Dogs can find errors in simple calculations

Dogs are considered to be the best friends of humans and they are smarter than we often think.

American animal psychologist and dog expert Stanley Coren said: 'People have statistics, an average dog can understand 165 words, count up to 5 and find errors. in simple arithmetic operations. Intellectually, they are equivalent to a baby from 2 years to 2.5 years old. '

The group of researchers from the Hungarian Institute of Scientific Research led by Josepf Topal demonstrated that both dogs and children understand and respond to nonverbal languages ​​such as the eyes and gestures of the owner.

Like children, dogs accumulate knowledge by observing and imitating human actions. Imitation but selective, means that they only imitate and repeat the necessary actions for them.

Scientists at the University of Vienna also found that dogs have a sense of fairness. The two dogs were trained in one movement and were rewarded with the same candy. But many times, get different rewards, the less you feel 'offended' , don't listen to the command anymore.

There are also cases where dogs appear to be inferior to monkeys. When the German scientists of Max Planck Vienna experimented with training monkeys and dogs simultaneously. Food is rewarded for dogs and monkeys in two separate boxes. After that, they swapped the two boxes.

While the monkey knew immediately which box contained his food, the dog did not know that his box was swapped. Experts conclude: Their ability lies in the field of social knowledge.
