For how long? Because I know that my dog stops digging after she get's walked. I take her out to a little river beach a kilometre away with a friend and her Dachshund, and they spend a few minutes swimming and then following us while me and my friend explore. So usually she's out on a walk/adventure for two hours, while walking two kilometres. If that makes sense. I've never seen my dog dig after a walk... does yours run along the fence after a walk? Or is it just before?
