HAH, yep. I witnessed some pretty impressive acrobatics when I worked at the dog daycare. I took one glance at that thing and thought, "I hope that dog isn't much of a digger, or a jumper."
Big fan of the electric collar. Has helped me turn my dog from trying to get himself into fights to being very good and obedient.
I forget how rare it is to be in control of your dog any more. I take him off-leash when I exercise him, and the way people look at me, they obviously expect him to come up and just start mauling them and/or their dog because he isn't leashed. It blows their freaking minds that I can throw a ball way out in the water and he'll go get it and bring it back.
