Common Features of the Dog Group

Dogs resemble wolves other more than any animal. Wolves are distributed mainly in the Northern Hemisphere: Europe,   North   America, and Asia.

 Generally, those inhabiting the colder climates are larger, lighter in color (probably for protection).

More aggressive,  while those found in warmer regions are smaller, with a yellowish fawn coloring that becomes lighter towards the abdomen, and are less aggressive.

This latter coloring is the one most often seen in the domestic dog. Although wolves are often believed to be enemies of humans, in reality the opposite is more often true; they very rarely attack, but rather easily become accustomed to people.
