Big dog, a coyote would have to be HUGE to make a track like that, plus like stated before thery're more diamond shape. Also, coyotes have a very unique way of walking which if you are experienced with seeing the tracks you can tell right away.
Ok, we will chalk it up as a domestic dawg WAY out in the woods. Ill get back out there when it gets above 10!!!!! Maybe i can get a pic of the critter. I appriciate all your responses, even the Yeti Youngling & Ewok ones
