Let's face it, we might never find our dogs with bags under their eyes, but dogs, just like us, need their daily dose of beauty sleep. 

How many hours do dogs sleep in 24 hours on average? There's ultimately no real standard time frame, as each dog is an individual. 

Puppies, adult dogs, older dogs and different breeds of dogs may have different levels of energy and they may have different needs when it comes to how many hours of sleep they get.

 However, we can make some average assumptions by adding up those shorter daily naps with those more lengthy night-time snoozes.

Breed Matters For a Good Part.....

When it comes to how much dogs sleep, breed seems to matter.

On one hand, there are dog breeds known for being couch potatoes who may rather snooze on the couch then go on a hike, while on the other hand, there are several dynamite dog breeds who perceive every second spent on the couch as wasted time.

And then you may have some others who have quite flexible schedules. Basically dogs matching their lifestyles with the lifestyles of their owners. 

These pooches are likely to stay awake when their owners are awake and are ready to automatically snooze the moment their owners are reading a book or watching TV.

Want a dog who loves to spend countless hours on the couch snoozing? Look for some of the larger breeds of dogs.

"Some very large breeds of dogs, like Newfoundland's, Saint Bernard's, and mastiffs, often spend a great deal of their lives sleeping---perhaps up to sixteen or even eighteen hours a day," points out Stanley Coren in the book: "What do Dogs Know?"

But Age Matters Too!

Puppies are generally very active pooches, but their batteries tend to discharge quickly. One minute they're up and running, the next they are exhausted as they used up all their energy and need to re-charge. 

Sum all those little naps up though and you'll find that puppies are likely to sleep even up to 18-20 hours a day depending upon their age.

We can't blame them though, pups have a lot of growing to and they need to get all the rest they can get. After all, it is known that growth hormone production increases while the puppy is resting or sleeping. 

Oh, and if you ever notice your puppy getting cranky at times, try to get him to nap; like children, dogs and puppies get grumpy when they are tired too!

"Counting little naps and longer snoozes, most puppies sleep from 18 to 20 hours a day. As your puppy ages, he will sleep less" Dr. Debra Primovic, Pet Place.

Older dogs are on the calmer side of the spectrum, however, some are prone to develop sleep disruptions as they age either due to weak bladders or the onset of the doggy version of Canine Alzheimer's disease, which can dogs to pace, whine and feel confused at night. 

Fortunately, when caught early, this progression of cognitive decline can be slowed down with a script from the vet. 

Adolescent dogs and middle-aged ones are generally quite active and are more likely to look for something to do rather then snooze.

What's a Snipey Muzzle in Dogs?

A snipey muzzle in dogs is something to be aware of, especially if you are planning to breed dogs or enter the show ring business. Even if you plan to use your dog as a hunting partner, you should be aware of snipey muzzles and how they may impact your dog's ability to perform the tasks he was bred for.

Indeed, if you ever bothered to notice, they are likely to frequently awaken for the slightest noises. 

If your household is quite busy, buzzing with activity, such as with kids running around and playing most of the day or nocturnal critters in the yard at night, most likely Rover has a hard time relaxing and catching some zzzs.

This is further proven by studies. For example, according to a study, dogs who slept indoors were reported to spend 80 percent of the night in behaviorally defined sleep, whereas this ratio went down to 70 percent for dogs sleeping outdoors in a yard, and even 60 percent for dogs sleeping outdoors in a non-fenced area. 

Martina Scholz and Clarissa von Reinhardt, in the book: "Stress in Dogs," claim that ideally dogs should rest and sleep seventeen or more hours per day, something that can be quite a challenge in dogs living in busy households.

Make sure he has a quiet spot to retreat to when needed. If your dog is kept outside in the yard nearby a busy street, he also may have a hard time sleeping.

Dogs living in quiet quarters may be more likely to sleep. Generally though, bored, lonely dogs tend to fall in two categories: dog who fall asleep and patiently wait for their owners to come home, and creative dogs who craft their own entertainment venues by doing some landscaping in the yard, going on watch dog duty or remodeling the house chewing through carpets, drywall and upholstery.

Regardless, it appears that the general consensus is that the average middle-aged dog tends to sleep between 12 and 16 hours a day in a 24-hour cycle

Most likely, 8 hours are spent sleeping at night when everybody is asleep, and then an extra 4 to 8 hours are spent snoozing during those down times at other times of the day. 

However as mentioned above, this is just a general guideline as they are too many variables!

Did you know? A domestic dog's tendency to stay awake during the day has been hypothesized to reflect an adaptation to living with humans. This is because of evidence showing how most other wild canines such as red and artic foxes, as well as arctic and grey wolves are nocturnal, crepuscular animals, with diurnal activity being a rare observation. 

What if My Dogs Sleeps Less or More?

Generally, if your dog is acting happy and healthy, sleeping a bit more or a bit less than the average sleeping time for a dog of his age and breed, shouldn't be a concern.

 However, it's best to see the vet if something doesn't seem right and your dog is sleeping much more or much less than he usually does.

 For example, a dog who is sleeping a lot more than usual may be suffering from a health problem such as an infection, heart problem, diabetes or pain in the joints as seen in elderly dogs, according to VCA Animal Hospitals.

On the other hand, sleeping less can be a sign of problems too. Your dog may be too hot or too cold, anxious, or he may have strong pain in the neck, back or abdomen which may require an emergency visit to the vet for pain relief.

Other conditions that may cause restlessness include dogs taking stimulating medications, canine Alzheimer's', allergies that cause persistent licking, or metabolic conditions such Cushing's disease, explains Larry Lachman animal behavior consultant and author of "Dogs on the Couch."

Did you know? A study conducted on pointer dogs sleeping over a 24 hour period revealed that dogs spend about 44 percent of their time in an alert wakeful state, 21 percent in a drowsy state, 23 percent is spent in slow-wave sleep and 12 percent in REM sleep.
