Why do Dogs Like Bones

Every dog owner must have gazed in wonder at the dog chewing
blissfully at its bone. For a canine, nothing can be a better sedative. It is
strange that a dog will continue to chew the bone even if there is no meat on
the bone. It not only chews it but also crushes it. The end of the meal will
see most of the bone disappearing within its body. It is puzzling to see that
an animal loves a thing which has zero nutrition value. The dog loves the bone
so much that it can spend hours consuming it.

Fat is important

The answer lies in the annals of history when humans first
domesticated dogs. The clue lies in the sites located in New Mexico where bison
bones were discovered. The bisons concerned was hunted down around 1450 AD. The
hunters, the archaeologists discovered, left the female bison alone but took
away the meat of the male bison. A little more investigation found out that the
kill happened not during the winter time-the customary bison hunting season,
but during the spring. Female animals killed during spring does not taste well
as the fat content in their body is found to be less. The female bison was
probably pregnant and severely stressed resulting in a lower quantity of fat in
the body. The herbivores live off their fat reserves, and the fat content of
both male and females are much reduced. A diet consisting of only protein for
predators is inadequate for the calories needed to sustain the body. There is
also the chance of protein poisoning. This is why the hunters took away the
male bison’s meat and not the female herbivore’s.

Bone marrow helps to survive All of these leads us to
the answer of why dogs love to chew on bones. The changes in season affect the
ready availability of plants and vegetables which are eaten as food by
herbivores. The latter in turn are prey to carnivores. Bones are essentially
fat reservoirs. The marrow of the bone is rich in fat, and this keeps the
animal alive at a time when there is a lack of food. Bone marrows are nearly 50
percent fat in composition. There is also the presence of bone grease, the
chemical which bonds the essential calcium to the bone. For a predator who
caught its prey at a particularly bad time of the year, then the bone marrow
becomes an invaluable fat source. This fat literally multiples the nutrition
capability of the prey. For a carnivorous animal like a dog, the bone grease,
to its genes, make the bridge connecting life and death. You should always give
the raw bone to your dog and not a cooked one with no fat.
