I’ve read that coyote DNA in the SW have some of the same DNA as did the extinct red wolf. Hybrids between coyotes and feral domestic dogs have no fear of humans and have the hunting instincts of the coyotes. I would be wary of any coyote in daylight because rabies is a real threat and a bite from a wild dog could be lethal. There is not much of a chance of surviving rabies once symptoms develop.
Most canines have 99.9% of the same DNA. From dogs to wolves to coyotes, they all interbreed and produce viable offspring. It is a tiny amount of total DNA that makes the difference between a chihuahua and a wolf. (Or between an African Pigmy and a Scandinavian Viking).
