This thread has been very helpful and reassuring to me. I rescued my sweet Jasmine Rose when she was three years old and lost her last October. She was r&w with a very short coarse coat and she never did shed much - that was my only basenji experience. In November, our sweet Ivy came to live with us - a six year old b&w girl with a soft thick coat. What a difference! Then, in February, she started to shed, and shed, and shed - it was like cat hair all over the place. I didn't mind dealing with it, but I was worried about her. She has a heart condition and she's on two medications and prescription food, and since I had never seen such shedding I was worried that something was wrong with her. Maybe an allergic reaction… No redness or itching or any other symptoms but I was worried enough to take her to the vet to have her checked out. Long story short - I was told to wait and see. Now I know she's not the only one to go through this and that blowing out most of her coat isn't unheard of. The shedding has stabilized now and she's all set for summer! The one strange thing is that the underside of her curly tail is just about bare, so when it curls up on her back it looks like there's a channel there - the rest of her tail is still pretty full!
Anyway, just wanted to thank all of you for posting about your experience and giving me some reassurance.
