how long do labradors sleep
Dogs naturally sleep for far longer periods of time each day, than people do. Many adult Labradors will sleep for well over half of every 24 hours, and puppies under four months old may sleep as much as 20 hours a day.ogs on the other hand though less dependent on their eyes, have better night vision than we do. So their ancestors could hunt both by day and by night, if necessary. Sleeping all night had no advantage to your dog, and dogs have not evolved a natural tendency to sleep for a single long stretch of time like we do.
