A device for cleaning the teeth of a dog or other animal has a core element having a plurality of brushes extending therefrom and a compressible hollow outer shell having a plurality of holes, each of which is aligned with a respective one of the plurality of brushes, so that the brushes are exposed. When the animal bites against the shell, the shell is compressed, in turn causing the brushes to further protrude from the shell and exert a cleaning effect on the animal's teeth.
