ok so here's another ... this one shows jack TELLING me to throw the ball for him. It also displays my biggest mistake in training him, allowing him to get like this. I've done a lot of work since and reduced his carry on but i've never completely gotten in control of it.
p.s although his barking looks and sounds aggressive, i would be more than happy for any person(adult or child) to go up and pat him while he's carrying on.
ETA : the patting him while he's carrying on about his ball has been tested by strangers, the worst that might happen is a kid pick up his ball and jack will jump up on them and bowl them over trying to get his ball(has actually happened with my nephew)
