it is a dog --4 toenails show in track-- on a coyote usually only the middle 2 toenails show on mud tracks --look it up--I saw it in Outdoor Life years ago in an article showing how differentiate between dog and coyote and wolf tracks .If the outside toenails do show they will be faint. Also coyote tracks are more pointed and dog tracks more rounded.
looks like coyote tracks to me! The four 'finger' prints are round on a cat track
