THRUSH

Thrush is a degenerative condition primarily affecting the sulci (clefts) of the frog. The horny material of the frog softens and disintegrates. A foul odor and black discharge are commonly seen in affected areas of the frog. Horses with narrow feet or those kept in damp, dirty conditions are most often affected. Thrush can also occur in dry conditions.

Thrush begins in the depths of the frog sulci and may not be obvious. If ignored or undetected, it can progress to undermine the entire frog. Treatment is simple and usually curative if thrush is detected early. Severe, advanced thrush often requires repeated trimming away of dead tissue.
