Our boxer Jesse, starting getting bald spots on his sides and ears. We took him to the vet, they said it was allergies and to change his diet. We now feed him Blue Buffalo. It didn't help. The one thing that did help was "Ultra Oil". It has anchovy and sardine oil in it. That's the safest oil, less mercury than the other fish oils. All his hair is now back except for his ears. I know it works because I ran out, ordered more and it was on back order. He went 3 weeks without it, and his hair started falling out again. I now order way before I run out. Still havent fixed the ear hair loss, but he constantly scratches them. the vet has tried several prescriptions, but none of them have worked. Does anyone have any suggestions.
