How Can I Tell If My Horse’s Saddle Doesn’t Fit?

A saddle can appear to fit while your horse is standing quietly and tell an entirely different story once the horse begins to move.

This is one of the reasons saddle fit can be so difficult for horse owners to assess.

When riders think about an ill-fitting saddle, they often look for obvious signs: white hairs, dry spots, soreness, or a saddle that visibly rocks or slips.

Those signs may matter.

But often the first indication that something isn’t right is much subtler.

The horse simply doesn’t move, feel or behave the way he should.

Your Horse May Be Telling You Before His Back Does

Possible signs that warrant investigating saddle fit include:

• Reluctance to go forward

• Shortening of the stride

• Difficulty bending more in one direction

• Resistance during transitions

• Hollowing or bracing the back

• Difficulty developing or maintaining rhythm

• Tail swishing, ear pinning or other behavioral changes when saddled or ridden

• Moving differently on one rein than the other

• A saddle that consistently moves or slips

• Sensitivity through the back

• A previously willing horse becoming resistant

None of these signs proves that the saddle is the problem.

And that distinction is extremely important.

A saddle that moves to one side, for example, may appear to be an obvious saddle-fitting problem. Research has found an association between persistent saddle slip and hindlimb lameness or gait abnormalities.

In other words, sometimes the saddle is creating the problem.

Sometimes the horse’s body is changing how the saddle behaves.

And sometimes both are happening.

Saddle Fit Is Not Just About the Saddle

I don’t believe a saddle should be evaluated as an isolated object sitting on a stationary horse.

I look at the horse, saddle and rider as an interacting system.

A horse isn’t shaped the same way when standing still as when walking, trotting, cantering, bending, lifting the back and carrying a rider.

Research supports this. Studies have documented changes in horses’ thoracolumbar dimensions following ridden exercise, with greater changes observed in horses working correctly and in correctly fitting saddles.

This is why simply placing a saddle on a horse in the barn and declaring that it “fits” can give us an incomplete picture.

I want to know:

What happens when the horse moves?

Does the horse lift and use the back?

Can the shoulder move freely?

Does the saddle remain balanced?

Does it remain stable through changes of direction?

What happens when the rider sits in it?

And perhaps most importantly:

How does the horse move in it?

An Even Sweat Pattern Doesn’t Necessarily Mean an Even Horse

There is another reason I don’t use sweat patterns alone to determine whether a saddle fits.

A horse can be crooked and a saddle can be crooked with him.

If a horse is physically asymmetrical or habitually moves crookedly, a saddle may shift, rotate or settle in a way that accommodates that crookedness.

The resulting sweat pattern may appear beautifully even on both sides.

At first glance, that can look like evidence of good saddle fit.

But an even sweat pattern does not necessarily mean that the saddle is sitting correctly on the horse or that the horse is moving symmetrically beneath it.

A crooked saddle that matches or follows the horse’s crookedness can potentially produce an apparently even sweat pattern while the underlying asymmetry remains.

If we evaluate only the sweat marks, we could therefore reach exactly the wrong conclusion.

This is why I want to see the horse standing and moving, both with and without the saddle and rider. I want to see how the horse organizes his body, whether the saddle follows the movement symmetrically, how the rider influences that relationship, and whether what appears to be a saddle problem may actually be revealing something elsewhere.

The sweat pattern is information. It isn’t the diagnosis.

The Rider Matters Too

Saddle fitting isn’t only about fitting the horse.

The saddle also needs to allow the rider to function correctly.

If a saddle places the rider in a position where they are constantly fighting to remain balanced, the rider’s compensation becomes part of what the horse experiences.

Likewise, rider asymmetry can influence what we see happening beneath the saddle.

Published research into the horse-saddle-rider relationship recognizes precisely this complexity: problems involving the horse, rider and saddle can interact, making it difficult to identify one component without considering the others.

That’s why I don’t separate saddle fit from biomechanics.

Your Horse Changes — So Saddle Fit Changes

Another misconception is that once a saddle has been professionally fitted, the problem is solved.

But horses aren’t static.

Their bodies change with:

• Conditioning

• Muscular development

• Weight gain or loss

• Age

• Training

• Rehabilitation

• Changes in workload

• Injury and compensation

Research following sport horses over a year found considerable changes in back dimensions.

So a saddle that worked beautifully at one point in a horse’s development may not continue to fit the same way indefinitely.

The reverse is also true: as a horse begins using its body more correctly, its musculature and back shape can change.

Saddle fit therefore isn’t an event.

It’s an ongoing process.

Don’t Automatically Blame the Saddle

This may be the most important point.

If your horse suddenly becomes resistant, crooked, short-strided or uncomfortable, don’t immediately assume you need another saddle.

The saddle may indeed be contributing.

But the underlying problem could also involve:

• Pain or lameness

• Hoof balance

• Muscular asymmetry

• Compensation elsewhere in the body

• Rider imbalance

• Conditioning

• Training

• Or several of these interacting at once

This is where I believe we sometimes do horses a disservice by separating everything into specialties.

The saddle fitter looks at the saddle.

The hoof professional looks at the feet.

The trainer looks at the training.

The bodyworker looks at the body.

The rider works on the rider.

But the horse doesn’t experience these things separately.

He experiences one body responding to all of them.

Look at the Whole Horse

When something isn’t working, my first question isn’t simply:

“Does this saddle fit?”

It’s:

“What is this horse telling us?”

The saddle is one part of that investigation.

Sometimes changing the saddle creates an immediate difference.

Sometimes what appears to be a saddle problem leads us somewhere completely different.

And sometimes several small things that seem insignificant individually turn out to be creating a much larger problem together.

That is why I approach saddle fitting as part of a whole-horse evaluation rather than simply matching a saddle to the shape of a stationary back.

Because ultimately, the goal isn’t to make the saddle look correct.

The goal is to help the horse move comfortably, freely and in balance.
