Thanks Traps,
I agree with bad rep being bs half the time.
I had Rottweilers as a kid, and can vouch for their temperament, as you said, if one sets boundaries and is firm, then they're obedient and controlled (like every dog, I think). Very intellegent, playful monsters.
We had Maltese Poodles that ran the show, and set the rules with the Rotts, so much for the stone cold hardened killers!
They're great guard-dogs, and half the job is intimidation.
This "new, impure" breed you describe, is it an unethical thing to support such a breed, you believe? Do they have known bad traits? Killing off original bloodline?
Must confess, thats the look of dog that appeals to me, didnt know that were not pure.
