How Much Do Dogs Sleep? Real Numbers by Age

The “dogs sleep 14 hours a day” answer is too vague. Sleep need varies dramatically by age, size, activity, and health.

Expected Sleep Hours by Age

Giant breeds (Newfoundland, St Bernard, Great Dane) sleep more (+1.5h baseline). Working dogs sleep less (-1h). Active sport dogs typical 12-13h. Sedentary dogs sometimes 15-17h.

Dog Sleep Architecture

Different from humans:

• 65% drowsy / light sleep (easily roused — evolutionary alertness)
• 23% deep slow-wave sleep (restorative)
• 10-12% REM sleep (vs 20-25% humans)
• REM cycles every 20 minutes (vs 90 in humans) — hence frequent dreaming/twitching

Night sleep: 55-60% of total, typically 8-10pm to 6-7am. Daytime naps: 40-45%, multiple short naps after walks, meals, play.

When to Worry

Sudden Increase (2-3h beyond baseline)

• Hypothyroidism (T4/TSH testing)
• Anaemia (CBC)
• Cardiac disease (echo)
• Infection (CRP, fever)
• Pain (multimodal exam)
• Depression-like presentation (often from boredom/insufficient enrichment)
• Hepatic encephalopathy (bile acids)

Sudden Decrease + Restlessness

• Anxiety
• Cognitive dysfunction syndrome (CCD) — classic in seniors
• Pain
• Cushing’s
• Hyperthyroidism (rare in dogs)

Night Waking + Pacing (Senior)

CCD until proven otherwise. Prevalence 14% at 8y, 28% at 11-12y, 40%+ at 15+.

DISHAA framework: Disorientation, Interaction changes, Sleep-wake cycle, House-soiling, Activity changes, Anxiety/learning decline.

Treatment:

• Selegiline (Anipryl) 0.5-1 mg/kg q24h — licensed, ~50-70% response
• Antioxidant diets (Hill’s b/d, Purina Bright Mind, Royal Canin Mature)
• Omega-3 100 mg/kg
• Melatonin 0.1 mg/kg evening for sleep-wake
• MCT oil 1-9% of calories

Always rule out treatable contributors first: sensory loss, pain, hypothyroid, Cushing’s, hepatic encephalopathy, CKD, brain tumour.

Excessive Twitching That Doesn’t Rouse

Normal REM twitching stops with gentle touch. Persistent twitching that doesn’t respond to gentle rousing = potential seizure activity. Record on video for vet.

Loud Snoring + Breathing Difficulty

• BOAS in brachycephalic breeds
• Laryngeal paralysis in senior Labs/Goldens
• Sleep-disordered breathing causes oxygen desaturation and long-term cardiac strain

Waking With Cries of Pain

• IVDD
• Arthritis
• Dental disease
• Otitis externa

Bed-Wetting (Previously Housetrained)

• Hormone-responsive incontinence (spayed females, USMI)
• UTI
• Diabetes / CKD (polyuria)

Sleep Hygiene for Dogs

• Consistent schedule — same bedtime each night
• Quiet dark space — many prefer crate or covered bed
• Orthopaedic bed for seniors (memory foam game-changer)
• Temperature 18-21°C / 65-70°F — brachys may need warmth, double-coats cooler
• Exercise earlier in day — not right before bed
• Last meal 3-4h before bed
• Last toilet 30 min before bedtime
• White noise / fan for sensitive dogs in noisy households

Conclusion

Dogs sleep more than people think — 12-14h is normal for adults, 16-22h for puppies and geriatrics. Sleep architecture differs from humans — 20-minute REM cycles cause frequent dreaming/twitching. Sudden sleep changes in either direction warrant a vet visit; night waking and pacing in seniors is cognitive dysfunction syndrome until proven otherwise (and very treatable). Sleep hygiene matters — consistent schedule, quiet space, orthopaedic bed for seniors, temperature comfort.

Frequently Asked Questions

How many hours a day do dogs sleep?

