That's a very weird video. The editing is awful, and the strangest thing about it is that the sound isn't a real dog. I know this because for the past 8 months I can't watch a single thing with dog sounds in it without having my puppy bark. I played it 4 times in the past few days, and every time, not a peep out of him.
So then I got curious, and I googled Patrick Keil IPO, in discussions listing, and opened a few of the German pages, with the pages translated for me. Most of the talk is going on about how inhumane it is, but one person said that he got kicked out not because of the way he trains, but because of something else - some arguement? I had a hard time understanding because the computer is a poor translator, but something seems fishy to me. I think there's a good story behind this video, but we'll probably never get to hear it.
