No hawgs that I know of.
The print is about 2-1/2" to 3" in diameter. It's the size of a large dog. It's got the array of round'ish pads around a larger central rear pad and claws at the ends of the exterior pads...again, like a dog.
Man, it's alot of digging. Some of the damage is not a trench as much as moving laterally along the shore at the waterline for 3 or 4 feet.
If/when we get the back hoe out for the garage project, I'll probably have him dip into the pond (in front of each hole) and scoop out a hefty wet pile of soil and drop/pack it into each hole.
