Today while I was brushing him I noticed a really rough patch of skin on his hind leg that was almost hairless! Ripley normally has very soft, supple skin and very soft hair but the skin on this patch is dry and almost crusty, and the hair is VERY brittle. I can break it if I try to bend it. The rest of his body is perfectly normal, no other bald, dry spots. It doesn't seem to itch, he hasn't licked or scratched at it once. It doesn't seem to hurt, either, I touched it and he didn't do anything. It's slightly reddish compared to the rest of his skin. What gives? If it worsens in the next day or two he's going to the vet, but I'm curious as to what your opinions are too. I've never had this happen to any of my dogs. I will get a picture of it when he wakes up, he's asleep now and that's such a rare thing that I don't really want to bother him.
