Hi, everyone. Norman, our 1 year old, has hair loss on bothflanks. It's been gradual, but it's gotten noticeably worse inthe last month. We took him in and the Vet had no clue what could be causing it. We thought it may be allergies but he doesn't scratch ever. She tested for mites and that was negative. I know it's a common problem, so if anyone has any insight or info it's greatly appreciated. He's on grain free food and we also have a topical spray we use for hotspots as well. The condition is still worsening. Thanks for any help you can provide.
