  • Patent number: 7621234
    Abstract: A brush that is adapted to remove hair from a domestic animal, such as a dog or cat. The brush includes a rotatable bristle pad having a plurality of bristles for removal of loose hair from the animal. A cleaning comb is disposed proximal to the bristles such that the cleaning comb overlaps the bristles to remove hair from within the bristles during use. The removal of hair from within the bristles advantageously reduces clogging of the bristles and maintains the ability of the bristles to remove additional hair.
