Please help! I understand what your going through, because we went through with our youngest Yorkie. Its sounds like the same skin infection our Yorkie, Abbey has. I say has, because it never really goes away. She was on the same medicine your little guy is on. We also used medicated shampoos. Nothing was really working, untill I spoke to a breeder that really knew her dogs and yorkies. She told me to address the problem from within. To boost her immune stystem the vet gave her Omega 3 . The problem cleared up, and we have been skin clear ever since. Now I dont know if this works on all dogs or if it was just the right step to take in Abbeys case, but it doesnt hurt to try it. Good luck, with your yorkie baby, Sheilah |
