I have a german shepherd/ akita mix and she has been having this problem with her skin. She scratching alot, and when she does she scratches little patches of fur off from scratching so much. Her skin has little pink and purple spots on it. I would really like to know what's wrong with her. I am worried. Can someone please help!!! I already called around to some vets but all the vets around here said they really didn't know, that they would have to see her but I can't afford a vet bill right now.
