Someone in France thought it would be interesting to see if a German Shephard would tell the difference between a Sony AIBO and another dog. Trouble was, they thought it would be cool to test while offering the Shephard a fine cut of meat. I think the result is clearly the same no matter if it's a robotic dog or a full-grown human; don't fcuk with a dog and his food. Apparently even Sony can't find smart French people. Link.
