I would say wolf, because it seems like its got a big shoulder mass, maybe used for bringing down larger prey. Or maybe its a dog that got caught in mid-stride and it just seems that way. Would kinda have to know if you have neighbors, or whats around that land, to know if its a dog. Wouldn't doubt it if it actually was a dog, but whatever. I voted wolf. Kinda cool you had one of them wander past your cam.
