Lolli has several scabby spots on her back, and thin patches in her hair. We found them when she got her haircut. Her groomer thought allergies, and she has a vet appointment tomorrow. I don't think it's her food, because she has never had a problem before, so I am guessing it is seasonal. However, I am thinking about switching to a grain-free food anyway, just to see if it makes a difference. Any suggestions for something good but somewhat affordable?
