We know that the normal sleep time of a person is generally around 7-8 hours, while cats can sleep for more than ten hours. How long can a dog sleep in a day? Is it longer or shorter than the cat?

Under normal circumstances, the dog's sleep time per day is about 15 hours, but this is the sleep time of adult dogs. For puppies who are several months old, they will sleep up to 22 hours. Adequate sleep can relax the dog's spirit and help the dog recover its physical strength. So, when dogs sleep, do not disturb them.

Dogs do not sleep all night like us. Even if the dog is used to the owner's life rules and will sleep with the owner at night, they will still be vigilant. Their ears are still working. Although their eyes are closed, if there is a slight noise, the dog will quickly open his eyes to observe the surroundings. This is to discover any changes around it as soon as possible, so you will find that when the dog is sleeping, his head always heads towards the door.

Dogs always stay alert when sleeping? In fact, it is not. Only when the dog is sleeping lightly can it make a little noise and open its eyes immediately. Once a dog enters a deep sleep period, its response will not be so sensitive.

Dogs entering deep sleep will not wake up from slight noises, and their bodies will relax. Their sleeping positions are surprisingly surprising. Occasionally, they make slight moans because of dreams, and sometimes their limbs will twitch and their limbs are extremely cute.

 Although dogs sleep a lot of time in the day, most of them sleep lightly. If you find that your dog is sleeping and it will not open its eyes when you pass by, and it will be accompanied by a slight cry, then at this time, the dog is entering a deep sleep period. At this time, don’t disturb your dog, because only during the deep sleep period can the dog be considered to be really resting.

If a dog does not sleep deeply for a long time, it will be depressed due to lack of sleep, which may even lead to a decrease in the dog's immunity and easily get sick.
