Thanks everyone for your input. I really appreciate it. I do have her groomed regularly so all of the dead hair is removed when that is done. She just started shedding that huge undercoat so she has a long way to go before it's all gone. Maybe at her next grooming a lot of it will all come out. She just hates going to the groomers soooooo much that I always feel guilty taking her, but it makes such a huge difference. Well, I'm strongly considering having her shaved to at least try it and see if she is much more comfortable. Thanks again everyone for all of your help. It's so nice to get other peoples opinions, especially a groomer!
