How many hours should your dog sleep? Most adult dogs sleep about 11 to 14 hours a day, puppies need considerably more, and seniors usually land around 12 to 15. This free dog sleep calculator turns your dog’s age, size, and routine into a daily sleep range, splits it into night sleep and daytime naps, and checks whether your dog’s actual sleep looks typical.
11–14 Hours
Typical daily sleep for a healthy adult dog
18–20 Hours
Common guidance for young puppies, spread over many naps
12–15 Hours
Typical range for most senior dogs
Up to 18 Hours
Some large and giant breeds sleep this much, even in middle age
20+ Hours
Sleeping this much may point to a medical issue worth a vet visit
Polyphasic
Dogs sleep in many short bouts, not one long night like people
Quick answer: Adult dogs typically sleep about 11 to 14 hours per 24 hours, puppies about 18 to 20, and seniors about 12 to 15. Large and giant breeds tend to sleep more. If your dog sleeps more than roughly 20 hours a day, or their sleep pattern changes suddenly, talk to your vet.
Sleep is not a luxury for dogs. It supports growth, learning, mood, and recovery, and it changes with age, size, and health. Before you try the calculator, it helps to know your dog’s life stage, which our dog age calculator works out in human years and life stages. Sleep also depends on how your dog spends the rest of the day, so see how much activity they need with the dog exercise calculator, and how long they can comfortably be left on their own with the dogs alone time calculator.
Free Dog Sleep Calculator: How Many Hours Should Your Dog Sleep?
Choose your dog’s life stage and size, then add how many hours they actually sleep and anything unusual you have noticed. The calculator shows a typical range, a night and nap split, and a plain-language check on your dog’s current sleep.
How Much Sleep Does a Dog Need? (By Age)
The numbers you see online vary because the research is limited and owners measure sleep differently. Popular guidance, including figures cited by the American Animal Hospital Association, puts puppies at 18 to 20 hours and adults at 12 to 14. Some measured studies find lower totals, with puppies at about 11 hours or more and adults between about 8 and 13.5 hours with an average just under 11, as summarized by the Sleep Foundation. Our calculator uses ranges that sit across both views and flags only the extremes.
| Life Stage | Typical Sleep per 24 Hours | What to Expect |
|---|---|---|
| Newborn to 8 weeks | Most of the day | Wakes mainly to nurse and warm up with the litter. |
| Puppy, 8–12 weeks | 18–20 hours | Short bursts of play followed by deep naps; frequent potty breaks at night. |
| Puppy, 3–6 months | 16–18 hours | Longer awake windows and a growing night block. |
| Puppy, 6–12 months | 14–16 hours | Teenage energy; sleep still supports rapid growth and learning. |
| Adult (1–7 years) | 11–14 hours | Mostly night sleep plus several daytime naps. |
| Senior (about 7–10+ years) | 12–15 hours | More frequent naps; large and giant seniors may sleep more. |
| Older senior (11+ years) | 13–16 hours | Lighter, more broken sleep is common; comfort and routine matter. |
Which row applies depends on your dog’s size and breed, because giant breeds reach their senior years earlier than small dogs. If you are unsure, use the dog age calculator to see your dog’s life stage, and the puppy age calculator on that page to convert weeks into months.
Do Big Dogs Sleep More? Dog Sleep by Size
Generally yes. According to the American Kennel Club, large and giant breeds tend to sleep more than small breeds, and some can sleep up to about 18 hours a day even in middle age. The table shows the adult ranges used in our calculator. Individual dogs vary, so treat these as starting points.
| Adult Size | Typical Adult Sleep | Typical Senior Sleep | Example Breeds |
|---|---|---|---|
| Small (up to 20 lbs) | 11–14 hours | 12–15 hours | Chihuahua, Yorkshire Terrier, Pomeranian, Dachshund |
| Medium (21–50 lbs) | 11–14 hours | 12–15 hours | Beagle, Cocker Spaniel, Border Collie, Corgi |
| Large (51–100 lbs) | 12–15 hours | 13–16 hours | Labrador, Golden Retriever, German Shepherd, Boxer |
| Giant (over 100 lbs) | 13–16 hours | 14–17 hours | Great Dane, Saint Bernard, Mastiff, Bernese Mountain Dog |
Weight can also affect sleep quality. Extra body weight makes breathing and joint comfort harder, which can break up rest, so check your dog’s condition with the dog weight calculator and portions with the dog calorie calculator.
