Ok, I'll be the first to say it, Bear. I email this pic to a buddy of mine that is a biologist, and deals with bears on a regular basis. He said it was very possible to be a bear track because of the pad area. I little large for a dog. But, it could also be a dog that slid a little in the mud, making the main pad look bigger. So the area you are in, I would say dog, unless there are regular sitings of a bear, probably not going to be one. Also, the toes are a little out of line for a bear as well.
