They're called coydogs here in Vermont, though they aren't very large part dog, compared to wolf, according to that study. I hear them fairly often at night, but only seen one, soon after sunrise beside the road when I was driving. It did look bigger than a coyote and not as sharp faced, wolf like, though not as large as a wolf either. There's an interesting side by side comparison of skulls of western and eastern coyotes (or coydogs, coywolves or whatever you want to call them) on Wikipedia. Quite a bit more powerful skull with much larger canines:

Glad you bring up coydog. I think that really must be more of what they are.
In my thinking---- With out having wolves in the states for 100 yrs or so,
How could wolves add additional dna to the mix? Not just that but both
coyotes and dogs contain plenty wolf dna from scratch.
Either the paper is typical sensationalism. Or wolves are sneaking around
Boston and NYC un- noticed?
Perhaps the federal government is sneaking wolves back into the forests
like they have done with Puma?
