You just brought home this tiny, vibrating ball of fur and energy. One minute they’re Shredder from the Ninja Turtles, tearing through your expensive wool rug and terrorizing your socks, and the next? Gone. Out cold. Head in the water bowl, snoring like a freight train. It’s a bit of a shock to the system. You’re probably sitting there wondering if something is wrong, or if you just got a particularly lazy model.
Honestly, it’s normal.
When you ask how long do puppies sleep, the answer usually lands somewhere between "a lot" and "is this creature actually alive?" We are talking 18 to 20 hours a day for the youngest ones. It’s a marathon of napping. Think about it this way: a puppy’s brain and body are doing more heavy lifting in six months than you’ll do in a decade. They aren’t just resting; they’re building a nervous system from scratch.
Why your puppy is basically a professional sleeper
Puppies are the ultimate "work hard, play hard" enthusiasts. Their bursts of energy are intense because their bodies are flooded with growth hormones that only really do their best work during deep sleep. According to the American Kennel Club, sleep is vital for the development of their central nervous system, immune system, and muscles.
It’s intense.
If they don't get that massive chunk of shut-eye, you end up with a "land shark." You know the one. That overtired puppy who loses all impulse control and starts biting everything because they literally cannot regulate their own emotions anymore. It’s exactly like a toddler having a meltdown at Disneyland because they missed their nap.
The age factor: It changes fast
A 8-week-old puppy is a different beast than a 6-month-old.
Newborns? They’re basically 90% sleep. They twitch, they whimper, and they grow. By the time they hit the 8-to-12-week mark—which is when most people bring them home—they are still clocking in 18 to 20 hours. You’ll see them play for 30 minutes and then crash for two hours. That’s the rhythm.

As they creep toward the six-month mark, you might see that total drop to 16 or 18 hours. They stay awake longer. They have more stamina. But even an adolescent dog needs way more sleep than you do. If you’re getting 7 hours and feeling okay, your dog is looking at you like you’re a superhero. They need the downtime to process everything they learned during their training sessions.
The "Puppy Zoomies" vs. The Crash
Ever heard of the Witching Hour? It usually happens around 7:00 PM.
The puppy starts sprinting in circles. Their eyes get wide. They growl at their own tail. This is often a sign that they are actually overtired. It sounds counterintuitive, but a puppy that won’t stop moving is usually a puppy that desperately needs you to put them in their crate or a quiet space so they can finally "turn off."
Dr. Mary Burch, a certified applied animal behaviorist, often points out that puppies don't always have an "off switch" that they know how to use. They’ll keep going until they drop. You have to be the parent who enforces the nap.
Creating the "Zen Zone" for sleep
You can’t just expect a puppy to sleep in the middle of a chaotic kitchen while you’re making dinner and the kids are screaming. Some will, sure. But most need a dedicated spot.
- Crate Training: It’s not a jail. It’s a den. Put a cover over it to make it dark.
- White Noise: Sometimes a fan or a white noise machine helps drown out the sound of life so they don't wake up every time a floorboard creaks.
- Temperature: Puppies can get hot. If they’re panting in their sleep, they might need a cooler spot or a different bed.
Real talk: What if they sleep too much?
There is a line. While how long do puppies sleep is a question that usually leads to high numbers, you should know what’s weird.
If your puppy is awake but seems lethargic—meaning they don't want to play, they aren't interested in food, or they seem "out of it"—that’s a red flag. Healthy puppy sleep is deep, but when they are awake, they should be bright-eyed and curious. If they’re sleeping 20 hours but the 4 hours they are awake are spent moping, call the vet. It could be anything from parvo (hopefully not) to a simple stomach upset or anemia from parasites.

Also, watch the breathing. Puppy dreams are wild. They kick, they "yip," and their breathing gets irregular. That’s normal REM sleep. But if they are struggling to breathe or coughing while resting, that’s a different story.
The Nighttime Struggle
Let’s be real for a second. Even though they sleep 20 hours a day, they rarely do it all at once when you want them to.
Their bladders are tiny. A general rule of thumb is that a puppy can hold it for one hour for every month of age. So a two-month-old? Two hours. Maybe three if you’re lucky. This means those 20 hours of sleep are broken up into a million little chunks. You are going to be tired. It’s part of the tax you pay for the cuteness.
Setting a schedule that actually works
Dogs crave routine. If you want to maximize their sleep (and yours), you need a rhythm.
Wake up, immediate potty trip.
Breakfast.
Play/Training (15-30 mins).
Nap (1-2 hours).
Repeat.
If you follow this "one hour out, two hours in" rule, your life will get significantly easier. It prevents the overtired biting and helps with housebreaking because you always know exactly when they last went out.
Honestly, the biggest mistake new owners make is thinking the puppy needs to be entertained every second they are awake. They don't. They need to learn how to be bored. Learning to settle is a skill. If you constantly throw toys at them, you’re just building an athlete that will eventually need four hours of exercise a day to stay sane. Teach them that napping is a job.

Why do they twitch so much?
It's actually kinda cute, right? The little "paddling" paws.
Research suggests dogs dream just like we do. They go through stages of wakefulness, Rapid Eye Movement (REM) sleep, and non-REM sleep. During REM, their brains are processing the day's events. Maybe they're chasing that squirrel again or finally catching that elusive tennis ball.
Don't wake them up.
There's an old saying: "Let sleeping dogs lie." It’s true for puppies especially. If you startle them out of a deep REM cycle, they can wake up disoriented and might nip or get scared. Plus, you're interrupting that crucial growth hormone release.
Actionable steps for a well-rested puppy
- Track the hours: For the first few days, actually jot down when they sleep. You’ll likely see it’s around 18-20 hours. If it's less than 15, you probably have a cranky puppy on your hands.
- Enforce the nap: If the puppy has been awake for an hour and is starting to act like a jerk, put them in their quiet space. Don't wait for them to pass out on the floor.
- Check the environment: Make sure the sleeping area is safe. No loose wires to chew on if they wake up bored. No small toys they could swallow.
- The "Last Out" ritual: Take them for a boring, no-nonsense potty break right before you go to bed. No playing, no talking. Just business.
- Watch the diet: High-quality food matters. Cheap fillers can lead to energy spikes and crashes, or even tummy aches that keep them awake.
Understanding the rhythm of puppy sleep is basically the "cheat code" to surviving the first few months of dog ownership. They aren't just lazy; they are under construction. Let them sleep, give them a routine, and soon enough, you’ll have an adult dog who knows how to chill.
Next Steps for Success
Check your puppy's gums. They should be a healthy bubblegum pink. If they are pale and your puppy is sleeping more than usual, it’s time for a vet visit to rule out any underlying issues. Otherwise, embrace the silence while it lasts, because once they wake up, the chaos begins again. Look into "Calm Settling" protocols like the one developed by Dr. Karen Overall if your puppy struggles to switch off; it's a game-changer for high-energy breeds. Be patient with the process. Your rug will eventually be safe again. Probably.
