The study of relationships between different species of animals is still a hot topic for scientists.
Dolphins communicate using whistles, monkeys react to touch, and the fish know how to grunt! And recently, researchers from Italy have established the role of the tail in communication between the dog and its congeners. To determine the mood of a dog is easy enough. To do this, look at her tail. If the animal wags in the right direction for him, it is in a good mood and demonstrates it to you.
If the pet wags its tail to the left, it is worried, upset and tense. As is known, the left and right hemispheres of the human brain react differently to the same signals. An interesting fact is that the left hemisphere has control over the movements of the right side of the body, and vice versa. The dogs are all the same. Scientists conducted special experiments to determine whether dogs respond to how their relatives wag their tails.
For this, animals were shown films that showed real dogs or their silhouettes. It was established experimentally that the pulse of the dogs increased, and they began to whine. And seeing the tail wagging to the right, they calmed down.
However, Italian neurology professor Giorgio Valortigara from the University of Trento comments: “From the first days of life, a puppy notices a pattern: if his brother is upset or aggressive, he wags his tail to the left. When the dog communicates with the embittered relative, he turns his head to the left. While communicating with calm individuals, it leans slightly to the right.
These were the findings of a group of specialists from the University of Lincoln last year. It would seem that everything is clear with the hosts, but John Bradshaw, a dog expert from the University of Bristol, questions the results of the Italians' research. Recently, an experiment was conducted at the University of Victoria in Canada. They put a robot in front of the dog, which for a long time wagged an electronic tail in the right direction.
John Bradshaw claims that the dogs did not experience any negative emotions and calmly approached the robot. He adds that perhaps the whole point is that robots and silhouettes in films cannot completely recreate the image of a living dog. And because the dog's reaction to the present animal may be different.
