Abscess in horses

Abscess

Symptoms:
Abscesses in the hoof are typically characterized by sudden-onset, severe lameness. In some cases, the horse may refuse to put any weight at all on the affected hoof. The horse will be sensitive in the area of the abscess and may have an increased digital pulse and swelling in the lower leg.

A vet or farrier can pare away the hoof to reveal and drain the abscess, confirming the diagnosis. If left untreated, the abscess may erupt on its own through the sole of the hoof or at the coronary band.

Causes:
A hoof abscess is a pocket of infection in the lamina. It can start with a puncture wound caused by the horse stepping on a sharp object in the barn aisle, or a misplaced horse shoe nail. The hole allows bacteria to enter the hoof, where it thrives in the warm, dark environment. While the bacteria eat away at the hoof tissue, the horse's immune system attacks. The resulting pocket of bacteria, white blood cells, and dead hoof tissue puts pressure on the sensitive structures of the horse's hoof, causing the pain response.

Treatment:
Once the vet has located and drained the abscess, the key is to keep the area clean to avoid reinfection. The hoof should be soaked in a solution of Epsom salts in warm water to help draw out any remaining infection. The hoof should be kept bandaged until it has healed. A vet may suggest an anti-inflammatory, such as Bute, to manage the horse's pain. The recovery period is typically no more than a week to ten days, but this can vary widely depending on the severity of the abscess and the owner's ability to prevent reinfection.
