I have a daschund who is 1 year and about 7 months. He is very eager and friendly and in really good shape. I switched him from Iams to Nutro a while ago, and the dandruff he used to have has completely gone away because his skin is of course better moistened. But just recently, I have begun to notice little bald spots on his tail. I thought at first that it was just dirt stuck there, but when it wouldn't come off I looked closer to discover the balding. He is also experiencing some balding on the backs of his ears. But everywhere else is fine. We live in Utah which is extremely dry, and for that reason we do not have any fleas. I use people shampoo on him from time to time, but I am very careful to wash it off entirely, I have also used it on my English pointer who hasn't had any reaction whatsoever, and in the past I used it on ferrets who were fine. One experienced balding, but she had a very serious thyroid disorder and the balding was evident everywhere. Otherwise than the balding, he is acting fine. I was just wondering if anyone could tell me what might be going on.
