Sixty percent of the dog's body mass falls on the front legs. [14] The dog has a cardiovascular system. The dog's muscles provide the dog with the ability to jump and leap. Their legs can propel them to leap forward rapidly to chase and overcome prey. They have small, tight feet and walk on their toes (thus having a digitigrade stance and ...

[1] [13] [14] In the dog and horse, the bones of the proximal limbs are oriented vertically, whereas the distal limb structures of the ankle and foot have an angulated orientation. In humans and elephants, a vertical-column orientation of the bones in the limbs and feet is also evident for associated skeletal muscle-tendon units. [6]
Dogs almost always have dewclaws on the inside of the front legs and occasionally also on the hind legs. [1] [3] Unlike front dewclaws, rear dewclaws tend to have little bone or muscle structure in most breeds. It is normal, although not biologically necessary, that certain breeds will have more than one dewclaw on the same paw.
Miller died in 1960, and the first edition of The Anatomy of the Dog was published posthumously in 1964, [1] with George C. Christensen and Howard E. Evans as co-authors. [2] Evans and Christensen also co-authored the second edition, published in 1979, retitled as Miller's Anatomy of the Dog. [3]
Fetlock joint: the joint between the cannon bone and the pastern. Fetlock is the common name in horses, large animals, and sometimes dogs for the metacarpophalangeal and metatarsophalangeal joints (MCPJ and MTPJ).
A dog uses its back to attain speed. The back's most flexible point is just over the loin area, and the tuck-up allows for the folding of the under portion of the dog's body. The rear legs overreach on the outside of the front legs. Essential for a fast dog is the ability to flex its back from a straight position to an arched position.
The three tendons, from front to back, that conjoin to form the pes anserinus come from the sartorius muscle, the gracilis muscle, and the semitendinosus muscle. [1] [2] It inserts onto the proximal anteromedial surface of the tibia. [2] The pes anserinus is around 5 cm below the medial tibial joint line. [2]
