Wolves are canines (much like their successors, the dog) that prowl the wastelands much as they have done since times immemorial. Wolves have a long history with mankind, and they are still rightly feared across the wastes for preying on lone travelers and exposed livestock.
The wolf is a large canine native to Eurasia and North America.
Before the  Great War, wolves were difficult to tame and frequently lived in the wild. The nuclear holocaust had a limited impact on the species, as they continued to proliferated on both sides of the former  United States.
Although the nuclear fallout had a marginal effect on most wolf populations, isolated groups like the ones inhabiting the wilds of
Mount Desert Island, have steadily succumbed to the twisting influence of radiation and other environmental factors. 
Wolves are quadrupedal canines, much like dogs, and travel in large packs. They are substantially larger and stronger than the common dog and are visually very similar to breeds, such as many sled dogs. Individually they pose a minor threat, but due to their tendency to travel in large packs with their kin, they are still a potential danger. Wolves are one of the few creatures to have been left largely unaffected by
radiation since the Great War and are found commonly in several areas across the continent.
Wolves are dangerous creatures and always travel in large packs of their kin. They easily outmaneuver their enemies and surround them, and lunge at their prey with sharp claws and powerful jaws.
Wolves in the wilds beyond
Far Harbor have been mutated by the radioactive fog and roam in ferocious, bloodthirsty packs. Fast, agile, and highly perceptive, wolves will often notice the player character before they notice them.
Story Time Miss Nanny mentions a wolf during the "Little Red Riding Hood" and "Three Little Pigs" stories that she will recite to the Vault Dweller as part of a random encounter.
