Conformation Education - A Basic Illustrated Overview
Definition of “conformation” from Random House Dictionary:
1. manner of formation; structure; form, as of a physical entity.
2. symmetrical disposition or arrangement of parts.
A horse’s conformation, in essence, is its build and physical structure. It is the organization and alignment of the bones, muscles, tendons, and ligaments. The equine athlete is analogous to a finely tuned machine: All of the parts must be working correctly, and to do so, they must be shaped and fit in a way that is conducive to their intended purpose. For this reason, a basic understanding of equine anatomy and conformation is a great skill for any horseperson to have. These are especially important considerations when selecting a performance prospect or breeding stock.
In the equine world, this is merely the beginning of the subject of conformation. As anyone quickly realizes who has watched the judging of halter and in-hand classes at horse shows, the appraisal of the conformation of the horse can be strongly influenced by the opinion of the judge. Well-established authorities on conformation in the horse world such as Deb Bennett and George Morris have strong views about conformation: the way the horse is put together for the breed it represents, the purpose for which it is to be used and finally, the way in which the horse travels. Their drawings, photographs and explanations regarding conformation can be dauntingly tedious, and no doubt controversial among many competent horse people. Yet, they do exhort us to pay attention to an important consideration: a horse’s conformation—physical structure—can strongly influence its suitability and soundness for the use intended.
A horse with mild pigeon toes or cow hocks may fail in halter competition yet be desirably suitable for trail riding on treacherous terrain or certain kinds of performance competition. Certain breed standards such as those of Saddlebreds may require a way of traveling that would be completely unsuitable for a Standardbred driving horse. Endurance horses require standard of conformation that may be irrelevant for a school horse for novice riders. A broodmare who can successfully weather the stresses of pregnancy requires a certain conformation to be able to carry the weight and demands of the developing foal to a full term delivery. A stallion’s conformation should be a serious consideration in terms of the foals he may sire. If the stallion has significant conformational deficits such as parrot mouth, or other anatomical issues that might be of concern to that breed’s standards, he should be gelded and never used for breeding.
At the most fundamental (and perhaps most important) level, we strip away everything but the skeleton. It is often difficult to visualize the bones on a living horse, but with practice and careful scrutiny of anatomical drawings, the task becomes manageable and even fun. The skeleton is the framework upon which everything else rests.
First, look at the legs—these are the most important parts of a horse’s physique. They support the considerable weight of the body. They balance a horse through its movement and tight turns and absorb the concussive shock of running. The front legs support 60% of a horse’s mass. They should be straight when viewed from the front; angular (“offset”) legs result in undue stress being placed on the joints, possibly leading to future soundness problems. The circumference of the leg bones should be large enough to support the size of the horse and the tack and rider it will eventually carry. Look at the slope of the pastern—the shock absorber of the lower limb—too straight, and the gait will be stiff, choppy, and rough; too sloped, and the ride will be smoother, but the tendons may suffer from hyperflexion, which could lead to chronic lameness and soft tissue injury.
Above: The horse at the left exhibits calf knees or backwards knees, a severe conformation fault with potential lameness implications if used for strenous athletic work. The middle horse shows perfectly straight legs with solid strong bone structure. The horse at the right is slightly bent over at the knee, perhaps caused by hard use earlier in life. This is more consmetic in nature than truly detrimental. All horses pictured above have good angle to their pasterns and adequate length, though some disciplines might like them to be marginally longer for smoothness in gait. The middle horse has good ratio of bone length from upper to lower leg (short cannons are ideal for greater speed and fluidity of movement). The horse at the right has slightly longer-than-ideal cannon bones.
The hind legs, while generally less plagued by chronic soundness issues, are nonetheless important to consider. Watch out especially for hocks that are too straight (“posty”). Without an adequate angle to the joint, too much stress is placed on the horse’s whole hind end, which may eventually cause long-term problems such as arthritis. While not ideal, hocks with excessive angle (“sickled”) are far less likely to cause lameness or negatively impact performance.
Moving down the legs, now look at the feet. As the saying goes, “no hoof, no horse.” Generally speaking, the larger the hoof, the better. This provides good circulation and blood flow throughout the horse’s whole body, as each step helps pump blood back up the vertical veins. A large hoof also helps to distribute a horse’s mass over a bigger surface area, preventing any one point from having too much built-up pressure. The slope of the hoof should match that of the pastern. The foot should also be healthy, with a large, well-defined frog, thick wall, and adequate heel. A farrier can work wonders on a problem hoof, but only if the proper conformational structures are there to begin with.
Now examine the horse’s topline. Look for a good set of withers to hold the saddle in place. Tall, thin withers might be difficult to fit and may require special pads to place the saddle properly. Flat “mutton” withers, on the other hand, will cause a saddle to roll, no matter how tight the girth is fastened. The length of back is also worth considering. A short back is generally considered a good thing, but excessive shortness can lead to over-reaching and interference between the hind and front legs. It can also result in a rougher gait. However, a short back is very strong—think of a suspension bridge. Conversely, a longer back is weaker and over time may become sore or begin to atrophy and become swayed. As with most things, a happy medium between the two extremes is best.