Dog Sleep Patterns by Breed
There are no reliable per-breed hour counts, so the table below lists 31 popular breeds with their size group and a general sleep pattern based on size, energy, and known health traits. Treat it as a guide to what to watch for, not a prediction. Flat-faced breeds and a few breeds with inherited sleep conditions deserve extra attention, as the Sleep Foundation notes for sleep apnea and narcolepsy.
| Breed | Size | General Sleep Pattern | Notes |
|---|---|---|---|
| Chihuahua | Small | Typical | Likes warm, burrowed sleeping spots. |
| Yorkshire Terrier | Small | Typical | Light, easily woken sleeper; likes a cozy bed. |
| Pomeranian | Small | Typical | Alert; may nap in short bursts. |
| Dachshund | Small | Typical | Burrower; choose a supportive surface for the long back. |
| Jack Russell Terrier | Small | Typical | High energy, then deep sleep after exercise. |
| Shih Tzu | Small | Flat-faced: watch breathing | Snoring is common; report loud or labored breathing. |
| Pug | Small | Flat-faced: watch breathing | Prone to snoring and sleep-disordered breathing. |
| French Bulldog | Small | Flat-faced: watch breathing | Keep sleeping areas cool; breathing can be noisy. |
| Boston Terrier | Small | Flat-faced: watch breathing | Snoring and overheating are common concerns. |
| English Bulldog | Medium | Flat-faced: watch breathing | Sleeps a lot; breathing problems can fragment sleep. |
| Beagle | Medium | Typical | Nose-driven; naps hard after long sniff walks. |
| Cocker Spaniel | Medium | Typical | Affectionate; often sleeps close to family. |
| Pembroke Welsh Corgi | Medium | Typical | Light sleeper that can be alert to household noise. |
| Border Collie | Medium | Alert, needs a wind-down | Struggles to settle without mental and physical exercise. |
| Australian Shepherd | Medium | Alert, needs a wind-down | Needs a job and exercise to sleep soundly. |
| Australian Cattle Dog | Medium | Alert, needs a wind-down | Restless when under-stimulated. |
| Siberian Husky | Medium | Typical | Prefers cool sleeping spots; heat disrupts rest. |
| Basset Hound | Medium | Often sleeps more | Relaxed; weight control helps sleep and joints. |
| Labrador Retriever | Large | Typical to more | Can inherit narcolepsy in some lines; watch weight. |
| Golden Retriever | Large | Typical to more | Naps hard after exercise; watch joints in seniors. |
| German Shepherd | Large | Typical | Light, watchful sleeper; hip and joint comfort matters. |
| Boxer | Large | Short-faced: watch breathing | Can overheat and snore; keep sleeping areas cool. |
| Doberman Pinscher | Large | Typical | Narcolepsy can be inherited in the breed. |
| Rottweiler | Large | Typical to more | Sleeps heavily after exercise; supportive bed helps joints. |
| Greyhound | Large | Often sleeps more | Famous for long naps; thin coat, so provide a warm bed. |
| Bernese Mountain Dog | Giant | Often sleeps more | Prefers cool spots; needs joint-friendly bedding. |
| Great Dane | Giant | Often sleeps more | Needs a large, orthopedic bed. |
| Saint Bernard | Giant | Often sleeps more | Heat-sensitive; provide cool, shaded sleeping areas. |
| Mastiff | Giant | Often sleeps more | Sleeps a lot; watch breathing and joints. |
| Newfoundland | Giant | Often sleeps more | Prefers cool areas; thick coat traps heat. |
| Irish Wolfhound | Giant | Often sleeps more | Needs soft support for long limbs and joints. |
Dog Sleep Cycles, REM, and Dreams
Dogs are polyphasic sleepers, which means they sleep in many short periods across the day and night rather than in one long block, and they cycle between slow-wave and REM sleep repeatedly. Puppies spend a larger share of their sleep in REM than adults, which fits with their brains consolidating new learning. That is why a dog can look wide awake one minute and be deeply asleep the next.
