In some species, hypsodont teeth continue to grow throughout an animal's life (e.g., many species of the rodent subfamily Arvicolinae, family Muridae). In many herbivore species, the forces of almost continuous grazing or rumination leads to dental attrition. In some species, hypsodont teeth continue to grow throughout an animal's life (e.g., many species of the rodent subfamily Arvicolinae, family Muridae). When a dog or cat brings the side of its head up against a bone on which it is gnawing, it is probably using its carnassials. Horses have a combination of brachydont and hypsodont teeth.
