The tarsus or collection of bones of the hind leg forming the joint between the second thigh and the metatarsus similar to the ankle in humans.

The joint on the hind limb, or leg, located between the lower thigh and the rear pastern.

A dog walks on its toes like a horse, not the soles of his feet like a bear or a human. The human wrist is analogous to the canine pastern joint, the back of the hand is the dog's pastern, and the fingers form the dog's paws.
