Dog paw. The paw of the dog has a digitigrade orientation. The vertical columnar orientation of the proximal bones of the limbs, which articulate with distal foot structures that are arranged in quasi-vertical columnar orientation, is well-aligned to transmit loadings during weight-bearing contact of the skeleton with the ground.
The dog has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. [5] Dog breeds vary widely in shape, size, and color. They have identical skeletal structures (with the exception of the tail and skull), powerful jaws that house around 42 teeth, and well-developed senses of smell, hearing and ...
Canidae (/ ˈkænɪdiː /; [3] from Latin, canis, "dog") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid (/ ˈkeɪnɪd /). [4] The family includes three subfamilies: the Caninae, and the extinct Borophaginae and Hesperocyoninae. [5]
Comparative anatomy studies similarities and differences in organisms. The image shows homologous bones in the upper limb of various vertebrates. Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny [ 1 ] (the evolution of species).

Stifle joint. This dog's stifle joint is labeled 12. The stifle joint (often simply stifle) is a complex joint in the hind limbs of quadruped mammals such as the sheep, horse or dog. It is the equivalent of the human knee and is often the largest synovial joint in the animal's body. The stifle joint joins three bones: the femur, patella, and tibia.
The terms tarsus and hock refer to the region between the gaskin (crus) and cannon regions (metatarsus), which includes the bones, joints, and soft tissues of the area. [2] The hock is especially important in equine anatomy, due to the great strain it receives when the horse is worked. Jumping, quick turns or stops, and movements that require ...
The phalanges are the bones that make up the fingers of the hand and the toes of the foot. There are 56 phalanges in the human body, with fourteen on each hand and foot. Three phalanges are present on each finger and toe, with the exception of the thumb and big toe, which possess only two. The middle and far phalanges of the fourth and ...
