Wow...I feel stupid. I didn't even think about shaving her belly! Now that she is mat free I am going to try and maintain it. I keep her brushing sessions to removing only one or two knots at a time. I think her harness is what is causing some of them (come on chattiesmom!! I'm DYING for my new harness!! I'm sure it will TOTALLY be worth the wait

) Thanks so much for your help. I reserve cheese strictly for grooming time, so she knows when the cheese comes out, it times for work!
