Any reviews of this brush? I ordered one for my Katie Scarlett. I believe she has a cottony coat and I have noticed her tangling more than she used to. I used the yorkie splash and shine for the first time yesterday and am really pleased but I know she needs a better brush. I bought a basic one from petsmart when we brought her home and I don't care for it. Any tips on caring for a cotton coat? I love my baby so much and want to keep her looking and feeling as good as I can. Thanks!
