The Chris Christensen Big K brushes were originally designed to fit the specific needs of the Black Russian Terrier; however, it was soon discovered that the brush also worked for dozens of other breeds as well. These amazing brushes detangle and remove knots in half the time of other slicker brushes, and they are ideal for long and hard-to-manage coats.
