Well from what i can tell its not a dog . I do have a large BloodHound (130pds) but even her feet aren't that big and the pads on the feet are different then a dogs.
Sorry Flipper but the snow is now melted so i can't get the depth but whatever this paw print is its big.
In parts of Wisconsin Mountain lions have been sighted so maybe theres a big kitty in them there woods .
