How to Tell if Your Dog Is Getting Enough Sleep — The Complete Guide
There's a moment every dog owner knows. You've just come back from a long walk, you've fed them, played with them, given them plenty of attention — and instead of settling down, your dog is still pacing, still demanding, still unable to switch off. The instinctive response is to assume they need more exercise, more stimulation, more of something. The counterintuitive truth is they might need the exact opposite. They might simply need to sleep.
Canine sleep deprivation is one of the most under-discussed topics in dog welfare, and one of the most frequently misdiagnosed. The behaviours it produces — restlessness, hyperactivity, irritability, reactivity — look so much like other problems that owners spend months trying to solve the wrong issue. Understanding how much sleep your dog actually needs, and how to spot the signs that they're not getting it, could be the most useful thing you read this week.
How Much Sleep Do Dogs Actually Need?
The first thing that surprises most dog owners is the raw number. Dogs need significantly more sleep than humans — and significantly more than most owners realise they're getting.
Adult dogs spend about 50% of their time sleeping in a 24-hour period, which works out to roughly 12-14 hours every day. Most adult dogs seem to need between eight and 13.5 hours of sleep every day, with an average of just under 11 hours.
But that average masks significant variation based on three key factors: age, breed, and activity level.
Sleep By Age
Puppies need 16-20 hours per day — their rapid growth and learning require long periods of rest. Adult dogs typically need 9-14 hours per day, depending on energy level and lifestyle. Senior dogs need 14-20 hours per day, as older dogs nap more frequently and fatigue easily.
The puppy figure surprises almost every new dog owner. A puppy sleeping 18 hours in a day isn't lazy or unwell — their brain and body are in an intensive developmental phase that requires enormous amounts of restorative sleep to fuel properly. Waking a sleeping puppy to interact with them is one of the most common mistakes new owners make.
Senior dogs at the other end of the scale return to near-puppy sleep requirements for the opposite reason — their bodies need more recovery time, their metabolisms are slower, and their immune systems require more rest to function properly.
Sleep By Breed And Size
High-energy working breeds like Border Collies, Australian Cattle Dogs, and Belgian Malinois generally need less sleep — around 10-12 hours — but require plenty of activity and mental stimulation when awake to stay balanced. Large breeds like Labradors, Golden Retrievers, and German Shepherds often require significant downtime, particularly after vigorous activity.
Large dog breeds sleep more than smaller dogs. They may nap for as much as 18 hours per day. This is thought to be related to the higher energy demands of larger muscles and internal organs, as well as metabolic rate differences between large and small breeds.
Dogs Are Polyphasic Sleepers
One crucial thing to understand about dog sleep is that unlike humans — who consolidate most sleep into one overnight block — dogs are polyphasic sleepers, meaning they don't get all their rest in one big block. Instead, they doze off and on throughout the day.
This is completely normal and reflects their evolutionary heritage as carnivorous predators who could afford to rest in short bursts because they weren't prey animals constantly at risk of being eaten. On average, adult dogs typically take two to four naps each day, with a normal dog nap lasting anywhere between 30 minutes to a couple of hours.
The practical implication for dog owners: multiple naps throughout the day are healthy and normal. A dog that sleeps in bursts of 1-2 hours several times throughout the day is doing exactly what their biology designed them to do.
The Signs Your Dog Is Getting Enough Sleep
A well-rested dog has a distinctive quality that experienced dog owners recognise immediately — a kind of settled, contented ease that runs through everything they do.
They settle quickly and voluntarily. A rested dog will choose to go to their rest space and lie down without being directed. They don't need to be encouraged, bribed, or settled by you — their own nervous system guides them toward rest naturally.
They reach deep sleep reliably. You'll see the physical signs — twitching paws, flickering eyes behind closed lids, slight vocalisations. Dogs begin to dream about 20 minutes after they fall asleep. When that happens, their breathing may become irregular and their eyes move behind the lids. A dog that regularly reaches this deep dreaming sleep is getting genuinely restorative rest.
They wake calm and oriented. A well-rested dog wakes gradually, stretches, and re-engages with their environment calmly. They're not immediately reactive to sounds or movements.
Their behaviour is consistent and predictable. Rested dogs respond to familiar commands reliably, engage positively with people and other dogs, and manage everyday stimulation without overreacting.
They have good energy for activity, then rest properly after. The pattern of a well-rested dog is: engaged and energetic during activity, then genuinely settled and resting during downtime. The two states are clearly distinct.
Signs Your Dog Is NOT Getting Enough Sleep
This is where it gets important — and where many owners have been misreading their dog for months or even years.
1. Hyperactivity And Inability To Settle
This is the most counterintuitive sign and the most commonly misdiagnosed one. Lots of sleep-deprived dogs act more like they've had too much coffee. Instead of being calm, they may act restless — pacing non-stop, barking excessively, or chewing on things that they shouldn't. Counterintuitively, tired dogs often act a lot like under-exercised dogs dealing with pent-up energy.
