All movements are possible in each region of the vertebral column, with the range of motion determined by disc thickness and articular process geometry. The movements of flexion, extension and lateral flexion involve compression of the intervertebral discs at one edge and stretching at the other.
It is important to note that rawhide bones and chews made in USA are the absolute best for your dog. Choosing American Rawhide, Merrick, Dingo, Bone Buddies or Beafeaters brands you give your pet a rawhide chew of premium beefhide from corn-fed American cattle produced under the strictest quality standards. American production processes and sanitation practices are much better and more highly regulated than most other countries producing rawhide bones.
The safest kind of bone is a raw bone with no sharp edges. There are tons of products in your pet store that are not safe for your dog. Pet toys, bones, etc are entirely unregulated and I will not allow my dogs to chew on most items found in a pet store.utcher shops will sell you raw bones with meat clinging to them inexpensively-they are great for your dog's teeth and very safe. Bully Sticks, Flossies, beef tendons, and deer antlers are other choices that are much safer than the items sold by most pet stores.
