Signs Your Horse May Be in Pain

Subtle changes many owners overlook

Horses are masters at hiding pain. As prey animals, they instinctively mask discomfort, which means the early warning signs are often quiet and gradual. What looks like aging, attitude, or a minor off day can actually be your horse trying to cope with pain.

Paying attention to small changes in behavior, movement, and routine is one of the most important things an owner can do.

Changes in behavior or attitude

A horse that becomes irritable, withdrawn, or resistant during grooming, tacking, or handling may be experiencing discomfort. Ear pinning, tail swishing, biting, or avoiding interaction are common early indicators that something does not feel right.

Reluctance to move or perform

Hesitation when walking, turning, or transitioning gaits is often an early sign of pain. Shortened stride, stiffness when first moving, or resistance under saddle are frequently mistaken for laziness or training issues.

Subtle lameness and posture shifts

Pain does not always present as obvious limping. Watch for uneven weight bearing, shifting weight from one leg to another, resting a leg more than usual, or standing in an abnormal posture. These small adjustments can signal chronic discomfort.

Facial expression and tension

A tight mouth, flared nostrils, squinting or closed eyes, or a dull, guarded expression can all indicate pain. Facial tension is one of the most overlooked signs but can be very telling.

Physical signs that are easy to miss

Some horses show discomfort through:

• Muscle tremors or shaking not related to cold

• Unusual sweating without exercise

• Grinding teeth or excessive drooling

• Lying down more than normal

Changes in eating or routine

Pain can affect appetite and digestion. Slower chewing, dropping feed, weight loss, or changes in manure should not be ignored. Sensitivity to grooming, the saddle, or bridle may also point to localized soreness or dental discomfort.

Signs Your Horse May Be in Pain: When to call your veterinarian

If your horse’s behavior or movement changes and does not resolve, it is worth having them evaluated. Early intervention often means simpler treatment, better comfort, and improved long-term soundness.

If something feels off, trust that instinct.
