Where are the withers on a horse?

The withers are the highest point of a horse’s back, located between the shoulder blades at the base of the neck. They’re formed by the dorsal spinous processes of the thoracic vertebrae.

Why are withers important for saddle fit?

The withers determine how a saddle sits. Poor fit can pinch or rub, causing soreness or muscle atrophy.

What causes wither soreness?

Improper saddle fit, excessive pressure, trauma, or repeated friction can lead to sore withers.

What is fistulous withers?

Fistulous withers is a painful condition involving infection or abscesses in the supraspinous bursa over the withers. Veterinary care is required for treatment.

All About Horse Withers: Anatomy, Care, and Common Issues

Withers aren’t just a reference point—they affect saddle fit, comfort, and overall performance. Here’s what every horse owner should know about caring for this vital area.

Anatomy of the Withers

The withers are the highest point of a horse’s back, formed by the spinous processes of the third through eleventh thoracic vertebrae. Their shape and height vary by breed and conformation.

Bony Structure: The ridge of thoracic vertebrae that defines the withers.
Musculature: Muscles such as the trapezius and rhomboids support posture and movement.
Soft Tissue: Skin, fat, and connective tissue provide natural padding and protection.

Care of the Withers

Saddle Fit: Prevents pressure points and soreness—consult a professional fitter.
Grooming: Keep skin clean to avoid irritation or debris buildup.
Blanketing: Check often for rubs or chafing at the withers.
Chiropractic Care: Helps maintain alignment and relieve tension.
Exercise: Encourages stretching, circulation, and muscle strength around the withers.

Common Wither Issues

Even with good management, withers are prone to problems:

Wither Soreness: From poor saddle fit or repeated trauma—watch for swelling and touch sensitivity.
Fistulous Withers: A serious infection of the supraspinous bursa requiring veterinary treatment.
Muscle Atrophy: Can occur from injury or chronic saddle fit issues—rehab and proper fit are key.
Wither Whirls: Harmless hair swirls, though sometimes sensitive to touch.
