The Domestic Dog
The Gray Fox
Gray wolves range in size from 4 to 6 1/2 feet, including the tail.
The fur of the gray wolf can be whitish, gray, brown, sandy yellow, or black.
The wolf is the largest of the wild canids. It lives and hunts in a family group, or pack. The wolfis the most social of all the carnivores. A pack may range in size from five to twenty dogs, and is led by the strongest male and his mate.
There are two existing wolf species: the gray, or timber, wolf (Canis lupus), and the red wolf (Canis rufus). The gray wolf is more common and can be found in many parts of North America, Europe and Asia. The red wolf is slightly smaller than the gray wolf. It is extinct in the wild and can be found only in managed wildlife refuges in the southeastern United States.
