The anatomy of the dog is similar to the inner structure of a human being, although the construction varies very strongly from breed to breed. The dog has powerful muscles, a pulmonary and circulatory system that is designed both for fast sprinting and endurance, and teeth for catching, holding and tearing food. The skeleton inherited from its ancestors provides it with the ability to run with speed and jump far.
Contrary to popular belief, dogs are not colourblind. They can perceive differences, but certain variations cannot be detected, similar to the red-greenblindness experienced by people. On the other hand, dogs have more than 220 million scent-detecting cells, which is four times as many of these cells as human beings have. This is the source of their powerful sense of smell. Dogs arealso capable of a wider range of audible frequencies than we are.
