Why Do Dogs Sleep So Much?

 Ever feel like your dog naps more than your phone charges?

If you’ve ever looked over at your pup snoring for the fifth time that day and thought, “Seriously? Again?” — you’re definitely not alone. I mean, how is it fair that they get to snooze like a professional napper while we hustle through life, fueled by caffeine and sheer willpower?

So… why do dogs sleep so much? Is it just because they can? Or is there some deep biological reason behind all that shut-eye? Let’s dig into it — paws first. 🐾



Dogs Are Basically Professional Sleepers

How Much Sleep Is Normal?

Let’s start with the basics:
Most adult dogs sleep between 12–14 hours a day.
Yep, you read that right. Puppies and senior dogs? They go even harder, clocking in up to 18–20 hours.

That’s not laziness. That’s just... dog life.

To break it down:

  • Adult dogs (1–7 years): 12–14 hours per day
  • Puppies: 18–20 hours (because being cute is exhausting)
  • Seniors: 14–20 hours (old bones need rest)
  • Working breeds (with jobs): Slightly less, but still love their naps

FYI: If your dog sleeps all day and night and isn’t a puppy or senior, don’t panic just yet. Keep reading. :)


Their Sleep Cycles Are Totally Different From Ours

Why It’s Not the Same As Human Sleep

Here’s a fun fact: dogs don’t sleep deeply like we do.
Their sleep cycle is shorter, lighter, and way more fragmented.

Basically, they enter REM sleep (the deep, dream-filled stage) way less frequently than humans. So to get the same amount of quality rest we do in 8 hours, they need more total sleep.

Think of them as “power nappers” with a full-time sleep schedule. Must be nice, right?


Dogs Burn Energy Differently

It’s Not About Laziness — It’s About Efficiency

Ever seen your dog go from zero to zoomies in 2 seconds, then crash on the couch like they just ran a marathon?

That’s because dogs use energy in bursts.
They sprint, play, bark at ghosts (or leaves), and then immediately crash to recharge. Unlike humans, who tend to pace our energy throughout the day (mostly because we have to).

In short:
Dogs are hardwired to go hard and then go nap.
Honestly? Kinda jealous.


Breed Matters More Than You Think

Some Breeds Are Born to Nap

Let’s be real — not all dogs are created equal in the energy department.

Some breeds were bred for high-energy work, like herding sheep or pulling sleds. Others? Their ancestors probably chilled in palaces and lived for belly rubs.

Here’s a quick comparison:

High-Energy Breeds (Need More Mental Stimulation):

  • Border Collies
  • Huskies
  • Belgian Malinois
  • German Shepherds

Low-Energy Breeds (Certified Nap Experts):

  • Bulldogs
  • Basset Hounds
  • Great Danes
  • Shih Tzus
  • Chow Chows (the kings of chill)

If you’ve got a bulldog who sleeps all day? Totally normal.
If your Border Collie’s napping 18 hours a day? Might be time for a vet check.


Puppies Sleep a TON (Like, Seriously)

Because Growing Is Hard Work

Raising a puppy is kind of like raising a baby… except the baby has teeth and eats your shoes.

And just like babies, puppies need more sleep because their brains, bodies, and immune systems are growing like crazy. If your 8-week-old furball is passed out more than he’s awake? Good! Let him.

IMO, nothing is cuter than a puppy in a full-on twitchy dream nap. 😍


They Get Bored — And Sleep Out of It

Yep, Dogs Can Nap From Sheer Boredom

If your dog’s home alone a lot, or doesn’t get enough stimulation, they may just choose sleep as the most entertaining activity available.

Can you blame them? If my only options were:

  • Chew the same bone I’ve had since forever
  • Watch the humans stare at rectangles
  • Or nap?

Yeah. I’d pick napping too. Every time.

Here’s how to fight boredom snoozing:

  • Daily walks (even short ones)
  • Puzzle toys and treat dispensers
  • Training sessions (mental work = tired pup)
  • Doggy playdates (AKA controlled chaos)

Age Hits Hard (Even for Dogs)

Older Dogs Just Need More Zzz’s

As dogs age, they slow down. Arthritis, vision issues, hearing loss — all of it adds up and makes them less eager to move and more likely to rest.

But not all increased sleep is normal. Keep an eye out if your senior dog is:

  • Lethargic even after rest
  • Eating less
  • Losing interest in things they used to love

These could be signs of underlying health issues like hypothyroidism, arthritis, or even cognitive dysfunction (doggy dementia is real, y’all).


Weather Can Affect Their Nap Game

Hot Days = Lazy Days

Ever feel like doing absolutely nothing when it’s blazing outside? Same goes for your dog.

Heat zaps their energy.
They’ll sleep more to conserve it, especially in breeds with thick coats like Huskies, Malamutes, or Saint Bernards (who, IMO, were clearly designed for snow, not sun).

On rainy days, some dogs also get sluggish. Why? Who knows. Maybe the gloom gives them the existential dread vibes too. :/


Health Issues Could Be the Culprit (So Don’t Ignore Changes)

When You Should Worry

While most sleepiness is 100% normal, sudden changes in sleep habits could mean something’s up.

Red flags to watch for:

  • Sleeping way more than usual out of nowhere
  • Acting sluggish or “out of it” during waking hours
  • Sudden weight gain or loss
  • Snoring or labored breathing (especially in flat-faced breeds)
  • Refusing food or water

If you notice any of the above, call your vet. Trust me — you’d rather be safe than sorry.


Quick Tips to Keep a Healthy Dog Sleep Schedule

Want to make sure your dog’s sleeping habits stay in check? Try these:

  • Keep a routine. Dogs love schedules.
  • Give enough exercise. Mental + physical.
  • Don’t wake them up just to cuddle. (I know it’s hard. Fight the urge.)
  • Watch their diet. Good nutrition = better sleep.
  • Visit the vet regularly. Especially if anything seems off.

And yes, I do let my dog sleep in my bed. Judge me. 😅


Final Thoughts: Let Sleeping Dogs Lie (Seriously)

So… why do dogs sleep so much?
Because it’s natural, healthy, and honestly, kind of their superpower.

Whether they’re pups recharging from zoomies, seniors easing into retirement, or just a bulldog being his snorey self — sleep is a massive part of their well-being.

Unless something seems really off, don’t sweat it. Let them snooze. They’re not lazy — they’re just living the dream. Literally.

Now if only I could get away with napping 14 hours a day without judgment. 😴
