A new puppy seems to run on two settings: full speed and fast asleep. When the full-speed setting arrives in the evening as sharp little teeth and wild zoomies, it is easy to read it as naughtiness. Often it is simply a tired puppy who missed a nap, a bit like an overtired toddler.
Puppies are growing fast, so they sleep a lot. Sources do not agree on one number. The animal charity PDSA says some puppies sleep 18–20 hours a day, VCA Animal Hospitals gives a wider 10–14 hours as normal, and a veterinary review in the AAHA journal notes that popular figures of 18–20 hours are higher than the roughly 11 hours measured in one study of puppies. So treat any single figure as a guide, not a target. What matters more is that your puppy gets regular, undisturbed rests and wakes up rested.
Sleep also comes in pieces. Puppies do not sleep in one long block; they nap many times across the day and night, so a daytime nap is normal even after a full night.
Many trainers suggest short awake stretches for young puppies: around 45 minutes to an hour at 8 weeks, slowly growing to two hours or so by five or six months. This is a rule of thumb, not an official standard, and every puppy differs. Use the planner below to see what a day could look like, then adjust to your own puppy.
8 to 26 weeks. Always follow your vet's advice about when your puppy can go out and meet the world.
Pick one to see what it might mean.
Naps are not a treat. For a young puppy they are part of the day, like meals.
Pick a quiet, safe spot where your puppy will not be disturbed, such as a crate or a pen with a bed in it, and ask everyone in the home to leave them alone while they are in it. PDSA suggests several "snooze spots" around the home. A rectangular bed lets a puppy stretch out, and many puppies choose to sleep close to people, so a bed in the same room works well at first.
The first nights can be hard, because your puppy has just left their mother and littermates. PDSA advises deciding where they will sleep from the start, keeping the bedtime routine calm, and staying nearby for the first few nights. Crying is normal while they adjust, and comforting a frightened puppy is fine: it will not spoil them. Small bladders also mean a night-time toilet break may be needed for the first few weeks.
Plan the busiest play earlier in the day and move to quiet things like chews and a snuffle mat in the evening. A big burst of exercise right before bed can leave a puppy wound up.
Ask your vet if your puppy seems unusually tired or floppy, if their sleep pattern suddenly changes, if they are restless every night, or if they snore loudly or gasp. Your vet can also tell you when your puppy is safe to go out and meet the world, which depends on their vaccinations.
