I have a female chow that scratches all the time. She would only let my husband bath her and groom her. Since he passed away she won't let you get close enough to do anything with her. I have been giving her flea capsules in her food but she scratches all the time. She has pulled all the hair or it has came out of her lower back. I know what mange looks like and this isn't mange.I had a dog once with what the vet called a skin allergy and this is what it looks like. Is there any treatment I can get over the counter? If not how can I calm her down enough to get her to a vet?
Your vet can give her a sedative and maybe shave her down for you. Good luck, vetcare
