Yes...pulling forward, like pulling a boat line, or a cart. We have a rope from our boat, which she plays tug with. If we toss it, she will retrieve the rope and push one end into our hands (or bump us in the knees with it, until we take hold)...then she will pull backward on it.
Just wondering if there's anything special we're supposed to do, to train her to pull forward (like pulling a cart or swimming a boat to shore).