Next, draw an imaginary line from the peak of the withers to the point of the shoulder. This is the shoulder’s slope. Again, look for a good angle. For good balance, the angle here should match that of the front pasterns and hooves. As before, a shoulder that is too straight will cause roughness of movement. A more sloping shoulder leads to greater length of stride and freedom of movement.
On the front end, the shape of the head is often a matter of personal preference, although some believe that skull structure predicts personality and temperament. The throatlatch should be slender to facilitate bending and flexion. The neck should have adequate length to allow for collection. “Ewe necks”—those where the muscling underneath exceeds that on the crest—cause a horse to carry its head sky-high and hollow its back, both undesirable. The “correct” length and set of a neck will vary greatly depending on breed and discipline.
Above: The first horse displays a typical upside-down or "ewe" neck--the length of the bottom exceeds that of the crest, and the muscling underneath is also heavier. This causes a horse to carry its neck and head erect, hollow its back, and limit collection. To an extent, this mode of carriage and the muscling of the neck can be improved through proper training and conditioning. The middle horse displays a lovely neck and carriage for a stock breed. The neck may tie in slightly low, but the length and thickness are excellent, and the throatlatch is fine and clean, meaning that the neck is flexible and aids in collection. The third horse has an overly-thick "bull neck" and thick, inflexible throatlatch, as well as some over-muscled "ewe-ing" on the underside. In addition, the heavy fatty crest suggests obesity or possibly metabolic problems. All horses in the above photos possess adequate shoulders, though the horse on the right is closest to ideal (being laid back and nicely sloped), while the first two animals have slightly straighter shoulders.
Finally, travel back to view the slope of the croup. This, too, is contingent upon breed and discipline. Arabian breeders, for example, prefer a very flat croup, while Western speed event riders like more slope to help a horse “get under himself” better in the fast stops and turns.
***While it is helpful to break a horse down piece by piece, as outlined above, the entire animal should be taken into consideration as an integrated unit. The subjective sense of “balance” is important. Watch the horse move and see how its gait reflects its conformational structure and how it will help or hinder its intended use. Oftentimes small conformational blemishes can be more than made up for by other aspects. That elusive quality called heart also factors heavily in performance and athletic ability. However, analyzing the conformation of a horse helps to predict what future soundness problems might occur, so that preventative measures might be taken accordingly. It can also be used to predict successful participation in a discipline and evaluate the suitability of breeding stock. In the end, it is the comfort and happiness of horse and rider that matter most.
Have you read Dr. Deb Bennet's lengthy treatises on conformation? She has wonderful explanations similar to yours and really goes into the role of the "ring of muscles" in developing collection and a healthy spine and self carriage.
I've read some of her articles in Equus. Obviously she's the expert, but I sometimes find her descriptions too convoluted and technical. I'm annoyed and off-put, I guess, because it's always her horses who have the perfect conformation and her riding that is the best. Her multiple-issue treatise on the importance of head conformation rather got on my nerves....
I'd like to read her books and see her videos, but from what people who have met her have told me, I'm not sure that I could stomach them.
I have heard that she is hard to get along with.
The think that I find interesting is her explanation of why and how certain conformation points translate into certain actions being easier or harder for a horse to do. AND she talks a lot about how conformational faults can be those the horse is born with (most of them) OR can come about by poor riding of the rider. Such as Ewe necks ( or at least the exaggeration of one that is inborn but not huge into a bad one through misriding).
And she explains in detail WHY we do all these training things that have been written about in books for centuries.
However, I must agree with you that sometimes I do not see what she sees. I suppose we all see what we want to see, to a certain extent.
Awesome post ! (Hi,I'm a newbie.lol)
Tiny, I've gotten a bit irritated by some of the horses who she praises as having "great" conformation that, to me, are not all that exemplary. But again, she's got her PhD in equine anatomy (or something of that nature), and I am far from a conformation expert--just someone schooled by hard knocks, experience, and people who know better than me--so it's quite possible that I haven't a clue what I'm looking at. At least she's nowhere near as frustrating as the Conformation Clinic articles in Horse and Rider....those are awful and frequently make me mad. A horse with horrible calf knees is placed ahead of a horse with a less-than-stellar head....gah.
I have this older book written by a British fellow regarding conformation and of course, it is totally skewed toward what a Hunt horse looks best. He shows examples of a typical QH head and calls it "coarse". That is really ethnocentric judging. But sticking to what is biolgically effective is best.
I know--drives me nuts. Of course, the things that win at AQHA halter classes drive me crazy, too....
I like your writing. It is simple and to the point. I enjoy reading conformation articles by different people so I can get different perspectives to an extent. This was a good read, thanks!
