I am going crazy trying to figure out what to do about my 3 year old Boston Terrier male's hot spot. He has had recurrent ear infections, so we put him on Royal Canin Hydrolyzed protein diet kibble (soy based protein). His stomach issues cleared up and he is basically healthy. But after the ear infections (3 of them since November) when he was treated with a variety of meds from the vet and the infections cleared up, he started to lose hair on the backs of his ears. It isn't getting worse, and some has grown back a little, but it still isn't great. Concurrently, he has had a red hot spot off and on since January, which I've been treating with Muracin ointment. The spot gets better, and then three or four days later, it can re-appear, and spread and looks red to light pink in color. I took him to a Dermatologist who scraped and did a culture for ringworm, but it's still coming and going, and he does not have ringworm. Now I'm thinking he has some sort of environmental allergy, or maybe an allergy to the soy in the hyperallergenic food! I am so confused. By the way, this red spot is NOT itchy, nor does it seem to be at all painful. Is that typical of a hot spot?
