Our dog Sadie 4 year old collie/cross has had no other symptoms other than ulcerations on her nose and peeling on the nose and some hair loss around her eyes. We took her to the vet and they want to do a biopsy to determine if its an autoimmune issue. Ive been feeding her a BARF diet for about a week now. Since her immune system could possibly be her issue shes very susceptible to infections, so ive read. Could the RAW diet be possibly dangerous to her instead of beneficial? Alopathic vets just dont get the raw feeding,mine pretty much freaked out on me today for feeding raw diet, they find it very dangerous. Im very emotional about what to do. I just want to help her naturally without giving her steroids and other medications. She otherwise is very healthy and has NO other symptoms.
