Yeah. That's pretty amazing. Once there is a ball in play that is all Buffy thinks about. One of these days maybe I will try doing some impulse control on her. That is so cool to see and very useful for safety as well.
My first dog, Abigail, had great long distance control and would sit or lie down wherever she was. She didn't need a leash at all. She never had formal training, this was just based on what I taught her when I was 12 or so. Somehow Buffy doesn't have that same control. This might inspire me to work with her on it! Any tips on teaching that long-distance sit and down?
Justice is such a great dog. Congrats on all the work you have done with him.
