A hoof abscess describes a painful build-up of purulent material (pus) within the hoof capsule. It will often be extremely uncomfortable for the horse, causing an obvious lameness at walk. Foot abscesses are caused by bacteria entering the hoof capsule and setting up an infection. The bacteria can enter in a number of ways; often the bacteria tracks up the white line. But it can also occur following farriery or injury such as standing on a sharp object.

Treatment
The quickest way to relieve hoof abscess pain is to drain the exudates buildup. The growing exudates and pressure of the abscess will try to take the path of least resistance. In most cases, your veterinarian will create a small hole through the white line, sole, or hoof wall in order to provide a pathway for the exudate to leave the foot. Once drainage is established, your veterinarian will probably apply some type of poultice or bandage to help pull the remaining exudates from the hoof.
Depending on where the abscess drains, your vet might recommend keeping the drainage site clean until it has had a chance to dry and harden. If this is not possible to find a drainage point, the horse will likely be put on box rest with a hot, wet poultice on to soften the hoof capsule and allow any purulent material to drain. Treatment may include non-steroidal anti-inflammatory medication to control pain and inflammation.
Prevention
Regular hoof care and farriery is an important step in preventing hoof abscesses, but there is no guarantee that your horse will be immune to this problem. While difficult to control, avoiding extremely wet or dry conditions, as well as sudden changes in moisture, can help prevent formation of hoof abscesses. Routine mucking of stalls, pens, or other confined areas can also help prevent them.
