Thanks, interesting read. I've seen "coyotes" with floppy ears, short hair and large sized. Maybe more feral dog but acted like a coyote nose down on the trail running in to my turkey call. Checked to see if it had a collar one. I see coyote variation in north Durham region, some are the typical smaller shaggy fur grey color with pointy noses. A few were large german shepherd sized more wolf like, one of the large ones was jet black. All stayed away but none ran away like their life depended on it.
