The Dog as a Carnivore
Herbivores show highly adapted digestive tracts but the digestive system of carnivores shows no specific adaptations (when compared to that of an omnivore such as a human)The adaptations are found in other structures
Many of these adaptations are associated with hunting:
- eyes are set at the front giving stereoscopic vision
- the ability to run fast
- camouflage colouring
- powerful claws for gripping prey
The most important adaptation (for our purposes) is dentition
Canine dentition:
- 12 incisors
- 4 canines
- 16 premolars
- 10 molars

The incisors are sharp; enabling the gripping of preyThe canines are large and sharp; again this facilitates the gripping of prey and also allows flesh to be torn off
There are actually more premolars and molars in dogs than in cows but in dogs these teeth are smaller and more pointed than in cows - they are thus adapted more for ripping flesh than grinding food
