Samoyeds do not have a fixed sleeping time. They can sleep 24 hours a day and sleep when they have the opportunity. Generally speaking, they can sleep an average of 12-15 hours a day. However, the more concentrated sleep time is mostly around noon and two or three o'clock in the morning. The length of sleep varies every day. When dogs sleep, they always like to hide their mouths under their two lower limbs. This is because the dog's nose has the most sensitive sense of smell and must be well protected.