DEPENDS ON AGE. NEWBORN/YOUNG PUPPY (under 3 months) – 20-22 hours/day (critical for growth + brain development). YOUNG PUPPY (3-6 months) – 18-20 hours. PUPPY (6-12 months) – 16-18 hours. ADOLESCENT (1-2 years) – 14-16 hours. ADULT (2-7 years) – 12-14 hours. SENIOR (7-10 years) – 14-16 hours. GERIATRIC (10+) – 16-20 hours. GIANT BREEDS sleep more than smaller dogs (+1.5h baseline). WORKING DOGS sleep less when working. ACTIVE SPORT DOGS typical 12-13h. INDIVIDUAL VARIATION is normal – some dogs naturally sleep more or less. CONCERNING – sudden change of 2-3 hours either direction warrants vet visit (treatable causes include hypothyroidism, anaemia, cardiac disease, infection, depression, pain, cognitive dysfunction in seniors).

Why does my dog twitch in his sleep?

NORMAL REM SLEEP ACTIVITY. Dogs experience REM (Rapid Eye Movement) sleep cycles every ~20 minutes (vs every 90 min in humans), making them dream more frequently and visibly. NORMAL TWITCHING during REM includes: paw movements, leg running motions, facial twitches, whimpers, growls, tail wags, eye movements under closed lids, sometimes yips/barks. The dog is DREAMING – brain replaying experiences during memory consolidation. NORMAL TWITCHING stops if you gently touch or call the dog (they wake briefly then resettle). PUPPIES and SENIORS dream most actively. CONCERNING TWITCHING that warrants vet/video: 1) Doesn’t stop with gentle rousing; 2) Lasts more than 1-2 minutes; 3) Includes vocalization that sounds distressed/painful; 4) Includes urination/defecation; 5) Followed by post-ictal confusion/disorientation when fully waking; 6) Stiff full-body rigidity vs normal twitching. RECORD on phone video – extremely helpful for vet to distinguish dream activity from focal seizures. NORMAL twitches = small body parts independently moving briefly; SEIZURES = synchronized rhythmic movements often whole-body.

Is it normal for my senior dog to sleep all day?

DEPENDS ON CHANGE FROM BASELINE. Senior dogs (7+ years size-dependent) naturally sleep MORE than younger adults – 14-20 hours/day is normal range, vs 12-14 hours in 2-7 year olds. GRADUAL INCREASE over years as dog ages is expected. CONCERNING if: 1) SUDDEN increase of 2-3 hours beyond previous baseline; 2) Difficulty waking, lethargy when awake; 3) Loss of interest in activities previously enjoyed; 4) Decreased appetite + increased sleep; 5) Weight loss with increased sleep. RULE OUT MEDICAL CAUSES with senior wellness check: HYPOTHYROIDISM (T4/TSH/cholesterol); ANAEMIA (CBC); CARDIAC DISEASE (echo, NT-proBNP); CKD (BUN/creatinine/SDMA/USG/UPC); LIVER DISEASE (ALT/ALP/bile acids); CUSHING’S (ACTH stim/LDDS); INFECTION (CRP, fever); PAIN from arthritis/dental/IVDD often UNDER-RECOGNIZED in seniors; CANCER especially lymphoma/hemangiosarcoma/osteosarcoma. ALSO RULE OUT environmental causes – reduced exercise opportunity, social isolation, depression after loss of companion (human or dog), pain causing reduced activity. Multimodal pain management often dramatically improves senior ‘sleepy/sluggish’ dogs.

Why is my puppy sleeping so much?

