Call Bill Murray from Caddyshack. Oh wait, that was a funny looking groundhog.
You need to borrow my parent's dog, Sam. He's a Black Lab mix. He'll lay out by active mole runs and listen, for hours at a time. Next thing you know, he's digging a hole and pulling out a mole. He averages roughly 40-50 moles a year.
Kinda slowing down in his old age, though.
