My 6 month old Gidget has decided that she needs to sneak out the door and run, run, run. She does not listen when you call her. She'll stop running for a minute look at you and start running again. My other yorkie I let out to go potty and he comes when I call not her. I do tie her out. We live in amish country so I'm not worried about traffic but I need to train her to listen and not run out of the yard. My other yorkie was never like this. She is so bad
