In the last picture to me it seems to have smaller ears in relation to its head than that of a coyote, which I've found are quite pronounced( 1/3 of head length vs maybe 3/4). The snout, while looking tapered thanks to the camera angle, it appears it is still quite stout, thick if you will with a rather large "pad". Just what im seeing. Everything screams wolf to me, they can be tricky for sure, esp once you start getting juveniles and such, but it comes pretty clear when they're side by each. In the flesh, well watching the gut piles out the edge of dads fields ive found they're like looking at grizzlys and black bears, if your guessing it's not a grizzly.
