Good question: how many hours a day do dogs sleep? Some people think their dogs sleep all day, and others think they are eternally awake! Much depends on the breed, so how much do they need? How much sleep does a dog need in order to be alert and active during their non-sleeping hours?
Dogs doze a lot for relatively short periods, unlike human beings who tend to take their sleep in one roughly 8-hour period - usually at night. While humans sleep for about 1/3 of their day, dogs tend to sleep a total of 50% - 60% of their day, some even more. Larger breeds, such as St. Bernards, Newfoundlands, mastiffs, Irish wolfhounds, etc, sleep for longer than smaller breeds, this generally being in the form of naps - the larger the breed the more naps they tend to take.
However, dogs need more sleeping time than humans in order to get the right amount of restorative REM sleep. Because of the preponderance of naps, they tend to take, REM sleep (the most restorative kind of sleep) takes up only around 10% of their sleeping time. So they need more sleep to feel restored and ready to chase cats, sticks, and balls again.

Dogs' Sleeping Habits
Dogs do not sleep according to a schedule as humans do, but whenever they feel like it. They are active around 20% of a day, and spend around 30% awake, lying or padding around. However, unlike humans who take a while to wake up properly, they can be instantly awake, alert and ready for action if the doorbell rings or mail comes through the door. They can even sense the mailman or woman approaching their house, and are ready and waiting for their opportunity to remove a finger or two!
Working dogs tend to sleep less than pets. Dogs that work on farms, or police or army dogs, have less time to lie around, and they tend to sleep less than dogs kept as pets. While it makes sense to believe that working dogs should sleep more than dogs kept as pets, this is not the case. They tend to sleep less than dogs that are kept in the house all day with nothing to do but sleep or get into mischief!
This is because dogs that work have to be physically fir and also mentally alert. Police and army dogs are often called into action at a moment's notice with one command. Such dogs must be attentive and ready for action when awake, and dogs trained to do so will be less likely to sleep as much as house dogs. If the dog is given a job that involves it keeping its attention on what it is doing, it is less likely to take sleep, or even take a nap. Eventually, when time is available, the working dog will nap or even sleep for a protracted period while it catches up with the sleep it has lost while on duty.
Signs That Your Dog Needs Attention
You should be aware of your dog's regular sleeping habits to the extent that you will notice when these suddenly change. If your dog is normally sleeping or napping most of the time, then suddenly starts becoming very active, then it's wise to contact your vet for a quick checkout (your dog, not you.)
Similarly, if you have a very active dog that suddenly falls asleep all the time, then it may need veterinary attention. Dogs that suddenly change their sleeping habits from less to more, or vice versa, may have thyroid issues, breathing or heart problems, or might simply be on the wrong diet for its breed, size, and age. It's always best to get a professional opinion in such cases.
Canine Sleeping Cycles and Regular Environment
A dog has sleeping cycles just as a human does. As they fall asleep, they begin in a slow wave and as this progresses their breathing and heart rate become slower and their blood pressure drops. After around 10 minutes, they enter REM sleep, again just as humans do. You should be able to see their eyes moving under their eyelids. Dogs react to dreams just as humans do: they may whimper, twitch and occasionally even bark. This may wake them up, but they usually stay asleep. Humans remain in REM sleep for around a quarter of their sleeping time, REM phase sleeping by dogs is only around a tenth of their sleeping time.

Conclusion: How Many Hours a Day Do Dogs Sleep?
The simple answer is 12 - 14 hours a day. However, unlike humans, they spread these hours out over the day. Dogs tend to take naps rather than protracted periods of sleep as humans do. Once you are aware of your dog's normal sleeping habits, it should be fairly easy for you to notice when this changes. This could indicate that there is something wrong with your dog. You should then contact a vet.
