I'll keep my check then.
See how close the two front inside toes are in the top picture? And see how even they are together? Then you drop down a step to the outside two toes. Classic canine. The absence of toenails doesn't mean anything. The PRESENCE of toe nails means something.
Cat toes are spread more evenly in sort of a row. And notice how none of your tracks have the "W" in the rear lobe? They are all just a rounded blob. Classic canine.
But carry on. You asked what I thought. I'll take my half century of tracking cats and dogs and go back to the bank.