| Stage | What You See | What It Means |
|---|---|---|
| Awake and Alert | Eyes open, ears moving, ready to respond. | Active time for play, walks, and training. |
| Resting or Dozing | Lying down, relaxed, eyes half open, easily roused. | Light rest that is not true deep sleep but still helps recovery. |
| Slow-Wave Sleep | Still, slow steady breathing, hard to wake. | Deeper sleep thought to support physical rest and recovery. |
| REM Sleep | Twitching, paddling legs, whimpers, soft barks, quick eye movement under the lids. | Associated with dreaming, memory processing, and learning. |
Twitching and paddling during REM are normal and usually brief. As a rule, let sleeping dogs lie, and if you must wake a dreaming dog, call their name softly rather than touching them, since a startled dog can react defensively. Shallow, quick breathing with continuous twitching when your dog lies down may mean they are not resting deeply, and quality matters as much as quantity.
Dog Sleeping Positions and What They Might Mean
Sleeping positions are popular to decode, but they are loose interpretations rather than settled science. Use them as clues together with temperature, comfort, and your dog’s usual habits.
| Position | Common Interpretation | Things to Consider |
|---|---|---|
| Curled Up (Donut) | Conserving warmth and protecting the belly. | Common in cooler rooms and with thin-coated dogs; offer a warm bed. |
| On the Side | Relaxed and comfortable. | Often a sign of deep, trusting rest. |
| On the Back, Belly Up | Very relaxed, or cooling off. | Exposes the belly, which has less fur and cools quickly in warm rooms. |
| Superman or “Sploot” | Ready to jump up, or stretching the hips. | Common in puppies and playful dogs; usually harmless. |
| Head on Paws or Chin Propped Up | Resting but ready to respond. | Often light dozing rather than deep sleep. |
| Pressed Against You or Another Pet | Seeking closeness and warmth. | In a study reported by AAHA, about 87% of puppies and 63% of adult dogs chose to sleep near people. |
| Burrowed in Blankets | Seeking a secure, den-like feeling. | Provide a bed with sides or a covered crate, and watch for overheating. |
Puppy Sleep Schedule: Naps, Nights, and Overtired Puppies
Puppies run on short cycles: play, snack, potty, nap, repeat. The AAHA notes that an overtired puppy can look like an overtired toddler, with evening mouthing, grabbing things, and trouble settling, so protecting naps is part of training. The schedule below is a general pattern, and your vet’s guidance and your puppy’s own cues come first.
| Puppy Age | Typical Sleep | Awake Window | Night Pattern |
|---|---|---|---|
| 8–12 weeks | 18–20 hours | About 1–2 hours | Often 6–8 hours with at least one potty break. |
| 3–6 months | 16–18 hours | About 2 hours | Often 7–9 hours, with fewer night breaks. |
| 6–12 months | 14–16 hours | About 2–3 hours | Often 8–9 hours, close to an adult pattern. |
Signs your puppy needs a nap include yawning, sudden zoomies and mouthiness, lying down mid-play, and ignoring cues they usually know. Place a crate or bed in a quiet spot, take your puppy out to potty before sleep, and keep naps as undisturbed as possible. Use the puppy age calculator in our dog age calculator to turn weeks into months, and keep play age-appropriate with the dog exercise calculator.
How Much Sleep Does a Senior Dog Need?
The AKC reports that most senior dogs need about 12 to 15 hours of sleep a day, and that large and giant seniors may sleep more. Napping more is normal, but disrupted nights, new hiding spots, or restlessness are not. Conditions the AKC links to excess sleep include canine cognitive disorder, arthritis or pain, kidney disease, hypothyroidism, heart disease, and some cancers, so a vet check is worthwhile when a change appears.
| Change You Notice | Possible Reasons | Helpful Step |
|---|---|---|
| Sleeping More, Eating Normally | Normal aging, lower energy, or hot weather. | Keep routine check-ups and monitor appetite, mobility, and alertness. |
| Pacing or Vocalizing at Night | Pain, anxiety, or cognitive decline. | Tell your vet; ask about pain relief and cognitive support. |
| Day and Night Reversed | Cognitive decline or discomfort. | Keep daytime activity, light exposure, and a calm evening routine. |
| Trouble Getting Comfortable | Arthritis or joint pain. | Orthopedic bedding, non-slip floors, and a vet pain assessment. |
| Not Waking to Sounds | Hearing loss. | Wake your dog gently with a light touch and mention it to your vet. |
| Drinking and Urinating More at Night | Kidney, endocrine, or other conditions. | Never restrict water; compare intake with the water intake calculator for dogs and call your vet if it stays high. |
Is My Dog Sleeping Too Much or Too Little?
