Dani, If you mean that you should not let someone you think might be a bad guy get that close to you. I would agree. But if you are saying a real dog should not be under that much control, I would have to disagree. In advanced protection training, I believe the dog must trust your judgement, both ways. What I mean by that is if something seems wrong to the dog, with his limited understanding, ( we are suppose to be the smarter member of the team) and I tell the dog no, stand down. He must trust my judgement and stay ready but under control. By the same token If the man looks non-threatening to the dog, but I say you must attack, then he again must trust my judgement and attack. The decoy did nothing to appear as a threat to the dog. he walked up, as someone might on the street to greet me. We shook hands as two people might. Now the fact that he had a bite suit on was a que to the dog but with no sign of aggression from the man and no attack command from me, the dog should continue to heel, sit and down just like I asked him to.
If a dog is unsafe in public, being too quick to make his own decisions, then the liability might outweigh just out weigh him as an asset. Then if you noticed, When I sent him, the decoy was not acting aggressive. Again the dog had to take my word for it. Although I must admit this was not
true proof of this because the bite suit was a que.
