Northwestern wolves are one of the largest subspecies of wolves. In British Columbia, Canada, five adult females averaged 42.5 kg or 93.6 lbs with a range of 85 lbs to 100 lbs (38.6 - 45.4 kg) and ten adult males averaged 112.2 lbs or 51.7 kg with a range of 105 lbs to 135 lbs (47.6 - 61.2 kg), with a weight range for all adults of 38.6 kg to 61.2 kg (85 – 135 lbs).

In 1993, a study proposed that the wolves of North America display skull traits more similar to the coyote than wolves from Eurasia. [56] In 2010, a study found that the coyote was a basal member of the clade that included the Tibetan wolf , the domestic dog , the Mongolian wolf and the Eurasian wolf , with the Tibetan wolf diverging early from ...
