A dog is an omnivorous mammal from the canine family, domesticated more than 10 thousand years ago. Dogs are able to understand 250 words and gestures, count to five, and also perform simple mathematical operations.

A dog is man's best friend, always there, always gives a paw and wags its tail). It is worth mentioning that the smartest dog breed is the poodle.

The intelligence of dogs is a scientifically proven fact. These animals are trained, they have a good memory. Recent studies confirm that the dog is a very intelligent friend of man. Scientists at Harvard University, USA, working under the guidance of Professor Mark Hauser, proved that dogs are able to "parody" human facial expressions and gestures. They are echoed by scientists at the Vienna University of Psychology, who published the results of research in the journal Current Biology, convinced of the ability of these animals to "selective imitation."
