Dog Anatomy Trivia – Built for Running and Sniffing

Dogs share the basic mammal body plan with us but have many special features. They walk on their toes, which helps them run fast, and lack a fully formed collarbone, allowing a long, flexible stride.

Adult dogs have 42 teeth suited to tearing and chewing, and a powerful nose lined with folds for smelling. They have a third eyelid that protects their eyes and around 18 muscles moving each ear. Dogs sweat little and cool down mostly by panting.

Each dog's nose print is unique, like a human fingerprint. Body size varies hugely between breeds, affecting heart rate, lifespan and health. Knowing basic anatomy helps owners spot problems early and care for their dogs.
