Animal Tracks

It rained here for a couple of days, so the ground is very muddy right now. Thats bad for me to have to walk in, but good that I get to see all kinds of tracks in the mud. Most are cow/calf tracks but every once in a while I get to see others. I am posting pictures of the tracks I saw this morning to see if you can identify what animal it came from. Look closely and then tell me what you think made them. In the first picture there are dog tracks, my footprint, and the one I want you to identify, I cropped it to show just track I want you to see in the second picture.
