Skin turns black and tough after unusual heat cycle
So I'm taking in a retired brood bitch from the kennel I used to work for. Her current owner said that this past heat cycle, a couple of months ago, was odd-- she bled a LOT. Shortly after, all the hair on her belly/thighs fell out and the skin went from white/pink to BLACK. The vet was at a loss and thought it might be hormonal, and assured us that it doesn't hurt or itch. It is not mange. Has anyone else experienced this?
