How much time dog sleep a day?

You will find your dog is always sleeping every day, when you sleep at night it sleeps, but it is always sleeping during the day. This is because the dog sleep to more than ten hours a day, some fifteen or sixteen hours. Because a dog in the shallow sleep state most of the time, very alert, only a small amount of time can go into deep sleep, so it is always sleeping.