Total hours matter less than change and context. A 2022 survey of 1,330 owners reported in AAHA Trends linked both fewer than eight hours and more than ten hours of household-hours sleep with higher problem-behavior scores, and dogs that were easily startled awake by household noise fared worse than total hours alone predicted. Use these signs to decide whether to simply adjust the routine or call your vet.
| Situation | Often Harmless If | See Your Vet If |
|---|---|---|
| Sleeping a Lot | Eating well, moving comfortably, and alert when awake; common in big dogs, hot weather, and boring days. | Sleeping more than about 20 hours a day, or a sudden jump from their normal. |
| Sleeping Little | Energetic, relaxed, and calm during the day. | Restless, panting, pacing, or unable to settle, which may mean pain or anxiety. |
| Snoring | Occasional and quiet, especially in flat-faced dogs. | Loud, new, or paired with gasping, pauses, or daytime sleepiness. |
| Twitching or Barking in Sleep | Brief, during relaxed REM sleep. | Violent thrashing, trouble waking, or distress. |
| Night Waking | Short bathroom trips or a new environment. | Frequent waking with pacing, whining, or confusion. |
| Collapsing Into Sleep | Never normal while active or excited. | Any sudden collapse; seek veterinary care promptly. |
Over 20 Hours a Day
Sleeping this much may point to an underlying condition and deserves a vet exam.
Sudden Change
A fast shift in sleep, appetite, or activity matters more than any average.
Labored Breathing
Gasping, long pauses, or fast, effortful breathing during sleep needs prompt veterinary attention.
Common Dog Sleep Problems and Disorders
Only a veterinarian can diagnose a sleep problem, but knowing the names and signs helps you describe what you see. A short phone video of the behavior is often very helpful at the appointment.
| Problem | Signs | Who Is More at Risk |
|---|---|---|
| Sleep Apnea or Sleep-Disordered Breathing | Loud snoring, gasping, restlessness, and daytime sleepiness. | Flat-faced breeds such as Bulldogs and Pugs, and overweight dogs. |
| Narcolepsy | Sudden collapse into sleep, often during excitement or eating. | Can be inherited in breeds such as Doberman Pinschers and Labrador Retrievers. |
| REM Sleep Behavior Disorder | Abnormal or violent movements during REM sleep. | Reported in dogs of different ages; needs veterinary assessment. |
| Canine Cognitive Dysfunction | Night pacing, vocalizing, confusion, and reversed day and night. | Mostly older dogs. |
| Pain or Arthritis | Trouble settling, frequent position changes, and stiffness on waking. | Senior dogs, large breeds, and overweight dogs. |
| Anxiety | Panting, pacing, and difficulty settling alone or at night. | Dogs with separation or noise sensitivities. |
What Affects How Much and How Well Dogs Sleep?
| Factor | How It Affects Sleep | What You Can Do |
|---|---|---|
| Age | Puppies and seniors sleep more than adults. | Match expectations to life stage using the dog age calculator. |
| Exercise and Mental Work | Too little leaves dogs restless, while too much can leave them sore or overtired. | Get the right amount with the dog exercise calculator and add scent games and training. |
| Time Alone | Long stretches alone can mean boredom sleep or anxious, broken rest. | Plan breaks and enrichment using the dogs alone time calculator. |
| Diet and Weight | Overweight dogs often sleep poorly and tire quickly; hunger can wake dogs early. | Review portions with the dog calorie calculator and check condition with the dog weight calculator. |
| Temperature | Heat disrupts sleep, especially in thick-coated and flat-faced dogs. | Keep the sleeping area cool, ventilated, and shaded, with fresh water within reach. |
| Noise and Light | Dogs easily woken by household noise tend to have more problem behavior. | Choose a quiet spot, reduce sudden noise, or use gentle white noise. |
| Bed and Location | A bed that is too small, hard, or in a drafty spot reduces rest. | Use a supportive bed in a calm area; many dogs prefer to sleep near family. |
| Health and Pain | Pain, itching, and illness break up sleep. | Treat the cause with your vet and use orthopedic bedding for sore joints. |
How to Help Your Dog Sleep Better
Small routine changes make a big difference to sleep quality. Try these steps and give each a week or so before judging the results:
Keep a Consistent Routine:
Feed, walk, and go to bed at similar times each day. Dogs thrive on predictable rhythms.
