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).

The most genetically basal coyote mDNA clade pre-dates the Last Glacial Maximum and is a haplotype that can only be found in the Eastern wolf. This implies that the large, wolf-like Pleistocene coyote was the ancestor of the Eastern wolf. Further, another ancient haplotype detected in the Eastern wolf can be found only in the Mexican wolf.
