Q: My mare began to suffer from girth galls last year. I gave her two weeks off for them to heal, but as soon as I started riding her again, the sores reappeared. I have owned my horse for four years and, up to this point, she has never suffered from this problem.

I have tried many different girths and girth sleeves, as well as topical applications of surgical spirit, witch hazel, steroid cream from the vet and salt water. I haven’t ridden for two-and-a-half months, as I’m trying to let the sores heal completely. Can you offer me any advice?
