Is it only my dog............?

My dog sheds like crazy, but her breed is known for shedding quite a bit. Is it visibly noticeable? Like, when you look at your dog, can you see patches or thin areas on the back and tail where the hair is falling out? You should definitely ask your veterinarian. It could be due to your dog getting older, but also due to illness. At least call up there and explain the problem today, and ask what you need to do.
