“And you, Brutus?”
Scientists from Switzerland conducted an experiment which involved 27 dogs. Before animals were three boxes: one was sausage, the second biscuits for dogs, and the third left empty. The dogs had to take turns to bring two people to the boxes. The first participant of the experiment gave the dog what was in the box, and the second was left to himself.
In the experiment, the dog noticed that not always they get a treat. Then, if they caught the person who shared the food they had brought him a box of sausage, and if the one that left everything to empty.
Thus, scientists have noticed that dogs can manipulate people for their own benefit.
