How Many Hours Does A Dog Sleep A Day?

Dogs are known for their love of sleep, but just how many hours does a dog sleep in a day? Much like humans, a dog's sleep needs vary based on age, breed, activity level, and overall health. Dogs generally sleep anywhere from 12 to 14 hours a day, though puppies, senior dogs, and certain breeds may sleep even more.

Just like us, by understanding your dog's sleep patterns, it can help you determine what is normal and when changes in sleep habits might indicate an underlying issue.

How Much Sleep Do Dogs Really Need?

Adult dogs generally sleep between 12 to 14 hours per day. However, this amount can fluctuate depending on a dog’s lifestyle. More active dogs or working breeds tend to sleep slightly less, whereas dogs that are left alone for long periods or have a more sedentary lifestyle may sleep more. Large breeds, such as Mastiffs, Great Danes, and Saint Bernards are known to be heavy sleepers and can snooze for up to 18 hours a day.

Puppies, on the other hand, need significantly more rest. They can sleep anywhere from 18 to 20 hours a day as their bodies and brains are still developing. Much like human babies, puppies wake up in short bursts, eat, play, and then quickly drift back to sleep. Similarly, senior dogs often require more sleep than middle-aged dogs, as their bodies tire more easily.

What If Your Dog Sleeps Too Much?

While dogs are naturally inclined to sleep a lot, excessive sleeping could be a sign of an underlying problem. If your dog suddenly starts sleeping more than usual and seems lethargic even when awake, it may indicate a health issue such as hypothyroidism, diabetes, or even depression. Changes in sleep patterns accompanied by other symptoms like loss of appetite, difficulty moving, or reduced interest in activities should be evaluated by a veterinarian.

Environmental factors can also play a role. Cold weather, boredom, or lack of stimulation may cause a dog to sleep more than usual. By ensuring that your dog exercises regularly, gets plenty of mental stimulation, and social interaction, it can help regulate their sleep cycle.

What If Your Dog Sleeps Too Little?

A dog that is not getting enough sleep may exhibit signs of restlessness, irritability, and even behavioral changes. Just like humans, dogs can become cranky or more reactive when sleep-deprived. Causes of insufficient sleep include anxiety, discomfort from an injury or illness, noisy environments, or an inconsistent sleep routine. Dogs that experience frequent disturbances at night—such as loud noises, bright lights, or interruptions from other pets—may struggle to get the deep rest they need.

If your dog is struggling to sleep, consider creating a quiet, comfortable space for them. If you can provide a cozy bed in a low-traffic area, maintain a consistent bedtime routine, and make sure they get enough exercise during the day, it can help improve their sleep quality.

What Happens When a Dog Is in Deep Sleep?

Dogs, like humans, experience different sleep stages, including light sleep, deep sleep, and REM (rapid eye movement) sleep. It is during REM sleep that dogs enter their deepest sleep state, which is when they tend to twitch, paddle their legs, or even vocalize. This is completely normal and is thought to be a sign that they are dreaming.

Watching a dog twitch in their sleep can sometimes be concerning for pet owners, but it is usually nothing to worry about. However, if your dog appears to be in distress, has excessive or violent movements, or seems disoriented when they wake up, it may be worth checking with your vet to rule out any neurological issues.

If your dog seems to be disturbed during his or her sleep, he could be having a nightmare.

Do Dogs Sleep As Much As Cats?

While dogs sleep a lot, cats are known for being even bigger sleepers. On average, cats sleep between 12 to 16 hours per day, with some sleeping up to 20 hours, especially kittens and senior cats.

Unlike dogs, who typically have a more consolidated sleep schedule with longer stretches of rest, cats sleep in shorter bursts throughout the day and night. This is due to their natural hunting instincts, which require periods of alertness even during rest. If you think your dog sleeps a lot, just remember that cats tend to take the crown for the ultimate nappers!

How to Make Sure That Your Dog Gets Quality Sleep

To help your dog get the best sleep possible, make sure they have a comfortable sleeping environment. Soft bedding, a quiet location, and a stable routine all contribute to a better night’s rest. Regular exercise is also essential—dogs that receive plenty of physical and mental stimulation throughout the day tend to sleep more soundly at night.

Additionally, diet plays a role in sleep quality. Feeding your dog a balanced diet with proper nutrients can support their overall health and energy levels, preventing them from feeling either too lethargic or overly restless. If your dog is prone to anxiety or has trouble settling down, calming supplements, interactive toys, or gentle nighttime routines can help them relax before bed.

While it might be hard to monitor your dog’s sleeping patterns, just know that 12 to 14 hours a day is the average and if you notice any changes, it might be time to see your vet.
