Bought this to brush my powderpuff Chinese created. His hair is about 6 inches long and gets matted all the time. I was worried because the brush is heavy duty but my dog didn’t mind at all. He loves the brush and I’m happy the hair is so easy to get out of the brush. One push on the button and you have this tidy rectangle hair. This brush is awkward at first, mainly with the bristles if that’s what you would call them. My boy loves it when I’m using the brush. #RankBoosterReview
