I have a friend with a female pit bull mix that he brings with him everywhere. Last time we were hanging out, he mentioned his dog was scratching around her tail. There is hair missing around her tail, and he said that little bumps were coming up, and he asked if I knew what it was. He hasn't taken her to the vet because money is tight right now. I thought it might be flea allergy-related, but I'm not sure. I've heard terrier breeds are prone to getting "hot spots", but I've never actually seen them. Anyone have any ideas as to what it might be? His dog is around Perky (my dog) when he comes over, so I'm concerned in case his dog could spread it to her. I thought mange started around the chest, but I wasn't sure. Any ideas you have on what it could be would be greatly appreciated.