Exercise Earlier, Wind Down Later:
Do the most energetic activity earlier in the evening, then switch to calm sniffing, a slow walk, or a chew in the last hour.
Give a Final Potty Break:
Take your dog out right before bed, and plan a night break for young puppies and seniors.
Create a Comfortable Sleep Space:
Choose a right-sized, supportive bed in a quiet, draft-free, comfortably cool spot, ideally near the family.
Reduce Disturbances:
Limit sudden noises and bright lights at night, and consider gentle background sound if outside noise wakes your dog.
Avoid Big Meals Right Before Bed:
Ask your vet about the best feeding schedule, especially for deep-chested breeds and dogs with digestive issues.
Protect Puppy Naps and Senior Comfort:
Let puppies sleep undisturbed, and give seniors orthopedic bedding, ramps, and non-slip floors.
Frequently Asked Questions
Most adult dogs sleep about 11 to 14 hours in a 24-hour day. Puppies need more, often 18 to 20 hours by common guidance, and senior dogs usually sleep about 12 to 15 hours. Size, breed, activity, and health all shift the total, so use the calculator for a range that fits your dog.
Young puppies commonly sleep 18 to 20 hours a day, spread across many naps, and the total gradually falls as they grow. Some studies measure lower totals, so a healthy, growing puppy that sleeps a little less is not automatically a concern. Overtired puppies often become mouthy, wired, and hard to settle.
Often yes. Large and giant breeds generally sleep more than small breeds, and some sleep up to about 18 hours a day even in middle age. Breed, energy level, and age still matter, so compare your dog with the range for their size and watch for changes from their own normal.
Dogs are daytime nappers, and many sleep a lot when their owners are busy or away. Sleeping a lot is usually fine if your dog eats well, moves comfortably, and responds normally when awake. Sleeping more than about 20 hours a day, or a sudden change in sleep habits, appetite, or energy, is worth a vet visit. If your dog is alone for long stretches, the dogs alone time calculator can help you plan a healthier day.
Twitching, paddling, and soft barking usually happen during REM sleep, when dogs are thought to dream. It is normal and brief. If your dog thrashes violently, has trouble waking, or seems distressed, mention it to your vet, since a few sleep disorders cause abnormal movement during REM sleep.
Most senior dogs sleep about 12 to 15 hours a day, and large or giant seniors may sleep more. Nighttime pacing, confusion, or a reversed day and night pattern can signal cognitive decline or pain, so raise those with your vet instead of assuming it is just age.
Yes. A 2022 owner survey reported in AAHA Trends found that dogs sleeping fewer than eight hours during household hours had higher problem-behavior scores, and dogs that were easily woken by household noise scored worse than total hours alone would predict. A calm, quiet, comfortable sleep spot helps.
Behind the Research: How We Built This Dog Sleep Calculator & Guide
At Mondo Paws, our mission is to empower pet owners with scientifically accurate, veterinary-reviewed tools. To create this calculator and sleep guide:
- Reconciled Conflicting Sleep Figures: Published guidance gives different totals, with popular figures of 18 to 20 hours for puppies and 12 to 14 for adults, and some measured studies finding lower numbers. The calculator uses ranges that sit across both and only flags extremes. Results are general estimates, not diagnoses.
- Cross-Referenced Veterinary and Sleep Sources: Hours by age and size, sleep behavior, and warning signs were checked against the American Animal Hospital Association, the American Kennel Club, and the Sleep Foundation.
- Compiled Breed Sleep Overview: Summarized general sleep patterns and health notes for 31 popular breeds, based on size, energy, and known sleep-related conditions. Per-breed hour counts are not reliably measured, so none are claimed.
Final Thoughts
Good sleep keeps your dog healthy, calm, and ready to learn. Use the Dog Sleep Calculator as a starting range, then build the rest of the day around it: match activity with the dog exercise calculator, confirm life stage with the dog age calculator, and plan time at home with the dogs alone time calculator.
Remember that your dog’s own normal is the best benchmark. If sleep changes suddenly, runs past about 20 hours a day, or comes with snoring, pacing, confusion, labored breathing, or a drop in appetite or energy, contact your veterinarian rather than waiting to see if it passes.
