Dogs cannot survive in the wild because they have pups at all times of the year.

I am no expert on dogs but I think you're wrong here. I seem to remember that female dogs come into heat only once or twice a year.

Hmmm, I re=read what you wrote and it’s different from the first reading. Yes, it is quite possible that female dogs can come into heat at different times of the year as opposed to wolves, who may synchronize their pup-bearing. Sorry.

Wolf or coyote? Genetics tell complicated tale

"...So, the coyotes that arrived in St. Lawrence County in the 1930s were already an altered species."

"Trappers back then called them coy-dogs, and the name stuck; however, today we know you really can't have a self-sustaining coyote-dog hybrid out there because, for one, dogs breed at all times of the year, and pups born in January or February would have little chance of surviving. Also, if dog genes were an important component, we would have coyotes of all shapes, sizes and colors."
