The pin brush is a very common all round brush when it comes to getting out minor mats and tangles from medium-to-long-haired dogs. They have rubber or plastic tips on them and are gentle on thick or curly coats, which is why many use these as a first resort for minor knots and mats. They are generally quite kind to your dog’s skin and are safe to use on most breeds. The pins do not have blades and so do not cut the fur (which could result in damaging the coat).
