Id say Wolf, look at how wide his shoulders and head are. Coyotes are a little more slender and not as bulky/muscular.
I dont see wolves breeding with coyotes, unless perhaps a male coyote gets a young wolf female. I had a professor that did his doctorate studies in Yellowstone on wolves and say they are mortal enemies. Wolves will kill coyotes for no reason and leave there body to rot.
