Oh no, I hope we arent going to get started with the old coydog thing now, lol. Superior predators normally drive away or kill the competition, so coyotes moving into a new area may initially cross with a free roaming or wild dog but are more likely to kill it. Once the coyotes are established, cross breeding seldom continues. Plus, domestic dog cycles often puts offspring on the ground at the wrong time of the year, etc. Dont underestimate the size of northwest coyotes! I mean north, not just our northern states. The eastern coyote is in a league all its own, though.
