German Shepherds - Illustration of The Teeth

A. Incisors
B. Canines
C. Premolars
D. Molars

Unlike man and other animals, the teeth of the German Shepherd have an unusual feature: the lack of cement on the layer of enamel.
This is why they are always bright white (unless tartar has build up or there are traces of pharmacological substances).
