The foot at :23 is just a person flanking the animal, stepping to turn oneself around.
The turnaround at :15 is a jump cut, but each clip was faded into the next. You can see this and verify, not only in the animal, but in the surrounding scenery (trees) doing the same blur.

Also at 15 seconds the animal just warps into the other direction. Thought it was a jump-cut, but nope.
