First pic looks like the long hind pad of raccoon. Second looks like rabbit and maybe prairie dog. Third is a rabbit moving away and some guy with big feet. My guess is the dog tracks are coyote from the length of the stride. Put four together and you have the approximate length of the animal. Fox stride is somewhat smaller.

This morning I'm seeing tracks of rabbit, coyote, a large feral cat and Gambel's Quail.
