Bear looks like he's having an allergic reaction on his chest. It's red, scabby and he's licking it lots. The only recent addition is bran as advised by the vet for his anal gland issues (euw!). He is not fed other cereals although thinking anout it,hegets little biscuit treats and bread crusts from my toast. I'm going to stop the bran (and the biscuits) and see if there's an improvement after a week or so. If not, I'll start a raw elimination diet. Meanwhile, is there anything I should put on his scabby bits or should I leave well alone?
