P.S. Forgot to mention, though not a small dog, one of my dogs is white, and if he got too far away from me when it did snow here, I wouldn’t be able to see him! :)
Maybe your dog would go invisible but he’d leave a definite trail.
Snow cuts crime. Last week’s news reported a fellow came home to find his TV had been stolen. He found tracks in the snow and followed them to a neighbor and the TV. Duh!
