You better check those tracks real close, fox only den when they have pups and they are starting to mate at this time of year, in the rare ocasion they will go in a hole if it's really really cold, fox sleep in the open fields, fox tracks and coyote are very similar and if you follow these tracks a way from these holes a short ways there is no mistaking a wild canine, one print directly in front of the other, the wild canines differ from a dog , the dog's tracks are splayed out round more like a cat and they don't put one foot in front of the other, the fox and coyote are more narrow and the three main toes make a point not spread out like a dog, a cat track also makes one foot in front of the other but if you look close you will see the roundness to it . these holes you see are ground hog holes that other things use as a den, ****, skunk, wild feral cats, possum are some that do.
like I said above the best way to tell a wild canine is that they walk one foot directly in front of the other about 12 to 18 inchs apart depending which, coyote the longer step but it is always a straight line like they were walking on a tight rope.
