We trust our dogs, don’t we? Our loyal companions. Man’s best friend? Well, if a 2017 study in animal behavior is to be believed, our butter-wouldn’t-melt-expression-wearing buddies are actually capable of “tactical deception” (or “lying,” in layman’s terms!).


On day one, study leaders trained the dogs to distinguish two humans according to how readily they offered food. The “cooperative” human handed out a dog treat with no complications; the “competitive” human presented the treat, but quickly pocketed it.
Unsurprisingly, test day one revealed that the pups preferred the “cooperative” human.
On day two, the dogs were taught how to lead a human to food, following the instruction “Show me the food.” Favorite food and non-preferred food were placed in two identical boxes alongside a third, empty box. The well-trained dogs led their humans, and if they ended up at a box full of food, the “cooperative” partners (very cooperatively indeed) rewarded their dogs with the tasty snack.

“Competitive” partners, on the other hand, kept the food for themselves, although your guess is as good as ours as to whether or not they ate it.
Over half of the savvy participant pups realized that leading their “competitive” human to the box of preferred food would likely result in an empty stomach and a whirlwind of disappointment. So what did they do? They lied.

“These results,” the study authors shared, “show that dogs distinguished between the cooperative and the competitive partner, and indicate the flexibility of dogs to adjust their behavior.” Put down your coffee mug, stare your sweet pooch directly in the eyes, and absorb the ghastly reality: dogs, the study concluded, are “tactical deceivers.”
“Be careful and precise in rewarding your dog,” she advised.

“That’s one of the reasons they are so trainable.”
With that sympathetic synopsis, it’s easy to have great respect for our industrious companions. They’re smart. Perhaps smarter than we ever thought. And they’re excellent at getting what they want!
