→Distal Limb
In canines the fibula is a fine shaft shape which runs the full length of the tibia. There is an interosseus space between the two bones for the proximal half of the tibia. The proximal element of the fibula that articulates with the tibia has a oval shape and the distal element is a type of compact malleolar bone which interlocks with the distal tibia. This interlocking of the tibia and fibula creates the articular surface corresponding to the '''talus'''.

====Metacarpals and Metatarsals====
The tarsal bones are arranged in three rows moving proximally to distally and seven bones comprise the tarsus. The proximal row of tarsal bones is made up of the two largest bones; the '''talus''' medially and the '''calcaneus''' laterally. In canines the talus articulates with the tibia and fibula proximally and the calcaneus laterally. The calcaneus only has a slight articulation with the fibula. The middle row of tarsal bones is made up of a single bone; the '''central tarsal bone'''. This bone articulates with the tarsal bone proximally and the individual distal tarsal bones. The distal row of tarsal bones is made up of four bones in canines and are numbered one to four in a medial to lateral direction. Each tarsal bone corresponds to a metatarsal except for the most lateral (bone four) which articulates with the calcaneus proximally and the fourth and fifth metatarsals (where a small residual fifth metatarsal exists). The fourth tarsal bone is much larger than the others in canines and and protrudes much deeper into the central space of the tarsus than the other tarsal bones.

The talus has a
The arrangement of the metatarsals are similar to those of the metacarpals in that they are rod shaped bones, numbered from I to V. The 1st is the most medial and is very small, the 3rd and 4th are the longest. The proximal base of each articulates with it's corresponding carpal bone and the adjacent metacarpal. The distal end is its head, which is transversely cylindrical and articulates with the proximal phalanx. Metacarpals II - V possess a sagittal ridge on their palmar aspects.
