The command was repeated as often as required – until the dog stopped trying to eat the food. Then the experimenter slowly walked backward and sat on the ground at the predetermined location. The trial ended after 60 seconds had elapsed without the dog taking the food. After the 60 seconds had elapsed, the dog was encouraged to take the food with the words ‘Geh ab!’ or ‘Jetzt nimm’s!’ (German for ‘You can take it now!’).”
They lost me right there because my dog, Wag, would just stare interestedly at my pointing finger, get bored and start licking himself inappropriately and then look up in astonishment when I'd say “Aus! Nein! No! Eeeeew!” in a low, firm, grossed-out tone.
Back to the study and dogs that are actually trained and bilingual, because assuming the dogs speak human and German Human was just given. They also, hilariously, assumed that, “It is unlikely that the dogs simply forgot that the human was in the room when she was not illuminated.”
I could not compose myself after reading that line because my collie-poodle “cadoodle” dog greets me like I've just walked in the front door when I leave the room to get a cup of coffee and return. “Hey! You're here! I can't get over it,” is what he seems to say as he recovers from the shock.
So while dogs may indeed be more prone to dark deeds when the lights are off, the next time anybody does a study about food being swiped in the dark where a dog is taking the fall for the crime, I think they should first check the building for cat burglars.
