Andy from the coloration, that might be a baby fox. The black legs and ears make me think it might be. Maybe the mother was killed and the little fellow is on his or her own or the mother was somewhere nearby out of sight. I think the babies are more nocturnal this time of year, pretty much stay in the den during the day and only come out with mom at night so who knows. If something did happen to it's mother, it might be worth reporting it to F&G or a rehabilitator to see if it can be captured and saved. Or then again, maybe it is a dog as you suggested, other more knowledgeable people on the site might have a better perspective. Just a thought.
