Dogs are all honest, loyal and obedient, right? Well, not always. Our pets can be sneaky and manipulative when they want to maximise the number of tasty treats they get to eat.Marianne Heberlein, who studies dog cognition at the University of Zurich in Switzerland, wanted to test the animals’ ability to use deception to get what they want from humans.She got the idea to study doggie deception from watching her own dogs. One occasionally pretends to see something interesting in the backyard to trick the other into giving up the prime sleeping spot. “This sort of thing happens quite often, but it is not well studied,” she says.To see if dogs would deceive humans too, Heberlein and her colleagues paired various pooches with two partners – one who always gave the dog treats and another who always kept the treats.
