Ornery little dogs, like Chihuahuas or other small mutts that run around wild in a yard chewing, digging, snarling, and generally destroying whatever they can.
Yard sharks are two or more small dogs that rip across the yards, jumping and snapping, biting, and tearing stuff up, like the shark in Jaws. "Watch out! Lucy and moose are at it again!".
