Man you guys have some terrorists on your hands!.. My guy wouldnt dream of disobeying his master!
I haven't had a problem since. Granted, took a couple of incidents and subsequent "behavioral training" I was talking about, but Quatro and Westside now know who's boss. Also, Dogproofing the home helped a lot too.
I also find running them like crazy a couple of times a week (at a minimum) keeps their destructive tendencies in check.
