Melanistic coyote?

I'm fairly certain that this recent game gam photo is of a melanistic coyote.
You can see why we've been tempted to buy a new camera with a faster trigger. We get a fairly high percentage of this type of shot (only part of a moving animal).

Here he is going in the opposite direction.

Here's that same photo, lightened up a little.
Without seeing the face, I can't say for sure that it's not a coydog. I don't think those are very common here either, though.
Keep your fingers crossed that we'll get a better photo of this individual in the coming weeks.
