Schutzhund is a sport like any other. The bite is the last thing you train not the first. Basic obedience is a must and OUT is trained well first too. Here is another excellent working dog. Please watch this video. NOTE the dog Drop in a second and redirect.I disagree. But I'm admittedly not well informed about this kind of stuff.
Why would you train a small, hyper breed to do schutzhund when it isn't really suited to that kind of work? That seems very dangerous for people around the dog...and eventually for the dog because if he bites someone, he's dead.
Is it cute? Sure.
Is it smart? I don't think so.
Porter was an amazing working dog. This is what the sport is all about.
This dog stoped in mid "attack mode" and was able to redirect. This is not something that can happen with a dog that is in any way unstable.
