What made the following mystery tracks?

These newly found prints measured approximately 8 inches long/4 inches wide and appeared to have only three toes. The individual finding them was quite startled and rain set in before he could get a cast of some sort. But he did take these three photos. The prints appeared overnight, in construction work near a new backyard patio.

For the time being, I am going to leave out the location, and throw the floor open to guesses as to what animal made the tracks (one clear and one partial are visible).
