Cellulitis: A Painful Puzzle In Equine Healthcare

Cellulitis can be a frustrating and challenging health concern for horse owners, and incredibly painful for the horse it affects.

A bacterial infection in the soft connective tissues located under the skin, cellulitis can occur anywhere on the body, but often occurs in one of the hind legs. It usually starts with sudden swelling that is warm and painful. As the condition progresses, the horse may develop a fever and his entire leg may become swollen, his skin may crack and ooze, and he may refuse to bear weight on the affected leg. This condition can progress in a matter of hours and life-threatening complications can occur.

The specific cause of cellulitis in horses is not known, but many develop the condition after getting a wound, though the size of wound doesn’t matter. Additionally, decreased blood and lymphatic circulation, breaks in the skin’s barrier, and an increased bacterial population may play a role. In some horses, the cause is never found.

Cellulitis is often treated with a combination of nonsteroidal anti-inflammatories and antibiotics, combined with cold hosing and bandaging with drawing agents. The exact care protocol and medications prescribed will depend on which bacteria are involved. This is determined by culturing the tissues and fluids.

Horses with old injuries or previous episodes of cellulitis are more likely to develop the condition.
