Why do puppies do arithmetic?

We know that some puppies are trained to do arithmetic problems. Can dogs really calculate? Let Austrian biologist and Nobel Prize winner Konrad Lorenz tell us the answer:

At first glance, their performance was really shocking. You are invited to set your own exam, and you are arranged opposite a horse, a terrier or other animals. You ask, what is two times two? The beagle looked at you intently and called four times. For a horse, this feat seems even more amazing because it doesn't even look at you. For dogs who closely observe the examiner, it is obvious that their attention is focused on the examiner, not the problem itself. But the horse doesn't need to turn his eyes to the inspector, because it can see the slightest movement through indirect vision even when the animal is not in the direct focus direction. It is you who involuntarily betrayed the "thinking" animal and the correct solution. If one doesn't know the correct answer, the poor animal will knock or bark desperately, waiting in vain for the signal to stop it. Generally speaking, this sign is about to appear, because few people have the ability to keep an unconscious and unconscious signal, even with the greatest self-control.

It turns out that dogs or horses are much more sensitive than humans in some ways. By observing the testers, we can perceive the information they unconsciously reveal-the answer to the question. When you ask a dog an arithmetic problem, it will stare at you and pay attention to your expression and movements, not the problem itself. A horse is more sensitive: it doesn't even have to stare at you directly, and it can detect the slightest movement with a glance out of the corner of its eye. For the vast majority of people, no matter how strong their self-control, they will always unconsciously reveal some information and reveal the answers to questions.
