Rick: Sheep tracks are less rounded in shape at the forward edge, and the two toes are more rounded rectangles that are parallel to each other, rather rounding at the front to appear to be coming together. What you put on your knife handle would be a good set of tracks for a standing deer. When they walk, the back foot steps into the impression made by the front foot, leaving a small doubling of the impressions, depending on whether the deer is a buck or a doe. A does leaves a double print with the newer( rear) track on the outside of the track of the front foot. The Bucktrack will be the opposite.
And, then because of eye dominance, the dominant track will have the rear foot stepping about 1/4 to the rear of the front track, so that you have part of the inside or outside of the track, and part of the toe of the front track still showing after the rear foot obliterates the rest of the track. The non-dominant foot will show the rear foot stepping onto the full front impression, showing none of the toes, except the doubling on the inside or outside of the track reflecting sex ID.
