RE: Coyote or fox?
The underside of the tail is white tho. How many fox have white under their tails? And it doesn't look long enough or thick (bushy) enought to be neither a fox or coyote.
I think it's a deer, but a smaller one, although not a fawn. That tail just looks too deer-like to me. If it weren't for the tail, I'd guess coyote, but I really believe it's a deer.
