Okay, first, let’s know some of the essential osteological features of the dog hip bones. Then we will learn the details of the ilium, ischium, and pubis bones in details. Peroneus longus: originates on both the tibia and fibula and inserts on the 4th tarsal bone and the plantar aspect of the metatarsals. It acts to flex the tarsus and rotate the paw medially. It is innervated by the peroneal nerve.

Descending superficial pectoral: originates on the first sternebrae and inserts on the greater tubercle of the humerus. It both adducts the limb and also prevents the limb from being abducted during weight bearing. It is innervated by the cranial pectoral nerves. The calcaneus (fibular tarsal bone) is the largest and longest bone in the dog tarsus. You will find the central tarsus of the dog hind paw that lies in the medial part of the tarsus between the proximal and distal rows. So, these are some of the specific osteological features of the dog vertebrae. But, this information is not enough to learn the anatomy of the dog vertebrae. Cervical vertebrae of dog skeleton There are typically five metacarpal bones present in the forepaw of a dog. Each metacarpal bones of the dog are cylindrical shaped and enlarged at both ends. You will find a base (proximal), body (middle), and head (distal) in a dog metacarpal bone.Middle gluteal: originates on the ilium and inserts on the greater trochanter. It acts to abduct the hip and rotate the pelvic limb medially. It is innervated by the cranial gluteal nerve. What is interesting is how different shapes and sizes can be a factor in behavior, especially that brachy breeds tend to show more interest in humans and dolicocephalic breeds are less easily startled and also how different breeds have more fast twitch muscle fibers than others. At the bottom of the uterus is the cervix, which leads to the vagina. The vulva protects the entrance to the vagina. Teres minor: originates on the infra glenoid tubercle on the scapula and inserts on the teres minor tuberosity of the humerus. It acts to flex the shoulder and rotate the arm laterally. It is innervated by the axillary nerve.

Paw pads are crucial for cushioning of the bones, providing traction and abrasion resistance. If there is trauma or injury to any one of the pads, it can often result in loss of limb function. Anna A. Kasparson; Jason Badridze; Vadim V. Maximov (July 2013). "Colour cues proved to be more informative for dogs than brightness". Proceedings of the Royal Society B: Biological Sciences. 280 (1766): 20131356. doi: 10.1098/rspb.2013.1356. PMC 3730601. PMID 23864600. There are also lateral and medial intercondylar tubercles on the intercondylar eminence of the dog tibia. The popliteal notch locates caudally in between the lateral and medial condyles. A prominent tibia tuberosity is present in the proximal end of the dog tibia bone.

Now, I will show you all the bones from a dog’s different pelvic limb segments with their specific osteological features. Hip bone anatomy from the dog skeleton Spine: A bony ridge that divides the lateral surface of this bone into the supraspinous and infraspinous fossae. If you want to learn the anatomical facts of the tibia and fibula bone in detail, you may read the previous article from the anatomy learner. You will find more tibia bone labeled diagrams and videos in that article.

The distal extremity of the dog femur is quadrangular and possess the three main articular surface. You will find an articular surface on the lateral and medial condyles. Again, an articular surface is present in the cranial part of the trochlea.

You will find seven cervicals, thirteen thoracic, seven lumbar, three sacral, and eighteen to twenty-five caudal vertebrae in the vertebral dog column

A lurcher will have more fast twitch (anaerobic) fibers in their legs than the Alaskan Malamute who has more slow twitch (aerobic) fibers. Klaus-Dieter Budras (7 December 2010).
