Reply to Cheryl's Post: Her hair and tail were very thick prior to the prednesone. The immune disorder: About 4 months ago,she got large red/purple bruises on her tummy which rapidly spread over her body and then she began to have blood come from her nose and mouth. Emergency vet said she was bleeding internally. We almost lost her (5 yrs old), but thanks to the medicines and the predisone she seems sooo much better. At first she swelled up so badly that even her eyes were squinty, but she has almost returned to her pre-ill weight and look. Then, just recently, I noticed hair everywhere, followed by clumps in her fur which needed to be brushed out. But now she is becoming almost bald in her hind-quarter area, especially noticable on her once fluffy tail. She is still not quite as energetic as she was, but you'd have to know her to notice. Thought this might just be a small problem solved with a vitamin or something - will get her to vet if you think it could be more serious. Thank you, Customer (name blocked for privacy)
