Why Do Dogs Sleep So Much? Understanding Canine Sleep Habits

Why Do Dogs Sleep So Much?

It’s common for dog owners to wonder, sometimes in disbelief, about their dog’s prodigious ability to snooze through the day. Whether your dog seems blissfully napping on the couch, stretched out in a patch of afternoon sun, or dozing lightly at your feet, canine sleep habits often spark curiosity. Understanding why dogs sleep so much is crucial for every responsible pet owner—both for peace of mind and for your dog’s well-being.

Dogs’ Sleep Patterns Are Different

The sleep cycles of dogs share some similarities with humans, but several unique aspects set them apart. Canine sleep begins with a brief period of drowsiness and transitions through the slow-wave phase, during which their breathing slows, heart rate decreases, and blood pressure drops. About ten minutes after dozing off, dogs reach rapid eye movement (REM) sleep—the dream stage. During REM, you might notice your dog’s paws twitching or their eyes darting under their lids, occasionally accompanied by soft barks or whimpers, suggesting they’re dreaming.

Unlike humans, dogs only spend roughly 10% of their sleep in REM compared to about 25% for people. This difference is because dogs’ sleep schedules are far more fragmented and opportunistic. Rather than sleeping primarily at night, dogs tend to nap throughout the day, often waking quickly and being able to become alert instantly if needed. This “polyphasic” sleep pattern is a survival trait, allowing dogs to rest whenever they can while remaining ready for action.

• Dogs average about 50% of each day asleep
• About 30% is spent awake, resting
• Only 20% of a dog’s day is spent being highly active

Because dogs do not get as much REM sleep at a time, they require more total sleep to compensate. Factors such as age, health, personality, and especially breed contribute significantly to the amount of sleep a dog needs.

Age, Health, and Individual Differences

Just as with people, every dog is an individual. While some are perpetual bundles of energy, others are content to lounge and nap. Dr. LaRocco-Skeehan, a canine behavior expert, emphasizes: “You can’t put all dogs into one bucket — a lot depends on their age, their health, and just who they are.” For some dogs, extra sleep is a reflection of personality or a way to stave off boredom. Be aware, though: sudden changes in sleep patterns can indicate medical problems and warrant a veterinary check-up.

How Breed Influences Sleep Needs

One of the most significant factors influencing how much your dog sleeps is breed. Working dogs—such as herding breeds, service dogs, and those historically bred for guarding, hunting, or pulling sleds—often adapt their sleep based on activity demands. During busy periods, these dogs stay alert for longer stretches because they’re performing their jobs. Conversely, more sedentary breeds, or “retired” working dogs, may have fewer energy-intensive tasks and spend more time relaxing and napping throughout the day.

• Working breeds (e.g., Border Collies, Huskies) require more mental and physical stimulation and may sleep less when active tasks are available.
• Companion breeds or those bred for lower energy workloads, like Bulldogs or Basset Hounds, tend to be natural couch potatoes and may sleep more.
• Most modern pet dogs are resilient; if their routines change—such as when boarded in a kennel or taken on vacation—they typically adjust their sleep schedule quickly.

It’s important to plan quality play and exercise time for working breeds to help them rest more deeply and maintain a healthy balance between awake, active, and sleeping hours.

Puppy Sleep: Building Brains and Bodies

If you have a puppy, you might notice the incredible amount of sleep they need—often 18 to 20 hours a day. This extensive sleep fuels tremendous physical growth and is essential for development of the nervous system, muscle repair, immune function, and learning.

• Puppies experience more REM, which helps their brains process new experiences and environmental stimuli.
• Lack of adequate sleep in puppies can lead to irritability, reduced learning, and even health issues.
• A predictable routine—pairing sleep with meals and play—helps puppies adjust and feel safe.

Senior Dogs: The Return to Longer Naps

With advancing age, dogs often revert to patterns seen in puppyhood—long periods of rest, more naps, and less overall activity. Senior dogs (typically 7 years and older for small dogs, 6 years or younger for very large dogs) commonly need 12 to 15 hours of sleep every day.

• Geriatric dogs have naturally lower energy and tire more quickly.
• Medical issues—like arthritis or heart disease—can contribute to changes in sleep duration and quality.
• If a senior dog suddenly begins to sleep much more or less, or becomes restless at night, consult your veterinarian as this can indicate underlying health concerns.

Routine check-ups are vital for senior dogs. Always let your vet know about changes in sleep patterns, as addressing issues early can improve a dog’s comfort and quality of life.

Sleep Positions: What They Reveal About Your Dog

Dogs sleep in a variety of positions, and these often reflect both comfort and their sense of security in the environment. Here’s what some common sleep positions mean:

• On the Back: Dogs who sleep on their backs with paws up are often completely relaxed and trying to cool down. Unlike humans who sweat over the entire body, dogs primarily sweat through their paw pads, and exposing their less furred belly helps release excess body heat. This is typically a sign your dog feels safe and content in their surroundings.
• Curling Up: Many dogs curl tightly with nose to tail, especially in colder temperatures. This classic position conserves body heat and offers a sense of security—a common instinct for dogs with guarding or herding ancestry.
• Side Sleeping: Sprawled on one side, your dog is likely in deep sleep and feels comfortable and at ease in your home environment.
• Sphinx or “Superman”: Lying on their stomach with legs outstretched, dogs can quickly jump to their feet if needed—this position is most common in younger or active dogs during light naps.

Certain breeds—particularly herding and guardian types—are less likely to sleep on their backs. Their roles require constant vigilance, so they tend to nap lightly and be ready to respond at a moment’s notice. Only dogs feeling extra safe (and a bit lazy) adopt belly-up positions.

Should I Let My Dog Sleep With Me?

The topic of whether to invite your dog onto your bed—or even into the bedroom—sparks lively debate among dog owners. From a behavioral or health perspective, sleeping in your bed is not harmful for your dog, and may even provide comfort and enhance your bond. For many owners and dogs, sharing sleep spaces deepens companionship and routine.

If you prefer to keep your sleeping space dog-free—for reasons of allergies, personal preference, or because your dog disrupts your rest—ensure your dog has a comfortable, quiet place of their own to enjoy their many hours of sleep.

Is Too Much Sleep Ever a Cause for Concern?

While sleeping a lot is normal for dogs, there are certain signs that warrant concern. Sudden, dramatic increases or decreases in sleep, changes in waking behavior, or new symptoms—such as confusion, incontinence, or difficulty getting up—should prompt a veterinary visit. Conditions including arthritis, heart disease, diabetes, hypothyroidism, and cognitive dysfunction can cause noticeable shifts in sleep patterns, particularly in older dogs.

• Monitor your dog’s typical sleeping pattern and be alert to significant changes.
• Track additional symptoms like excessive thirst, changes in appetite, new anxieties, or limpness.
• Consult your vet if you notice restless sleep, frequent waking, or any signs of pain overnight.

Ultimately, knowing your dog’s unique habits—and being in tune with what’s “normal” for them—helps you quickly detect changes that could signal health issues.
