Grey/Timber Wolf - This is the most common breed of wolf and is most numerous. Their coat colors consists of grays, whites, blacks, and occasionally browns. They weigh in the range from 70-135 lbs. They reach sexual maturity at two years and are often driven away from their birth-packs in search for a mate and territory. Once they reach maturity, they tend to live for 6 to 8 years in the wild. Their packs are typically medium, as in about 8 members. Their diet includes deer, caribou, elk, moose, other small mammals, and ocasionally birds.

Red Wolf - This breed of wolf is very scarce in population. They are a rather small, slender, long-legged wolf that resembles a coyote in color but often blackish; typically larger, with a wider nosepad, larger feet and coarser pelage; smaller and more tawny than the grey wolf. They typically way between 40-90 lbs. Their diets contain small deer, other small mammals such as rodents and rabbits.

Maned Wolf - This breed was often described as "a Red Fox on stilts'. They can weigh between 50-55 lbs. The Maned Wolf's fur is reddish brown to golden orange on the sides, with long, black legs and a distinctive black mane. The coat is further marked with a whitish tuft at the tip of the tail and a white "bib" beneath the throat. The mane is erectile, and is typically used to enlarge the wolf's profile when threatened or when displaying aggression. Their diet consists of small to medium prey such as rodents, hares, birds, and fish. They also tend to eat some vegetation such as sugarcane, tubers, and fruit.

Arctic Wolf - This breed is probably the purest of all wolf breeds. They are generally smaller than gray wolves, though they often weigh 100+ lbs. They mostly hunt caribou and musk ox, though they also prey on a number of arctic hares and lemmings as well as other smaller animals.
