White Bigfoot or Patchy Ungulate?

An rough animated dark-headed ungulate with the foreground legs white. It creates a similar shape
 and gait to the alleged light-colored Bigfoot in the MK's video analysis.

We did the rough animation above after seeing MK Davis's video at Bigfoot Evidence. The video M.K. Davis released shows a possible light-colored Bigfoot. The gait to us looks like gallop with half the information missing, as if the legs in the background are dark. Dark enough to blend into the background. In MK's Video we see a leading head that seems darker than the rest of the body.

This would also take into account two distinct moments MK points out; the hind legs kicking up, and the portion MK refers to as the "big step".

Our crude animation placed on top of MK's isolated GIF. The part MK has
 isolated is too close to a tree and may hide any suggestion of a head.

Its all very hard to determine, but the white blob in our animation looks similar to the movement in the video to us. We would love to hear what you think. Please, feel free to shoot holes into our theory in the comments below. Obviously we always want it to be Bigfoot, but we see a gallop happening, not a bipedal gait. We have contacted MK Davis and asked him to weigh in.

Here is MK's video analysis below.
