Find out exactly how much sleep your dog needs based on their age, breed size, and daily activity level — with a personalised daily schedule.
Sleep proportion relative to maximum (giant puppy = 20 hrs)
Dogs have different sleep architecture from humans. While humans spend about a third of their life asleep, dogs spend 50–65% of their day sleeping or resting. This is partly due to their polyphasic sleep pattern — dogs sleep in multiple short bursts throughout the day rather than one consolidated nighttime block. They also enter the REM (dream) phase faster than humans but spend less total time in it, meaning their sleep is less efficient per hour and they need more of it. Large breeds and working dogs used to burst activity (like wolves hunting and then resting) are especially prone to long rest periods.
Most dogs sleep 12–14 hours per day, and puppies and seniors commonly sleep 16–20 hours. Sudden changes in sleep pattern are more concerning than total hours. Signs that excess sleep may indicate a health problem include: reluctance to get up when called, sleeping through meals, no interest in walks they previously enjoyed, or sleep accompanied by difficulty breathing, restlessness, or unusual noises. If your dog's sleep has recently increased significantly, a vet check-up is warranted. Conditions like hypothyroidism, Addison's disease, anemia, and pain can all cause increased sleep.
Yes. During REM sleep, dogs show the same brain wave patterns as humans during dreaming, including twitching, leg paddling, soft vocalisations, and eye movement. Studies by Dr. Matthew Walker and others have shown dogs likely replay memories of their day — particularly play sessions and learning tasks. Puppies and senior dogs typically enter REM more frequently than adult dogs. If your dog twitches in sleep, this is completely normal and should not be interrupted — the old advice about not waking sleeping dogs applies here.
Research on dog-human co-sleeping is nuanced. A 2017 Mayo Clinic study found that dogs sleeping in the bedroom (but not in the bed) did not disrupt human sleep quality, while in-bed sleeping was more disruptive. For dogs, sleeping in proximity to their human "pack" is generally reassuring and helps reduce separation anxiety. The most important factors are: comfort (appropriate bedding), temperature (most dogs prefer 16–22°C), and routine consistency — dogs thrive on predictable sleep schedules just as humans do.
Unlike human children, dogs do not generally need to be kept awake during the day to sleep at night. Their polyphasic sleep pattern means daytime napping doesn't usually affect overnight sleep. However, if your dog is sleeping poorly at night, ensuring adequate physical and mental stimulation during the day — particularly in the late afternoon — can improve overnight rest. Puzzle feeders, training sessions, and walks in the 2–5pm window are most effective.
