The dogs skeleton serves as the structural framework for support and protection of the body. Along with muscles, the skeleton enables the dog to stand, sit, run, and walk.
Bones are hollow tubes made up of hard, latticed structures called trabeculae and are filled with bone marrow. Bones are nourished by blood vessels that enter them through small holes called nutrient foramina. Unlike humans, dogs do not have a collarbone; their forelimbs are held together by only the muscles. This allows dogs to have great flexibility in movement.
All dogs have 30 true vertebrae, plus a varying number found in the tail. The vertebrae are arranged in 5 groups: 7 cervical, 13 thoracic, 7 lumbar, 3 sacral, and the varying number of caudal (tail) vertebrae. The spinal cord lies within the vertebral canal in the spine for protection.
The canine skull comes in three basic shapes. The dolichocephalic shape, as seen in the Afghan Hound, is elongated and narrow. Short, broad heads, like that of the Bulldog, are called brachycephalic. Skulls of average length, like that of the Siberian Husky, are classified as mesocephalic.

The Best Dog Breed Book,
By
Amazon Verified Purchase(What's this?)
This review is from: Dog Breeds: An Illustrated Guide (Paperback)
I initially saw this book at my Veterinarian's office in San Diego and was very impressed by it. I took down the publisher's name and address
During my last visit there with my two Keeshonden, I was disappointed to learn that it had been thrown away due to other customers' overuse/abuse?! The Vet Techs also said that when they tried to reorder it, they learned that it had been discontinued. Utilizing my previous information, I tracked it down to Amazon and was delighted to be able to order it at a really good price. This beautifully drawn and printed book now resides on my family room cocktail table to be enjoyed by all my guests. Thank you Amazon. John Eric "Rick" Paulson San Diego, CA
