Ours (all 4 of them) only go in the back yard. We keep the front yard looking nice, and let the fur babies have the 2 acres in the back. I guess with it being so spread out, there's not too much of a problem. They find a new spot every day to "explore." I put black pepper in their favorite holes. They've decided all holes don't smell good and make them sneeze, so they don't dig any more.
