In addition to their stunning, regal appearance, Grulla horses are also valued for their distinctive markings and black points.

This breed of horse is still capable of being trained for use as racing horses or farmhands.

There are many distinct breeds of horses that may be classified as Grulla, and each horse has a specific function. Some horses are better suited for racing, while others are better suited for agricultural work or other tasks.

Primitive Markings

The visibility of the markings on each horse varies, but the sharp stripe running down the middle of its back can typically be seen on all of them. This creature’s coloration is caused by a dilution gene, which enables a base coat to fade without altering the basic markings and points.

How Rare is a Grulla Horse?

Grulla horses are exceedingly uncommon, accounting for fewer than 1% of all registered American Quarter Horses in the United States. If you wish to obtain a Grulla, purchasing or breeding one are the two most effective methods of doing it!

The most promising option is to breed two Grulla horses. The chance of having a Grulla foal from two Grulla parents has been estimated to be less than 50 percent in various studies, on average. The genetic composition of a Grulla horse begins with a few dominant genes that are passed down through generations. The allele that has been expressed is dominant, and it has a visible effect on the coat.

It may also be referred to as a “invisible gene.”
