Sorry- didn't see this til now- I never have time to stop in here much anymore
Well, the fur doesn't seem to be coming back, but isn't getting any worse either. When we first got Gibs he had what looked like food crusted on the bridge of his nose- I assumed it was from eating wet food and not washing his face afterwards (he had no idea how to clean himself- he was only with his mother for two days before she died, and he wasn't taught by the people who raised him). Onyx has taught him to clean himself, by example, and when he started washing his face after eating thats when the fur seemed to 'disappear'.
I don't think its parasites- wouldn't it spread farther than 1/4" from his nose if it was? It looks like it was physically chaffed off. It doesn't seem to bother him, I was just wondering if it would grow back, thats all.
