Adrienne,
I have both of them able to stay on command (well most of the time). So I told them to stay in sit position, moved away from them the distance of the leash (6 ft) and said 'come' giving a slight tug on the leash. This provoked the behavior. They definitely reacted to the "resistance". I didn't want to pull hard and drag them. I tried letting them see their treat in my lap and that didn't help, they were to preoccupied tugging against leash. Trying to use recall with the leash because so far they come to recall only when they feel like coming. I have used the treats as recommended to call them but they still are coming only when they want to. I want them to come every time, right! I have really enjoyed your training advice and games and these two love new games.
Thanks - Arthur
