Although this brush also includes "pins", it's the shape that makes it in a class of its own. The fine wire bristles and wide frame easily remove dead hair, mats, and tangles. It's important to gently use this brush in the direction of hair's growth because some pups consider this a tad prickly.

Dogs with short, wiry coats like terriers as well as pups with harsh, outer coats and soft undercoats (collies, sheepdogs, chows) can benefit from some slicker action. For those double-coated pups, you can then brush against the grain to get at that second layer. There's even versions for kitties!
