How Much Sleep Does a Dog Need? More Than You Think
Free guide · The Whole Dog Approach

How much sleep does
your dog actually need?

The short answer

Adult dogs: 18 to 20 hours a day. Puppies: 20. Way more than the 12 to 14 you'll read elsewhere. More sleep equals less arousal, and most of the "naughty" behaviour I get emailed about comes from a dog running miles short of it. So the real question is why your dog isn't sleeping.

Why do dogs need so much sleep?

Sleep is your dog's reset. Everything exciting or scary in their day pushes arousal up, and sleep is what brings it back down. A dog getting their 18 to 20 hours starts each walk calm, shakes off big days, and can actually think when you ask something of them.

"More sleep equals less arousal. Simple stuff."

A dog running short doesn't look sleepy, though. They look naughty:

Can't settle Ignores you outside Pulls like a train Evening zoomies Reacts to everything "Never seems tired"

I hear about these dogs every day. They get called hyper, stubborn, "a nightmare", sometimes even "separation anxiety". But dogs are results of the lives they're living, and a lot of those lives are running on half the sleep they need. Which brings us to the actual question.

So why isn't your dog sleeping?

You can't make a dog sleep. Sleep happens on its own when the conditions are right. If your dog gets nowhere near 18 to 20 hours, one of three things is usually wrong, and all three are bigger than a "sleep problem".

Reason 1

They're not fulfilled

Every breed was built to do a job. Employ your dog or they'll go self-employed: stealing, digging, shredding, barking at the fence. And a dog with an unfinished job stays on the clock. Dogs on the clock don't sleep.

Reason 2

They're too aroused to switch off

Arousal works like nitro, not fuel. However tired the dog is, if something has spiked them, adrenaline keeps them up, restless and buzzing. A cold shower would do the same to you at 2am. And when arousal goes properly through the roof, that adrenaline can hang around in the blood for up to three days. One mad Saturday can wreck sleep until Tuesday.

Reason 3

The day is shaped wrong

This is the one that catches good owners out. Most dogs' days are full of what I call full stops: play, walk, visitors, dinner, then we expect them to just stop. A dog who's still buzzing when sleepy time arrives won't sleep, even if they're tired and fulfilled. That leftover buzz has to go somewhere, so it becomes the 9pm zoomies, the pillow sucking, the dog humping his bed after dinner. They're trying to bring themselves down, because the day didn't.

The bit people miss

For a dog to sleep, three things have to be true at once: fulfilled, tired, and relatively calm when sleep time comes. Miss one and the sleep doesn't happen. So if your dog isn't sleeping, the sleep is a symptom. Something underneath, their needs, their arousal or the shape of their day, is out of balance. Sort that and sleep turns up on its own. Skip it and no amount of tiring them out will get you there.

Understimulated or over-aroused? Do the test

Give your dog something calming: scattered food to search out, a chew, a lick mat. Then watch what happens.

They settle, and stay settled →
Over-aroused. Something in the day keeps spiking them, and they needed help coming down. Worth asking: what's the cold shower in your dog's day, and why does it keep happening?
They bounce straight back up →
Understimulated. The day isn't meeting their needs, and no calming product fixes a bored dog. Dogs don't suddenly become understimulated, it builds over weeks. Worth asking: what was your dog bred to do, and when did they last get to do it?

Either way, the answer lives in your dog's day. Which is honestly good news. The day is the one thing you can change.

This is one piece of a system

Sleep, needs, arousal and the shape of the day all pull on each other, and fixing one usually means touching the others. Inside MK9Plus I teach you the whole system, step by step, in the right order. It's how you learn to actually live with your dog.

The first sign it's working

Members always ask how long this takes. I never trust timelines, dogs aren't washing machines. But you'll know it's working early, because the first sign is this:

"The first sign things are working: the dog starts sleeping a bit more. That's it."
My own dog

Enzo: six hard days a week, to hardly any

Enzo, my rescue, came to me frustrated and easily aroused. Six really hard days out of seven. As his day got rebuilt, that went to five, then four, then three, down to a couple every two weeks.

Now? A million squirrels could be out on tomorrow's walk and it will hardly touch him, because when we get home, he just sleeps. That's what the right lifestyle looks like.

Fair questions about dog sleep

The ones owners actually ask me, answered straight.

How many hours a day should my dog sleep?
Adult dogs: 18 to 20 hours a day. Puppies: 20. Split across the day and night, not one long block. If your dog gets nowhere near that, and you're also living with hyperactivity, pulling, poor recall or a dog who can't settle, the sleep is where I'd look first.
Will more exercise make my dog sleep?
Usually not, and it can make things worse. Arousal works like nitro, not fuel: a spiked dog stays up, restless and buzzing, no matter how empty the tank is. To sleep, a dog has to be fulfilled, tired and relatively calm, all at once. Exercise only touches one of those three, and done at the wrong time it wrecks the other two.
Why is my dog hyper at night?
The evening collects whatever the day didn't deal with. Either the day hasn't met your dog's needs, so all the unspent energy lands at 9pm, or something exciting happened and nobody wound the dog back down afterwards, so they're trying to do it themselves. The zoomies are the symptom. The day is the cause.
Should I crate my dog to force naps?
No. Sleep is encouraged, never enforced. Shutting a dog away to make rest happen builds a bad association with the very place you want them to relax. And if your dog will only rest when physically shut in, that tells you the problem is the day, not the dog.
Is my dog sleeping too much?
Rarely. A dog sleeping lots with their needs met is a content dog. What matters is change: a sudden increase in sleep, lethargy, or a dog who seems flat and withdrawn is a vet question, not a training one. Check the boring explanations too. One member's Sheltie kept sleeping by the front door. Not a disorder, just the coolest, draftiest spot in the house for a double-coated dog.
How long until my dog starts sleeping more?
I never trust timelines, dogs aren't washing machines. Progress is jagged. But the first sign things are working: the dog starts sleeping a bit more. That's it. That's what you're watching for.
