I have an English Bulldog who is 8 years old. His name is Rocky. Rocky has alopecia, extremely pink all over. He's got scabs on his back hind legs. His ears are dark pink around the edges, looks like a burn color. He's got the big sores in between in toes. We took him to the vet twice. The first vet told us it was more than likely a food allergy. Being allergic to Beef, dairy, and grains. So we put him on a vetrinary prescribed diet for the recommended time. He was also put on an antibiotic. It seemed to start helping but was short lived. Took him to another vet, who still claimed food allergy. Switched him to another food. He seems to only be getting worse. He also has a big pinkish red spot on his chin. Can someone please help me?
