Okay, the neighbors are thinking about getting rid of their great dane because "he's stupid as a rock". The dog isn't stupid, he just hasn't been given a fair shot at training. Long story short, I offered to work him while I'm outside working my dogs. My only delima is this.... Training the heeling. This dang dogs back is as tall as my third rib and is probably as long as I am tall (5'2). I need some advise on physically how to show this dog that he needs to end up at my left leg because my arms are only 2 ft long to lure him with treats.
