How much sleep does a dog need?

The average amount of sleep for adult dogs is 12–14 hours per day.

Charlie loves to sleep. He can sleep anywhere but usually sleeps in the room I'm in. So now while I write this he is in the office/bedroom on the floor. When I leave the room he will follow me. 

Dogs sleep in short and long stretches throughout the day and night. Dogs almost spend half their life sleeping. It is important to teach children and guests to not approach your dog while its sleeping. A dog that is startled can jump or bite.
