My mom got a dog to replace Cindy (it's okay - she's taking much better care of her pets now) and it's a purebred black and tan dachshund. But it has white splotches on its back, so my thought is that it has vitiligo. I seem to recall that it isn't harmful toward dogs, but I want to make sure. So tell me - is vitiligo harmful? EDIT: Well I seem to have found some more info that's telling me no, it isn't. Anyone care to reinforce this thought? Thanks much.
