Body Parts of Dog

By Savannah Groeneveld
Man’s best friend is more than just a furry, licking machine. Dogs are actually comprised of many complex systems that all work together to make your dog the happy, loving pet that it is.

Circulatory System

A dog’s circulatory system is very similar to a human’s. Both have major arteries, smaller veins, capillaries and a heart to pump blood all through the body.

Special Sensory System

Dogs are well known for their incredible sense of hearing and smell. The shape and organs of the dog’s ear allows them to hear in frequencies far beyond the capability of humans. A dog’s sense of smell allows him to hunt and identify other animals.

The Digestive System

Like most mammals, the dog’s digestive system begins in the mouth where the teeth and tongue do the work of shredding and tearing the food. Unlike humans, dogs do not have an enzyme in their saliva that breaks down the food. The rest of the digestive process is pretty much the same as in people.

Dog Hair

The primary purpose of a dog's hair (coat) is the insulation that it provides to the dog's body, k eeping it warm in the winter and cool in the summer.

Significance of Anatomy

Multiple body parts, unique to the dog species, have evolved to aid it in survival.