PERFECTLY NORMAL. Puppies need MASSIVE amounts of sleep for growth and brain development. NEWBORN to 3 months: 20-22 hours/day. 3-6 months: 18-20 hours. 6-12 months: 16-18 hours. Critical for: PHYSICAL GROWTH (growth hormone released during deep sleep); BRAIN DEVELOPMENT (memory consolidation, neural pruning); IMMUNE SYSTEM development; learned behavior reinforcement. PUPPY SLEEP PATTERN – short awake bursts of high energy (zoomies, training, play) followed by long naps; multiple naps throughout day not one long sleep period. OVER-TIRED puppies often act ‘crazy’ or ‘wired’ – paradoxical reaction; they need MORE sleep not stimulation. SET A NAP SCHEDULE – structured rest after meals and walks; crate training helps establish nap routine. WAKING A PUPPY for training/socialization should be limited – prioritize sleep. CONCERNING if puppy: 1) Difficult to rouse for meals/elimination; 2) Pale gums when sleeping; 3) Sleep + diarrhoea/vomiting (parvo? hypoglycaemia in toy breeds?); 4) Sleep + cough/discharge (kennel cough, distemper); 5) Twitching that doesn’t respond to gentle touch. NORMAL – hard to wake immediately after eating; deep nap mid-day.

What does it mean when my senior dog wakes up at night and paces?

COGNITIVE DYSFUNCTION SYNDROME (CCD) IS CLASSIC PRESENTATION. Also known as canine Alzheimer’s, CCD prevalence 14% at 8 years, 28% at 11-12 years, 40%+ at 15+. DISHAA FRAMEWORK screening – DISORIENTATION (getting stuck in corners, looking confused in familiar places), INTERACTION CHANGES (less greeting, less affection seeking), SLEEP-WAKE CYCLE disturbance (THIS – day-night reversal, night waking and pacing, daytime sleeping more), HOUSE-SOILING (regression in toilet training), ACTIVITY CHANGES (less active, or compulsive repetitive activity), ANXIETY/LEARNING decline (new fears, forgetting commands). SUNDOWNING pattern – confusion + agitation in evening hours. TREATMENT – SELEGILINE (Anipryl) licensed 0.5-1 mg/kg q24h with ~50-70% response in 4-6 weeks; ANTIOXIDANT DIETS (Hill’s b/d, Purina Bright Mind, Royal Canin Mature) with DHA/EPA/MCT oil/L-carnitine; OMEGA-3 100 mg/kg/day; MELATONIN 0.1 mg/kg evening for sleep-wake regulation; MCT OIL 1-9% of calories; SENILIFE/NEUTRICKS supplements. RULE OUT FIRST other treatable causes – sensory loss (blindness, deafness causing disorientation), PAIN (arthritis driving restlessness), HYPOTHYROIDISM, CUSHING’S, HEPATIC ENCEPHALOPATHY, CKD, BRAIN TUMOUR (MRI if rapidly progressive). EARLIER intervention has better outcomes – don’t dismiss as ‘just old age’.

Should I let my dog sleep in bed with me?

PERSONAL CHOICE – NO UNIVERSAL ANSWER. PROS: bonding, comfort for dog and human, can help anxious dogs settle, warm sleep buddy. CONS/CONSIDERATIONS: ALLERGIES – sharing bed worsens allergic symptoms in 40% of allergic humans; ASTHMA particularly. HYGIENE – dogs bring outdoor debris, parasites (fleas, ticks), bacterial colonization onto bedding; consider parasite prevention strict, regular grooming, bath schedule. SLEEP DISRUPTION – if dog disrupts your sleep with movement, snoring, or temperature regulation, your sleep quality may suffer; insomnia in humans worsens with disrupted sleep. RESOURCE GUARDING risk – some dogs develop possessiveness of bed; cardinal not to allow if any growling/snapping signs. SMALL CHILDREN consideration – some breeds protective of bed and may resource-guard against children. JOINT ISSUES in older dogs benefit from orthopaedic dog bed not human bed. STUDY FINDINGS: Mayo Clinic 2017 found having dog IN BEDROOM (own bed) improved sleep; having dog IN BED slightly worsened sleep efficiency. RECOMMENDATIONS: 1) If you sleep poorly with dog in bed, consider dog bed in bedroom; 2) Maintain strict parasite prevention; 3) Wash bedding weekly; 4) Establish clear expectations early – changing rules later confuses dog; 5) Set rules for when dog must leave bed (your sleep partner, children visiting, dog illness). NO CONCERN if both you and dog sleep well together – this is centuries-old human-dog co-evolution.
