In addition, you will find paired articular processes at both the cranial and caudal surfaces of a dog vertebra, at the junction of pedicle and lamina. Again, the transverse process projects laterally from the region where the pedicle joins the vertebral body. The dorsal part of the arch forms the single spinous process at the middorsal aspect of the dog vertebra. The spinal nerves, arteries, and veins pass through the intervertebral foramina of a dog. So, the adjacent vertebrae also form intervertebral foramina. You will find cranial and caudal vertebral notches on either side of the pedicle of a dog vertebra. All the vertebral foramina concur to form the vertebral canal that contains the spinal cord and roots of the spinal nerves of the dog. Together with the body, the arch of dog vertebrae forms a short tube (vertebral foramen). There are two parts in the dog intervertebral disc – the gel-like nucleus pulposa and annulus fibrosus. You will also find an intervertebral disc between the adjacent vertebrae of a dog. And form a vertebral column along the midline of the body. The adjacent vertebrae of the dog articulate together with the help of ligaments, muscles. You will find the same structures in the dog vertebrae like body, arch (pedicle, laminae), and different processes as found in an ox or goat. I think you have a good piece of knowledge on the typical vertebrae of animals. Ensure you know the name and numbers of vertebrae in the different regions of a dog spine (mentioned earlier). Here, I will try to provide all the information on dog vertebrae with the labeled diagram. So, the main part of the dog spine anatomy is the vertebra. You will find a variation in the number of caudal vertebrae in a different breed of dog. The number of caudal vertebrae is not fixed in a dog skeleton.
