Too big to be a coyote. Its very spread out like the animal was carrying alot of weight. Its also in sand though so its hard to tell. I thought a big dog at first, maybe wolf. Depending on what kinda dogs you have its that. If it was a bear cub... wheres mommas tracks? Could be black bear though, I work for michigan DNR. Not in the wild life divison, but I do have common sense in animals. Black bears and wolfs are common in those areas. Go your local DNR if you have any problems with missing cats or dogs.
