The behavior of canines engaging with skeletal remains is rooted in instinct and serves several purposes. This activity, common across many dog breeds, extends beyond simple amusement; it satisfies inherent drives linked to nutrition, dental health, and mental stimulation. The act involves repetitive chewing and manipulation of the object.
Historically, for wild canids, consuming every part of prey was vital for survival. Bone marrow is a rich source of fat and nutrients, representing a valuable energy source. The physical action of gnawing helps maintain dental hygiene by scraping away plaque and tartar buildup, contributing to healthier teeth and gums. Furthermore, the persistent engagement can alleviate boredom and prevent destructive behaviors, providing a constructive outlet for pent-up energy.
