Watched it five times, and read all the comments.

Sorry folks, that's a raccoon. I'd put my confidence level at 90%. The other 10% is for some kind of canid.

Itdefinitely is notis a mustelid (otter, pine marten, etc.).

That critter has a humped back at all times.Rather un-doglike, and not at all mustelid.A mustelid would only look hump backed at one point in its stride, then the back would flatten out and be low to the ground and elongated. Mustelids move along the ground almost like an INCHworm.

The attitude, quickness of movement is sort of middle-of-the-road. Mustelids look hyperactive, and possums/porcupines look like they are on downers.
