Yorkies were originally bred to control the rat population so yes, they are hunters. I really don't think it's necessary to use a tie out to control the hunter instinct. As for the hawks, they make me nervous but I'm sure they are more interested in the chipmunks, squirrels and bunnies. Speaking of bunnies....that's the prey of choice for Pebbles and Doodlebug. Let's just say there have been times that they have come into the yard never to make it back out.
