My yorkie LOVES her brush. I'm not kidding. We use the Chris Christensen pin brush, and we use a Madden comb. If I use any other brush, she gets mad at me, but she loves that Chris Christensen. I've tried it on my hair and my daughters hair, and it is an awesome brush. Well worth the money.
I use the 20mm Pocket/Toy brush
HERE but I'm sure that any of these brushes would be great to use.
