We never had a confirmed diagnosis, but the dermatologist put Axel on Revolution for 2 months, putting it on every two weeks and a strong antibiotic. He was treating Axel for Sarcoptic mange. It has seemed to take care of most of the bumps, but Axel still has a lot of thin fur. Dermatologist also told us that it was unlikely for Axel to have a food allergy at such a young age, so we have started giving him chicken again and he has been fine. I'm sorry I don't have more info for you and that it took me so long to get back to you. What has your vet told you? I hope your girl gets better soon!
