Hoof abscess are probably the most common cause of acute lameness in horses. Excessive moisture contribute to weakness in the sole-wall junction (hite line) allowing infectious agents such as bacteria or fungal elements to gain entry into the hoof through the white line. If left untreated the abscess will follow the path of least resistance up the hoof wall and rupture at the coronet band. This often leads to a permanent scar in the hoof wall. Another common cause of abscesses is penetration of the sole by a sharp object; infection may also gain entry into the foot by way of a hoof wall crack or multiple old nail holes.
Most affected horses show sudden lameness which varies from subtle to non weight bearing and should be treated by a veterinarian. Treatment may involve opening and draining an infection also pain relief, anti inflammatory medication and antibiotics may need to be prescribed.
If your horse has hoof problems and or lameness always see veterinary advice.
