Key points:
- Dogs spend a significant portion of each day sleeping and resting.
- Puppies generally need the most sleep to support their rapid growth and development.
- Senior dogs may also sleep more as their energy levels and activity needs change.
- Breed, age, activity levels, health and environment can all influence how much a dog sleeps.
- Sudden changes in sleeping habits, energy or restlessness are worth discussing with your vet.
- Regular exercise, a consistent routine and a comfortable sleep space can support better-quality rest.
Given how energetic dogs can be, it’s little wonder owners can forget how much time they spend sleeping each day.
The truth is, dogs of all ages can spend a significant part of the day resting. Dog sleep is a critical part of their routine, supporting their overall health and behaviour.
Read on to learn how much sleep dogs need at different life stages, what can affect their rest, when changes may warrant a vet visit, and how to support better-quality sleep.
How many hours do dogs sleep?
So, how many hours do dogs sleep? Well, many adult dogs spend around 12 to 16 hours sleeping or resting each day, although individual needs vary.
If your dog’s sleep seems off, keep a simple log for a few days noting when they nap, how long they sleep and whether they seem restless. It can make changes in their usual routine easier to spot.
Age, breed, size, health and activity levels can all influence how long dogs sleep, so it’s helpful to become familiar with what’s normal for your dog.
Sleep needs by life stage
Outside of adult dogs, puppies and senior dogs generally spend more time sleeping.
If you’re wondering how much sleep a puppy needs, young puppies can spend much of the day asleep as their bodies and brains develop. Their puppy sleep needs are higher than those of adult dogs because sleep supports growth and helps them process what they learn while awake.
Most senior dogs also tend to sleep more as they age. Lower energy levels, reduced activity and health or mobility changes can all influence their dog sleep patterns.
What affects how much your dog sleeps?
There are a few key factors that affect how much and how well your dog sleeps:
Breed and size: Individual sleep needs vary, and some breeds and larger dogs may naturally spend more time resting than others.
Activity level and exercise: Dogs that get suitable physical exercise and mental stimulation throughout the day may find it easier to settle and rest.
Health conditions: Conditions such as arthritis or hip dysplasia can disrupt sleep if your dog finds it uncomfortable to stay in one position for long.
Environment: Noise, excessive heat or cold, and frequent foot traffic around their resting area can affect the quality of their sleep.
When to be concerned about your dog's sleep
The main time to pay attention to your dog’s sleeping behaviour is when you notice a sudden or significant change. Consider booking a vet check-up if you notice:
Changes in how often your dog lies down to sleep
Significant changes in the length of their sleep
Excessive lethargy while awake
Trouble settling to sleep
Increased restlessness
Changes in sleep can sometimes be linked to pain or other health concerns, so note what has changed and how long it has been happening to give your vet clearer context.
Helping your dog get good-quality rest
There are several steps you can take to support a healthy dog sleep cycle.
When dogs are awake, they benefit from appropriate physical activity and mental stimulation. Walks, play, training and opportunities to sniff and explore can all help keep them engaged during the day and support restful sleep.
Exercise needs vary considerably by age, breed and health. Puppies need age-appropriate, low-impact activity while their bones and joints are developing, while senior dogs may benefit from shorter, gentler sessions. Follow your dog’s cues and speak with your vet if you’re unsure how much activity is suitable.
Much like humans, dogs can also benefit from consistent routines. Aim to keep walks, play, meals and rest periods relatively predictable to help establish healthy dog sleeping habits.
Finally, make sure your dog has a comfortable bed suited to their size and age, positioned in a quiet area where they can rest without being regularly disturbed.
