Proud flesh usually occurs on lower leg wounds of a horse, and while it is essentially a natural part of a horse's wound healing, proud flesh is an overcompensation which can be complicated to deal with, meaning as soon as a horse has an injury, professional treatment at a vet is essential. Vets can treat an initial wound correctly, and also advise on managing the wound in order to limit the occurrence of proud flesh.
Proud flesh is actually granulation tissue. This is formed naturally by horses in response to injuries or wounds and is usually harmless, posing no problems to the healing process. Horses are also able to produce granulation tissue much faster than many other animals, which can add to the problem of proud flesh.
Proud flesh can be caused by a number of factors. Firstly, wounds on the lower legs will normally be subject to lots of movement as the horse gets around, which can be a contributing factor to the onset of proud flesh. Limiting the amount of motion around a wound can, therefore, reduce the chance that proud flesh will occur.
Making sure a wound is sutured as quickly as possible is another effective way of limiting the onset of the problem, but this is not always possible depending on the nature and location of the wound.
