Our vet said that my Jack has many allergies. My problem is that if you touch her ears she bites and yelps. Obviously they hurt her. The vet said there is no infection and that they are very clean. She said they itch and that's why she bites me. She never scratches her ears. She scratches and licks other places, but never her ears. Any ideas? I hate to see her hurting and the vet is not suggesting anything other than dietary changes.
