Are you serious?? Did you click on the link and see the tracks for your self? It is for sure. SO, if you are out scouting and area and see tracks, do you not go back and hunt that area "in case" it is a domestic dog?

If you know what to look for then you would know that it is A. coyote or B. domestic dog.

I suggest you look at that link again and study it.

as far as coyotes using the same path or not, I hunt this piece of powerline, in the snow I find a highway of COYOTE tracks on one side of the powerline. It happens to be the opposite side of where the logs and brush are dumped when the power company trims the trees away. (path of least resistance) If I step, drive my quad or it snows over those tracks, when I come back the tracks are right back in the exact same place until they split of and hunt then regroup on the same pathway.

Again, if you know what to look for then it is a sure thing!
