If the horse develops thrush, provide the horse with a clean and dry environment to stand. Clean the bottom of the hoof and frog area by removing any debris and wash the area thoroughly. Do not utilize a thrush remedy that contains caustic chemicals such as turpentine, formaldehyde, copper sulfate, or chlorine. Hoof disinfectants containing iodine are ideal. "Sugardine" treatments utilizing sugar-betadine solutions packed into the frog sulci have been found to be effective in many cases. Surgical debridement of affected tissue is sometimes necessary.
