A horse with thrush usually has an odor with a black, oozing discharge around the frog. There are several home remedies that can be effective.
The hoof should always be cleaned thoroughly first with dish soap and warm water before applying anything.
Apple cider vinegar sprayed on the hoof daily.
Tea tree oil with a little added alcohol applied twice daily directly to the area. Then cover the foot with clean material such as a sock.
Apply zinc oxide ointment to the area.
If the problem persists, consult your vet.
