mine are trained to always stay with us, there are no fully feced area to run dogs around here, and I would say its safe to let claire off if Rebel is fine because dogs stay with the pack, Ripley Runs away all the time you would thing we would never let Ripley off, but we will take all the dogs to an open feild and let them all of to play, they always run way off outa sight but they always come back, and when they come they always get treats for it, just to reinforce the comming back. never had a problem.
