In fact I acquired this brush after reading an ad on this article. I thought she was going to be a great help to brush my dog has long hair. In fact I am rather disappointed by this product which is not up to his promises, in fact even if it is intended for more than 5 cm hair, it is not at all suited to a long coat and thick (Pyrenean shepherd dog), the comb does not penetrate deep enough into the fur to remove dead hairs. Parcontre I tried on a dog with hair much shorter and there braque it works well.
