A pet chew toy allowing for the self-cleaning of teeth by domestic pets. The pet toy includes one or more cavities into which a pet's teeth may engage, and the inner and outer surfaces of the cavities may have scrubbing elements designed to enhance removal of plaque and other unhygienic products from a pet's teeth and gums. The chew toy may further include projections to enhance stabilization of the chew toy by the pet, and a reservoir and dispensing system for pet toothpaste or similar additive.
