Why Do Dogs Sleep So Much – Dog Sleeping Habits
If you’ve ever caught your dog snoozing for the fifth time before noon, you may have asked yourself: Why do dogs sleep so much? Compared to humans, who typically need 7–9 hours of sleep a night, dogs can clock in anywhere from 12 to 18 hours of sleep per day. That’s a lot of shut-eye! But before you worry, know this: excessive sleep in dogs is usually completely normal.
Let’s explore why our furry companions sleep so much and what factors influence their sleeping habits.
1. Dogs Have Different Sleep Cycles
Dogs don’t sleep the same way humans do. While we experience long periods of deep sleep, dogs have shorter sleep cycles and spend more time in lighter stages of sleep. This means they need to sleep more frequently to feel rested. You’ll often notice dogs napping on and off throughout the day, rather than getting all their rest in one go.
2. Age Plays a Big Role
Just like with humans, age affects how much sleep a dog needs:
- Puppies: These little energy bombs need tons of rest, up to 18–20 hours a day! Growing, learning, and processing new experiences takes a lot out of them.
- Adult Dogs: Most adult dogs sleep around 12–14 hours daily, depending on their lifestyle.
- Senior Dogs: Older dogs tend to slow down and may sleep closer to 16–18 hours a day as their bodies require more rest and recovery.
3. Breed and Size Matter
Larger breeds, such as Great Danes or Saint Bernards, tend to sleep more than smaller breeds. This is due to their slower metabolism and higher physical demands. Working breeds, such as Border Collies or Belgian Malinois, may sleep less if they have a job or regular stimulation.
4. Activity Level and Mental Stimulation
Dogs that are more physically active or mentally engaged during the day may sleep more soundly at night and take fewer daytime naps. On the flip side, dogs left alone or without enough stimulation may sleep out of boredom. This doesn’t always mean they’re tired, it’s simply something to do when there’s nothing else going on.
5. Health and Nutrition
Health conditions, medications, and diet can also affect a dog’s sleeping patterns. Dogs who are unwell or in pain may sleep more. If you notice sudden changes in your dog’s sleep habits, like excessive lethargy, difficulty waking, or restlessness at night, it’s best to consult your vet.
6. The Comfort Factor
Dogs are opportunistic sleepers. If your pup has a cosy bed, a quiet home, and no reason to stay alert, they’ll nap whenever they feel like it. This behaviour is rooted in their wild ancestors, who conserved energy between hunts or guard duties. Your domesticated pup may not need to hunt anymore, but the instinct to rest remains strong.

Final Thoughts: Let Sleeping Dogs Lie
In most cases, a dog’s sleeping habits are just part of being a dog. As long as your pup is eating well, staying active when awake, and showing no signs of illness, there’s no need to worry about those long naps.
So the next time you see your dog curled up in a sunny spot or snoring softly on the couch, remember, they’re just doing what dogs do best: living life one nap at a time.
