Dog groomers will use slicker brushes to remove fur mats and tangles from all coat types. Slicker brushes remove dead hairs - both undercoat hairs and the coarser hairs from the outer portion of the dog's coat. Dog groomers will use a slicker brush after using a pin brush and/or undercoat rake to remove a significant portion of the dead undercoat. Slicker brushes are often used as a finishing brush, as the fine wire bristles distribute the natural oils throughout the dog's coat, creating a shiny, smooth finish.
For dogs with a very short, smooth coat, like a Boxer, Amercan Staffordshire Terrier, Miniature Pinscher, Chihuahua (short haired), owners can usually get away with using only a slicker brush or bristle brush for that daily or every-other-day dog brushing.
