New puppy basics
How much should an 8 week old puppy sleep?
Last updated 23 September 2026 · How we write and check this
Short answer
An 8 week old puppy typically sleeps 18 to 20 hours a day, spread across many short naps rather than one long block. This is normal even if it looks like a lot, since growing brain and body tissue does most of its repair work during sleep at this age.
Naps come in short, frequent bursts
Do not expect a single long nap. An 8 week old puppy might play hard for 15 to 20 minutes, then crash for an hour or two, several times across the day. That pattern is normal and tends to lengthen into fewer, longer naps by four to five months.
Overtired puppies get worse, not calmer
A puppy that is kept awake and stimulated past its limit often becomes more hyper, mouthier and harder to settle, not sleepier. Scheduling quiet nap time every hour or two of activity, even if the puppy resists at first, usually improves behavior noticeably.
Key takeaways
- 18 to 20 hours of sleep a day is typical for an 8 week old puppy.
- Sleep comes in many short naps rather than one long stretch at this age.
- An overtired puppy tends to become more hyper and bitey, not calmer, so scheduled nap breaks help.
