Ours are. We have Coyotes that are the size of large dogs. I've seen some that I thought were red Huskies but they were large Coyotes. I'm guessing they weigh 50lbs or more. I have two part Yellow Mountain Curs that weigh 60lbs and the Coyotes appear to be as big as the Curs are. Ours also hunt in packs and make a terrible racket when they are hunting. So far they have never attacked a human but they don't seem to be afraid either. A lot of the Eastern Coyotes are very large and hunt in packs like wolves. I know they do because I've seen them.
I hear ‘em running the deer at night through my woods. Siberian Huskies (aka domesticated Russian Wolves) are often mistaken for our coyotes - (I have small breed dog - pure bred that goes straight back 4,000 years - bred to hunt small game in the brush. Except for his predominantly black color and smaller size, has this same profile. Beautiful animals.
