I believe it to be a coyote,eastern coyote's get plenty big and that animal while big is not as large as a wolf would likely be.If you look at it's snout it's nose is short like a coyote,a wolfs snout is longer.While I have not seen a black coyote I have friends that have killed completely black one's.I killed one that was completely blond this year.
I am open to being wrong.It just looks like a coyote to me.I have seen and takenseveral of them in New York state.