If you've been increasing your dog's exercise in response to hyperactivity and nothing is improving — consider whether the real issue is sleep deprivation rather than under-exercise.
2. Increased Irritability And Reactivity
Sleep deprivation significantly impacts dogs' emotional regulation and impulse control. Common signs of sleep deprivation include excessive yawning, irritability, and heightened reactivity.
Some sleep-deprived pups may be more irritable, which makes them more prone to behave in a reactive or aggressive way. Other sleep-deprived dogs may act depressed and lose interest in activities they normally enjoy.
A dog that suddenly seems grumpier, less tolerant of handling, more reactive to other dogs or sudden sounds — especially one that was previously calm in those situations — may be running a significant sleep deficit.
3. Clumsiness And Poor Coordination
Having good motor skills requires the brain to be at its best. When they don't get enough sleep, it's common for dogs to be less coordinated than usual. They may be clumsier than at other times and not as fluid in their movements.
A dog that keeps missing catches, trips over obstacles they'd normally navigate easily, or seems physically less coordinated than usual — this is the brain running on insufficient rest.
4. Difficulty Learning Or Following Known Commands
Sleep is vital for your dog's brain. Rest helps dogs consolidate memories and process the events of their day, which is especially important when they're learning new commands, tricks, or behaviours.
It's possible your dog could forget learned commands or where to find a familiar spot in the home if they're not getting enough sleep.
If your dog seems to have forgotten commands they've known for months, or is struggling to retain things you've been training consistently — inadequate sleep could be a significant contributing factor. A tired brain simply cannot consolidate learning effectively.
5. Increased Anxiety And Stress Sensitivity
Too little sleep can compound problems for dogs with anxiety because they need to be well-rested to handle stress effectively. Anything that triggers them will be more likely to lead to a freak-out, whether it's a loud noise, anything unexpected in their routine, or something they dislike.
The analogy to humans here is perfect — everything feels harder and more overwhelming when you're running on insufficient sleep. The same is genuinely true for dogs at a neurobiological level. A dog managing anxiety, reactivity, or fear-based behaviours will always manage them worse when sleep-deprived.
6. Physical Signs — Lethargy, Dull Coat, Increased Appetite
Chronic sleep deprivation in dogs can take a physical toll. Look for signs like droopy eyes, a dull coat, or increased susceptibility to illness. A tired immune system may make your dog more prone to infections or delayed recovery from minor health issues.
It's common for tired pups to have an increased appetite and gain weight. Lack of sleep can have negative effects on health because it is associated with a weakened immune system.
Why Your Dog Might Not Be Getting Enough Sleep
Understanding the cause is as important as recognising the signs. The most common reasons dogs don't get adequate sleep are:
Their rest environment isn't right. An uncomfortable, inadequately supported bed prevents dogs from reaching and maintaining deep sleep. Dogs that wake frequently due to joint discomfort, an unsuitable sleeping surface, or a bed that doesn't provide the enclosed, secure feeling their den instinct requires will accumulate sleep debt even if they spend plenty of time lying down.
The Big Snooze™ Pro Orthopedic Dog Bed addresses the two most common physical barriers to deep sleep — inadequate joint support and lack of enclosure. The deep orthopaedic foam supports the body correctly throughout sleep cycles, while the bolster walls provide the enclosed, secure environment that tells the nervous system it's safe to fully switch off. A dog that has never reached proper deep sleep on a flat, unsupported mat will often show measurable improvement in sleep quality within days of having proper support.
There's too much disturbance. Dogs love to nap but in busy households not having a safe quiet place to retreat to can be difficult for some dogs to cope with. Dogs with introvert personalities find it even harder to deal with constant activity around them and need extra time to recover from social interactions.
They're being woken up too frequently. The clearest sign your dog needs to sleep is that they are sleeping. How often do we wake our dogs up so they can participate in our plans? One of the reasons why our dogs don't sleep enough is because we don't let them.
Pain or medical conditions. Joint pain, sleep apnoea, and other medical conditions can significantly disrupt sleep quality. Flat-faced breeds (brachycephalic dogs like Bulldogs, Pugs and French Bulldogs) are particularly susceptible to breathing-related sleep disruption. If you suspect a medical issue, consult your vet.
Overstimulation. Ironically, too much exercise — particularly high-intensity exercise like fetch or agility — can produce cortisol spikes that make it harder for dogs to settle and sleep properly in the hours after. Calm decompression time after walks and high-energy activity is as important as the activity itself.
How To Improve Your Dog's Sleep Quality
Create a dedicated, undisturbed rest space. Your dog needs somewhere that is consistently quiet, familiar, and associated with rest. Once they're in their rest space, let them be — no calling them over, no engaging with them, no training. The rest space is sacred.
