Need more info What are you suggesting when you say underlying condition? That phrase scares me so please could you be more specific? He is pulling out the hair - chewing- No other hair loss except on back legs.. Are you thinking thyroid? I just need all the info I can so I will ask all the right questions to the vet. I live in rural West Virginia so my vet see all breeds of dogs and I am not as lucky to have a vet locally that would see lots of yorkies. She is a great vet and I trust her totally but the more I know the more I can help my furbaby. |
