First video, [u]laughable[/u]. If they really expected that there pooches would do anything more than what we saw, then the owners must be delusional. Second video, [u]apples to oranges[/u]. Part 1: Three MALE(!) dogs, all it appears from solid West-German lines (Elvis is a beautiful GSD btw). The decoy has a face mask on and acts way suspicious. He also has a protective arm sleeve as prey stimulus for the dogs. Part 2: Three FEMALE(!) dogs, they don't appear to be from decent lines (maybe AKC?). The decoy has a hat and most of his aggression is initially expressed in his language. Let alone that the girl probably hasn't bonded with any of the females and that the males weren't protecting her but actually acting on trained prey drive. The males could have cared less about the well being of the girl as this was NOT a defense driven response. (I shouldn't even mention that I wasn't that impressed by their bite either) Lastly, they all ARE GSDs afterall, so what do you really expect? They are born to be trained for working tasks like this. Therefore you'll see that untrained dogs don't perform whereas trained dogs do, duh. Let's face it, it's an ad for a dog training facility. Nice try though. When I recall the numerous encounters of my Shars with people who are acting suspicious, I know that training is not necessary here. When it's anchored in the hardware, I don't have to worry about the software. Dan
