I have had her to different vets. We are not sure why she chews. She has three different areas that she chews on right now. I have tried the sock suggestion to try to keep her away from the areas but she is an escape artist. I try to keep antibiotic ointments or aloe vera on the places to keep them from getting infected and that works but they wont heal with her licking and chewing at them. We have other pets but she has been around other pets all her life. I will check with the vet about the cream. So far she doesnt seem to mind the taste of the ointment, aloe or hydrocortisone that vets have suggested using. I have wondered about weekly bathing with a very gentle cleanser that maybe would sooth any irritation she has. Aside from the chewing she appears to be healthy.
