I highly suspect there are wolves in the lower peninsula. They were introduced in the upper peninsula and have established packs there. Twenty-some years ago, there were reports of cougars in the lower peninsula. People even had trail cam pictures, but the DNR denied their presence until a study proved they were there. Even then they claimed there were some that wandered into the state, but there wasn't a breeding population.
Now, back then, when I was looking into cougars, I found unofficial reports of wolf dens just south of the straits in the northern lower. There was speculation they were traveling south in the winter over the ice sheets. The coyotes are hybrid and if there are a few larger ones, I can believe it may be a coyote, but I can't rule out a wolf. Normally, if I found such a track on the road, I think a domestic dog was on the loose. In this case, on the main trail, maybe a domestic dog, but on the feed pile, that makes me think it's a wild dog of some kind: feral domestic, coy-dog hybrid, or a gray wolf.

A trail goes two ways and looks different in each direction - There is no such thing as a timid woodland creature - Whatever does not kill you leaves you a survivor - Jesus is NOT a bad word - MSB
