How long a dog sleeps has a lot to do with her age. Like a newborn dog, it sleeps almost every day and can sleep up to 22 hours a day. But as the dog gets older her activity levels increase and her sleep time decreases. Although her sleep time decreases, the dog's sleep time should be about 15 hours. So you think why does a dog sleep every day, because she does sleep a lot more than a human
Today's pet dogs are getting better sleep because their quality of life is improving. Owners may find that their dogs sleep longer during the day. This time she was in a light sleep, a sound can wake it up. At night, it slept soundly and even made noises and snored in dreams.
