Rather ironic as today I saw very similar tracks but in my case on snow.
Paw prints were somewhat more spaced apart (suggesting whatever was in the12 inch long size) but had that same 'dragging something' appearance.
I was able to determine that whatever critter it had paw 'pads' and fingers like print as the snow left perfect imprints, paws were slightly larger than one inch and clearly indicating a slender animal by the spacing lt/rt.
Now around here they could have been beaver, nope,
raccoon-possible but the 'drag'? nope, besides to early for them to be out.
Otter? don't know
Muskrat? don't think so but maybe.
Porcupine? maybe other than the dragging something.
Also this critter walked down the street and wandering somewhat from side to side.
I'll add that I also observed same style last spring but they were all in straight line following the snow berms.
LOL, the joke might be on me if it was a neighbors dog dragging his leash, but dragging off to one side?
Also the tracks started from the waterfront and onto the roadway, travelled a bit and crossed over to the forest.
Nope, I wont set up a webcam but perhaps take my camera to capture the tracks.
Problem might be definition of white prints on white snow.
