The Coywolf Is Part Dog, Part Wolf, Part Coyote

Unusual blending of two species that have shared territory for a very long time.

Promiscuous little cuss …

I'm aware that it can happen, but I am skeptical of it being very widespread once the coyote population stabilized, as in gets high enough that there are breeding age males for every female. I wouldn't think it is a stable crossbreed simply because coyotes raise their young as a mated pair, male domestic dogs don't.
In the Midwest, Appalachia and the South, there is more and more evidence that the local coyotes are hybrids between the Algonquin Wolf and the Coyote. The Algonquin, Red Wolf and Coyote are closely related and seem to interbreed. The local coyotes are fairly large compared to out west, a 70 lb. dog is not unusual. I can't think of any time out West that I ever saw coyotes in a group large than a pair, I have seen packs of 5 or 6 around here.
