Some of the coyotes I’ve seen here in Wisconsin are about the same height as a German Shepherd. They’re leaner, but still a formidable animal. 40 lbs would be a good estimate.
And since they are urban, they don’t have much fear of humans, although they are pretty wary of cars.
Im in NE KS, where the average big coyote is 25lbs. they interbreed with dogs I’m sure but wolves no.
