how long puppies need to sleep
By 16 weeks, most puppies should begin sleeping through the night, though there may still be occasional nights your puppy needs to get up and go outside. On average, you can expect your puppy to sleep six to 10 hours at night. Puppies spend 16 to 20 hours sleeping every day depending upon their age. This means that, in addition to her 6 to 10 hours of nightly sleep, you can expect your puppy to spend as much time during the day asleep as she spends awake.
