I wouldn't buy a dog from a Schutzhund breeder myself, but sharp is one thing and unprovoked aggression is another. Certainly those dogs would tend that way though.

They do... And they take real training and conditioning to be good in a home. I know a local Schutzhund guy and I absolutely am awestruck by his dogs. I'd love to have one, and I love watching the sport. But I wouldn't work with just any trainer, only him. There's a fine line between training an effective protection dog and just ending up with one that only protects himself.

Someday maybe.

I can see an analogy to the really high high energy dogs like Border Collies (or my Lab who takes after her field trial side). If these dogs don't get the proper training, they are absolutely uncontrollable.

I have been on my dog like white on rice since we got her at 12 weeks. She is always in training and that keeps her within the bounds of reason - if she were not properly trained she would be unbearable.
