What is dreaming dog?

"Did the dogs have dreams?" - will ask with surprise those who have never kept the dogs. "Of course!" - exclaim those who have the good fortune to live with a tailed friend. Every dog owner probably noticed that the dog rarely sleeps calmly, quite often in a dream you can notice a twitching of the paws, a stirring of the eyes under the covered eyelids, and sometimes even a little whine. All this is evidence that the dog has a dream, and in this article we will tell what your pet can dream.

Opinion of scientists

It is interesting, but some time ago the best minds of mankind were sure that animals do not dream. Scientists believed that since animals, unlike humans, do not have a second signaling system, then the pleasure of dreaming is not available to them. However, when the researchers seriously addressed the study of the mechanism of sleep, they changed their minds to the opposite, saying that the animals are definitely not deprived of the opportunity to see dreams.

Fast (paradoxical) and slow sleep

Studies have shown that there are two phases of sleep - slow and fast.

During the slow phase of sleep, muscle tone is lowered, the sleeper breathing regularly and regularly, the eyeball still. Slow sleep, as you already guessed, is also characterized by a lack of dreams and serves only to restore the physical and moral strength of the sleeper.

When a person or an animal goes into REM sleep, the cardiac activityDogthe vascular and respiratory systems become more active, and the eyeball under the eyelids begins to move. A dreaming sleeper sees precisely during the REM sleep phase.

The difference between the dreams of man and animal is, perhaps, only in the duration of the fast phase. However, the fast sleep phases of humans and dogs differ little. Rapid sleep of an adult person takes 23% of the total sleep time, dogs - 25%. It is interesting that puppies can be in the fast phase up to 90% of the sleep time, but the quick sleep of rabbits takes only 3%. By the way, today scientists are confident that dreams are not only mammals, but also birds.

Methods of studying the dreams of animals

Large-scale studies of the dreams of animals were conducted in the 80s of the last century.The group of scientists under the leadership of doctor Adrian Morrison was engaged in it. It is worth noting that if you consider yourself to be active zoodefenders, the method of research by Morrison will cause outrage in you, but you should understand that the opportunity to look into dreams is difficult to access, especially when talking about animals.

Before outlining the essence of the methodology, it is necessary to make an important explanation. ATDogthe brain has a special area called the blue spot area. This very zone is responsible for ensuring that the sleeper does not actually perform the actions that he dreams of. In the event that this area is destroyed, the sleeper begins to perform the actions taken by him in reality, but he does not wake up. Actually, the essence of the technique was the destruction of this area, and then the observation of a sleeping animal.

The first subject was a cat. She had an operation to destroy the "blue spot" and first watched her in the waking state. The cat behaved quite naturally - she saw, ate, played and purred. In general, all actions are consistent with the actions of a normal cat. During the slow phase of sleep, the cat also behaved quite naturally, snoring peacefully, but when the fast phase began, the object of research turned into a "lunatic."The cat was fast asleep, but at the same time she ran around the laboratory, caught an invisible mouse and purred, catching the prey.

And what do dogs dream?

Of course, scientists could not confine themselves to the study of cats only, and therefore at some point it came to dogs, moreover, variousDogbreed, in order to find out whether the life experience of an animal affects dreams, and it turned out that it affects. So, for example, dogs that hunt along with the owner in a dream constantly run around, catch someone, call the owner for invisible prey, etc. But the guard dogs, on the contrary, are in place, only occasionally shifting from one foot to the other and loudly barking at the invisible enemy. In general, as you can see, everything is the same as in people - what I saw in my life, I saw it in a dream.

By the way, scientists have discovered an interesting fact, but so far they have not explained it - small dogs dream of dreams more often than their big relatives.
