Which animals chew with side to side mouth movements?

Herbivores chew with side to side mouth movements and back to front mouth movements, called grinding. 

An herbivorous animal eats plants, such as grass, leaves, fruit, bark, and flowers.

Herbivores have blunt-shaped teeth called molars. Their canine teeth are reduced or non-existent. 

Herbivores have different chewing movements than carnivores.

Carnivores eat meat and therefore they have sharp canine teeth as well as molars. Carnivores chew with up and down mouth movements, called chomping.
