I had the same problem with B'asia this year, especially on the sides of her neck. I put a harness on her and gave her a bully stick. I took it easy and worked in 10 minute increments every day, going over a small section and being very easy. Of course she doesn't like it, but sometimes we have to do what we don't like. That's part of life. When the brushing is done, I take the bully stick and put it in the freezer for the next day. It's so nice to have all that stuff cleaned out! Good luck!
