To groom a horse's coat using a curry comb. The comb itself is a round or rectangular tool usually made of rubber or plastic.
It has stubby, semi-pointed "teeth" that serve to loosen dirt, hair, and dander for later removal with brushes.
It also is used to remove hard-packed dirt and debris from the coat, stimulating oil glands; thus, it is a vital part of grooming for a healthy coat.
A curry comb is applied with a vigorous, circular rubbing motion.
