Wolf Pup Physical & Social Development. Wolves live in diverse and changing environments. Preparation and care of pups is fairly consistent around the world as is pup development. The following timeline provides information on the development of various physical and behavioral tools that wolves have for survival.
Cousin to the dog, the gray wolf is a highly social animal, preferring to live in packs. The pack, dominated by a male/female pair, may include their pups of the year, wolves born the previous year, and other adults. Gray wolves may be shades of gray, brown, black, or white. Wolves of all these colors roam the Refuge.

Red Fox. Red fox, Vulpes vulpes, is a type of true foxes living in the Northern hemisphere. The importance of red foxes is high, as they are the most widely spread and the largest true fox species. Their natural distribution ranges in North America, Europe, Asia, and some Northern Africa.
Adult coyotes are more than double the size of gray foxes, and coyotes in the eastern US tend to be bigger than those in the west. Evidence suggests that the coyote interbred with the eastern Canadian wolf as it spread into the northeast in the past century.
