The Beginner’s Guide to Equine Conformation

Being able to assess a horse’s conformation is an important skill for both horse owners and professionals in the equine world.

Before we dive into this topic, there are two important points that must be stressed:

1: A conformation assessment is not a criticism of the horse

Many horses with what we would consider conformation faults go on to be successful performance horses. Conformation must be assessed to determine whether a horse might be predisposed to certain lamenesses or injuries, and to determine whether a particular horse has the physical attributes necessary to perform a desired task, as some conformation faults may make them unfit to do so. By being aware of our horse’s physical abilities and limitations as dictated by their conformation, we can adjust our training and riding methods and expectations, which will in return allow us to work with our horses in a way that better suits them, and that will yield better results .

2: Always consider whether you are looking at “man’s judged opinion”

Dr. G. Marvin Beeman (DVM) differentiates between “man’s judged opinion” and “trial by peer” when it comes to conformation and performance. For example: In the horse show world, the ideal standard for conformation is often dictated by the opinion of judges. This is “man’s judged opinion”. On the racetrack, the standard is set by the fastest horse, which is “trial by peer”. The pitfalls of man’s judged opinion are more often recognized in the canine world, with many people criticizing the “overbreeding” of dogs such as French bulldogs and pugs.

Breeding practices who seek to develop or magnify specific characteristics can lead to genetic issues and predispositions to various ailments (e.g. skin conditions, allergies,...), and sometimes have to rely on inbreeding to maintain a desired look. Many horses are bred for a single purpose, with breeders looking to produce a specific color, size (large or small) or futurity performance. Producing an animal with a conformation conducive to long-term soundness is not always a factor taken into consideration.

The horses pictured above couldn’t be more different when it comes to conformation. Still, in all of them, we can see which characteristics they were bred for: the halter horse was bred to have extreme musculature, the Arabian horse was bred to have a staggeringly dished face, and the reining horse was bred to have a large and robust back end.

Once again, the goal here is not to criticize man’s judged opinion but to teach you, the reader, to recognize sound conformation across breeds and breeding practices.

Develop a system for assessing conformation

“Conformation” is determined by how bones relate to one another, so you must learn to see through fat, muscle, color, and size to evaluate conformation properly.

To develop a reliable system, you must look at every horse the same way, every time. Ideally, you want to look at horses from the side, ensuring that they are standing on level ground, standing square on all 4 feet.

Do not overcomplicate things: at this stage, we are not looking to identify specific conformation faults. All you are trying to do is develop an eye to determine whether a horse’s build is balanced and proportional. The human eye is naturally drawn to proportional things, so if something looks slightly off, it probably is!

While looking at the horse in the position described above, isolate these 3 sections from one another in your mind: 1: the horse’s front-end, including the head, neck and front limbs. 2: the horse’s mid-section, or the trunk. 3: the horse’s hind-end, including the buttocks and hind limbs.

Step 1: Ask yourself, “do all the parts of this horse belong to one another?”

Consider the pictures below:

This horse has a large back end and a midsection that are fairly proportional to one another, but the head and neck are short and small and look like they could belong to an entirely different, much smaller horse.

This horse has a proportional back end and midsection, but the neck and head are comparatively much larger.

This horse has a head that is relatively proportional to the hind end, but the neck and midsection are excessively long in comparison.

Step 2: In your mind, put the horse in a box

The lines of your box must touch the following points

1: The chest to the ground

2: The withers to the lumbosacral joint

3: The buttocks to the ground

On a horse with good conformation, your box should be reasonably square. A horse with a disproportionate build will cause your box to look more like a rectangle. Horses with uneven top lines will not fully fit into a box.

Step 3: repeat

Remember that for now, all you are trying to do is learn to look at every horse the same way every time. The box exercise may sound simple, but it requires practice. Once your brain can easily put every horse in a box, you’ll be able to move on to making more complex conformation assessments and single out specific conformation faults.

This is a fairly well-balanced horse. The front end, midsection, and hind end are proportional to one another. The body forms a square box.

The midsection and hind end are proportional to one another, but the head and neck are large in comparison. The body forms a slightly horizontally elongated box, but the horse can't "fill it" because the top line is uneven. The lumbosacral joint sits lower than the highest point of the withers.

From the front end moving back, everything gets bigger and bigger. The horse appears to have a small head and a very large hind end. The body forms a slightly vertically elongated box, but the horse can't fit into it because the top line is uneven. The highest point of the withers sits much lower than the lumbosacral joint.
