If your horse rolls violently and kicks at their belly, you know something’s wrong. That’s obvious.
But what about the horse that’s just… a little off? The one that seems slightly withdrawn, or whose behavior under saddle has shifted in ways you can’t quite pinpoint?
Here’s the thing: horses are stoic. Evolutionarily, showing pain made them vulnerable to predators. So they learned to hide it. Which means by the time pain becomes obvious to us, it’s often been building for a while.
The riders who catch problems early aren’t lucky — they’re paying attention to the whispers before they become screams.
Why This Matters More Than You Think
I’ve seen too many horses labeled as “difficult,” “lazy,” or “resistant” when the real issue was undiagnosed pain. The horse that pins its ears during girthing isn’t being dramatic — it might have ulcers. The horse that won’t pick up the right lead might not be “behind the leg” — it might hurt.
Research has identified 24 specific behaviors that indicate pain in ridden horses. Many of them look like training problems. Head tossing? We blame flies or a busy mouth. Reluctance to go forward? Must need more leg. Bucking? Attitude problem.
But often, it’s pain talking.
The Subtle Signs to Watch For
1. Changes in Facial Expression
The Horse Grimace Scale is a research-validated tool that looks at specific facial markers: the position of the eyes, ears, nostrils, and mouth. A “worried eye” with tension above the eyelid, tight nostrils, or a clenched jaw can all indicate discomfort.
You know your horse’s face. If something looks different — even if you can’t articulate what — trust that instinct.
2. Social Withdrawal
If your normally friendly horse starts avoiding you, their herd mates, or seems emotionally flat, pay attention. Horses in pain often become withdrawn. They might stand at the back of the paddock instead of meeting you at the gate. They might seem checked out during grooming.
This isn’t always dramatic. Sometimes it’s just… quieter than usual.
3. Posture Shifts
The rocked-back stance of acute laminitis is obvious. But chronic pain creates subtler postural changes — standing with weight shifted, parking out slightly, or holding the neck differently.
Don’t dismiss a “funny” stance as a quirk, especially if it appears suddenly or gradually worsens.
4. Behavioral Changes Under Saddle
This is where it gets tricky, because training problems and pain can look identical:
- Head tossing — often blamed on bit contact, but frequently pain-related
- Reluctance to go forward — might be the back, the hocks, the feet
- Girthiness that’s gotten worse — ulcers, saddle fit, rib discomfort
- Bucking, crow-hopping, or threatening to rear — especially if new
- Inconsistency — good one day, terrible the next, for no apparent reason
The pattern I see most often: a horse that’s progressively getting “worse” in training, despite the rider doing everything right. That’s not a training problem.
5. Changes in Movement Quality
Lameness that’s grade 3 or 4 is visible. But grade 1 lameness? That subtle shortening of stride, that slight hesitation, that feeling like they’re not quite tracking up the way they used to?
Sometimes the only sign is that something feels different. The horse isn’t lame, exactly. Just not themselves.
6. Stereotypic Behaviors
Weaving, cribbing, wood-chewing, and other repetitive behaviors can be coping mechanisms for chronic stress or pain. If these behaviors appear or increase, don’t just treat the symptom — investigate the cause.
7. Resistance to Specific Movements
A horse that suddenly can’t (or won’t) do something they used to do easily is telling you something. Won’t bend left anymore? Struggles with downward transitions? Refuses to stretch down? There’s often a physical reason.
What to Do When You Suspect Pain
1. Document what you’re seeing. Write it down. Take videos. Note the date and context. This helps you spot patterns and gives your vet useful information.
2. Rule out the obvious. Check saddle fit, bit comfort, hoof balance. These are common culprits and easier to address.
3. Call your vet. Don’t wait for it to become dramatic. A proactive lameness exam or wellness check is worth it. Describe exactly what you’re observing, even if it sounds vague.
4. Consider the whole picture. Is anything else going on? New environment? Changes in turnout? Diet shifts? Stress can amplify pain and pain can create stress.
5. Trust yourself. You know your horse better than anyone. If something feels off, it probably is. You’re not being paranoid — you’re being a good horse owner.
The Takeaway
Pain in horses rarely announces itself with flashing lights. More often, it’s a subtle shift — a look in the eye, a change in attitude, a movement that’s just slightly different.
The best thing you can do is know your horse’s baseline. What do they normally look like? Feel like? Act like? Then notice when something changes.
Your horse can’t tell you they hurt. But they’re showing you, if you know how to look.
