The skeletal system is the structural foundation for all vertebrates, including canines. It consists of bones, cartilage, ligaments and tendons. Bone is a versatile biomaterial that serves a multitude of vital functions – it serves as a storehouse for calcium, phosphorus and many other minerals; it functions as factory to manufacture red blood cells and several types of white blood cells (specialized immune cells); it supports and protects the body's vital organs (e.g. a physical cage encases the lungs); it act as mechanical levers to allow muscular action (promotes motion); it provides acid-base balance (helps maintain pH); it detoxifies from toxins (e.g. heavy metals); it helps capture/process sound (via the small bones inside the ears).
Considering all the essential functions of the canine skeletal system, it is imperative to take proactive steps to protect and preserve it with healthy diet and lifestyle practices.