Establish a consistent routine. Unfamiliar or busy places, as well as unfamiliar people, can make it harder for your dog to sleep during the day. To help them get enough sleep, ensure they have periods without activities and access to quiet, familiar territory. Predictable routines tell the nervous system that rest is coming, accelerating the transition from active to settled.
Use decompression tools after stimulating activity. Scatter feeding, long-lasting chews, and lick mats immediately after walks and play help bring cortisol down and ease the transition to genuine rest. A dog that decompresses properly after activity will settle into deeper, more restorative sleep than one whose arousal level stays elevated.
The Big Snuggle™ Calming Dog Blanket plays a specific role here — familiar scent combined with the warmth and weight of a soft blanket provides a consistent sensory signal that the active phase is over and rest can begin.
Consider your dog's sleep environment carefully. Position their bed away from heavy foot traffic, road noise, and windows where passing movement might trigger vigilance. Make sure windows are covered with blackout blinds to cut down on light and shadow at night, and turn off security lights with sensors so they don't wake your dog.
Separate dogs that disturb each other. If you have multiple dogs and one consistently wakes or disturbs the other, consider separate sleeping spaces. Sleep quality matters more than co-sleeping convenience.
When To See A Vet
Not all sleep problems have behavioural solutions. If your dog shows persistent signs of sleep deprivation despite a good rest environment and consistent routine — or if they show signs of breathing disturbance during sleep (snoring, gasping, choking sounds), excessive movement or vocalisation during sleep, or sudden personality changes — a veterinary assessment is warranted.
Sleep deprivation impairs cognitive and physical performance, decreases the immune response, enhances pain sensation and increases the risk of obesity and cardiovascular disease. These are not minor quality-of-life issues — they're significant health risks that deserve proper veterinary attention if they persist.
The Bottom Line
The old saying that a tired dog is a happy dog is far from true for many dogs. The reality is that sleep-deprived dogs are often anxious, reactive, clumsy, and difficult — and their owners are often addressing the wrong problem as a result.
If your dog is sleeping 12-14 hours per day across a combination of overnight sleep and daytime naps, reaching visible deep sleep regularly, waking calmly, and maintaining consistent, predictable behaviour — they're almost certainly sleeping well.
If they're restless, reactive, clumsy, struggling to learn, or unable to settle despite adequate exercise — check the sleep before assuming anything else. A dog that hasn't slept properly in weeks will behave badly for weeks. Fix the sleep, and you might find the behaviour fixes itself.

ADVANCED FAQ
My dog sleeps all day — is that too much? Not necessarily. Dogs are polyphasic sleepers and sleeping across multiple periods throughout the day is completely normal. The concern isn't the total number of hours so much as the quality of that sleep. A dog that spends 14 hours sleeping but never reaches deep, dreaming sleep is more sleep-deprived than one sleeping 10 hours of solid, uninterrupted rest. Watch for the physical signs of deep sleep — twitching, dreaming, relaxed body — rather than counting hours alone.
My puppy sleeps constantly — should I be worried? Almost certainly not. Puppies between 8 weeks and 6 months commonly sleep 16-20 hours per day. This is completely normal and necessary for their development. Waking a sleeping puppy to interact with them is counterproductive — let them sleep. The one exception is if they seem impossible to wake, are sleeping with laboured breathing, or show other signs of illness — in those cases consult your vet.
Could my dog's bad behaviour be caused by lack of sleep? Quite possibly — and it's one of the most underconsidered explanations for reactive, difficult behaviour. Sleep deprivation produces hyperactivity, irritability, poor impulse control, heightened anxiety, and reduced learning ability — all of which look like behaviour problems when viewed in isolation. If your dog's behaviour has worsened gradually over time and you haven't changed anything about their routine, consider whether their sleep quality has declined and address that before pursuing behaviour modification.
How do I know if my dog is sleeping deeply enough? The signs of deep sleep are visible: twitching paws or legs as if running, flickering eyes behind closed lids, slight whimpering or vocalisation, irregular breathing. These are all signs of REM sleep — the deep, restorative phase where memories are consolidated and the brain and body restore themselves. A dog that always sleeps very lightly — waking instantly at the slightest sound, never showing dreaming behaviour — may not be reaching adequate deep sleep.
Does the type of dog bed affect sleep quality? Yes — significantly. Dogs that sleep on flat, unsupported surfaces without adequate cushioning often wake frequently due to joint discomfort, particularly as they age. The enclosed bolster design of orthopedic beds provides both physical support and the psychological security signal that enables the nervous system to fully stand down. Many owners report visible improvement in their dog's deep sleep quality within days of switching from a flat mat to a properly supportive enclosed bed.
