Hopping lame

Hoof abscess known as pus in the foot - can present in an alarming way but be easily remedied. Here's how to deal with this common problem

IT is not unusual for an abscess to cause a horse to be non-weight bearing on the affected limb, and many a vet has been called to a horse with a “suspected broken leg” that turns out to be an abscess.

A sub-solar hoof abscess, also known as pus in the foot, is a common cause of lameness, particularly in wet weather conditions following a long dry period, as well as during an extended spell of frequent and heavy rain.

It is thought that tiny cracks appear in the hoof wall and allow moisture, dirt and bacteria to enter. Infection sets in, followed by a build-up of pus that, within the restricting hoof cavity, soon becomes extremely painful.

Other cases are associated with puncture wounds to the hoof, while sometimes infection can ascend via the openings left by the tracts of horseshoe nails.

If you suspect your horse may be suffering from an infection in the hoof, arrange a visit from your vet or farrier as soon as possible, as relieving the horse’s discomfort must be a priority.

HOW TO RECOGNISE A HOOF ABSCESS 

BE vigilant for any slight or intermittent lameness that becomes more pronounced until the horse almost bears no weight on the affected leg: 

• More weight may be carried on the toe to protect the heel.
• The affected foot may feel hotter than the other feet.
• There may be a noticeable or pounding digital pulse towards the back of either side of the fetlock.
• The leg may become filled and swollen.
• There may be severe pain and signs of distress.
• If not drained, the abscess will eventually burst through the coronary band.
