Thrush is a bacterial infection, and one of the most common diseases, affecting horses’ hooves. You will likely know it when you see — and smell — it. The pungent, tar-like black discharge collects in the sulci, or grooves, along the sides of the frog, the triangular structure that covers about 25 percent of the hoof’s bottom.
If thrush is left untreated and progresses into the sensitive tissues, the infection can move into the deeper grooves, causing the frog to deteriorate and resulting in great pain for the horse. In severe cases, lameness is possible if the thrush penetrates the sole and starts to erode vital structures in the foot. Sometimes, portions of the diseased frog will need to be removed by an equine veterinarian or farrier.
If thrush is diagnosed early, it is easy to treat and will heal properly. In addition, there are precautions you can take to help prevent the condition, given that it is most commonly associated with poor living conditions. For instance, horses that often stand on damp and dirty surfaces are more prone to developing thrush, because the bacteria that cause the condition thrive in this type of environment.
