PATHOLOGY

Detailed explanation-1: -Most herbivores are missing canines entirely, and those that do possess them usually have very small or reduced canines that are not very important for chewing food. Some herbivores have large incisors for clipping or tearing vegetation, but they may only occur on the lower jaw.

Detailed explanation-2: -Rodents lack canines. The tusks of wild boar, walrus, and the extinct sabre-toothed cat are enlarged canines. (The tusks of elephants are upper incisors, not canine teeth.

Detailed explanation-3: -Not only do most mammals, including herbivores, have canine teeth; but the largest canine teeth of any land mammal belong to a true herbivore: the hippopotamus.
