And it would definitely take the right dog to make the cross. Your backyard bred dog aint gonna get it done. People who are serious about their GSDs or Mals cull every bit as hard hunters do to get what they want.I am not as knowledgeable in the Malinois blood as I am the GSD's. But if crossed with a GSD it would definitely have to be out of some old Czech blood for me. Either dog, I wouldnt look for so much a breeder who breeds for schutzhund, but rather a breeder who breeds specifically for police K9 or personal protection dogs. Like someone said a lot of the ring sport dogs never take a real beating, but I have seen some protection dogs take some good beatings and it only seemed to turn them on more.
They cull alot harder from what I have seen.
There is a guy in NY or somewhere in one of those yankee states that breeds some unpapered dogs that he sells to special forces, I cant recall the guys name, just remember the conversation from a day at training. From what I understand this guys breeds, raises, and trains some crazy dogs that would probably fit the bill of what your looking for.
