Why do dogs sleep so well?
A dog’s life is to eat, sleep, and make peas.
From birth to just weaning, puppies basically sleep apart from eating, drinking, and peeing, and sleeping takes up most of their time.
Generally speaking, young dogs sleep for about 19-20 hours, and some can even sleep for 22 hours;
Adult sleep time is about 10-18 hours, so they sleep for about 10-18 hours a day. Most of the time is spent in sleep.
What are deep and light sleep?
The dog’s sleep is divided into two stages: light sleep and deep sleep.
It seems that those who may fall asleep at any time are light sleep. During light sleep, the dog is prone In a posture, the head is bent between the two front paws, often with one ear close to the ground.
Dogs are easily awakened during light sleep, which is actually a state of vigilance.
But after falling asleep, the defense will be disarmed, the body will relax, accompanied by the twitching of the limbs and the shaking of the head and ears, and some will turn their belly or even emit humming sound.
Generally, it is not easy to be awakened by acquaintances after deep sleep, but it is still very sensitive to unfamiliar sounds. If awakened at this time, they will vent their dissatisfaction.
UK physiotherapist Julia Robertson says it’s extremely important for dogs to have the opportunity to create a comfortable environment for themselves and choose the position they need while sleeping, so when they’re tired they can Give it a good place to sleep.
Dog Sleeping Secrets
Sleep Quadruple

When high-level mammals, including dogs, sleep, they can not only rest their bodies, but also their brains.
And deep sleep that allows the brain to rest is “non-paradoxical sleep”, the same as “paradoxical sleep” that allows the body to rest.
“Paradoxical sleep” refers to a state of semi-sleep with some consciousness, which is manifested as high-frequency brain waves, which affects the secretion of growth hormone during sleep to a certain extent.
When the dog has a sense of safety in the surrounding environment, this safety command signal will be sent to the brain, allowing the dog to gradually enter a deep sleep that is “non-paradoxical sleep”, and then make the brain get Get plenty of rest.
The sleep frequency of dogs is 45 minutes, which is close to half that of humans. The dog’s body and brain will be in “paradoxical sleep”, “non-paradoxical sleep” ” and “awake” states.
According to scientific research, it can be roughly divided into four stages:
① During sleep, the frequency of brain waves slows down;
② During light sleep, brain waves appear It is irregular;
③In deep sleep, the brain wave changes greatly, the frequency becomes smaller, and the amplitude becomes larger;
④Deep sleep. Generally, the time in the state of non-deep sleep accounts for 80% of the total sleep time.
Interpretation of “deceitful corpse phenomenon”:
Intuition of stress response reflection. When dogs are in a light sleep, they may be awakened by any disturbance, and out of vigilance, they will immediately confirm the safety of the surrounding environment;
When in a deep sleep, it is not easy for the owner and familiar people to wake up, but instead. Strangers or loud noises are more likely to wake them up.
Stress response
Stress response is the biggest enemy of deep sleep, it can directly hinder the body and brain fatigue.
Illnesses such as colds, heart disease, stomach ulcers and diabetes often cause stress in dogs.
If this condition persists for too long, dogs with poor sleep can develop a variety of unknown behavioral problems, such as violent restlessness, fights with other dogs, and disobedience.
Note:
Never play tricks on sleeping dogs because of mischief, serious consequences!
Dangers of Insomnia
A dog’s resistance will decrease if it is sleep deprived for a long time. Not only will it cause colds and illnesses, but it is also difficult to treat.
Even though they are usually docile like a little sheep, they will suddenly become very non-irritable, and they will bark constantly and even bite the person who wakes them to sleep.
Sleep plays a vital role in animals.
But what is this effect? Does sleep really allow the brain to repair damage and process information? Is sleep necessary for the regulation of the body?
However, in the long-term sleep research on most animals, a pattern can be found, no animal is completely sleep-free.
In other words: a minimum amount of sleep is also essential.
