Hog track.

If it were a deer, the dew claws should be more in line behind the hoof. Deer tracks are symmetrical. If you can draw an imaginary line between the hoof, and the sides mirror each other, it is probably a deer. The toes on a buck run parallel, while the toes on doe curve inward at the front, almost forming a heart shape. The impression left by the toes on a deer track are often longer than they are wide.

With a hog track, you cannot draw any lines of symmetry. Sometimes, they have dew claws back kind of like a deers, but most of the times, they are out to the side. The two toes are not symmetrical, and often the dew claws are not. As hogs grow, the differences between the two toes become more pronounced. Young hogs toes will run almost parallel, but as the hog grows, they will start to point out. The impression left by the toes on a hog track are often nearly as wide as they are long, as are the tracks of most domestic animals.
