The Science of Canine Sleep

How Dogs Sleep: Cycles and Patterns

Dog sleep patterns involve different stages of sleep, though their sleep cycles differ significantly from humans. While dogs fulfill all behavioral and polygraphic criteria of sleep, they have distinct sleep characteristics including sleep homeostasis, diurnal activity patterns, circadian rhythms, and ultradian sleep cycles that are socio-ecologically influenced.

The typical dog spends approximately 50% of their day sleeping, 30% awake but relaxing, and just 20% being active. This distribution of dog sleep patterns makes sense from an evolutionary perspective, as conserving energy between hunting or patrolling periods would be advantageous.

Dogs have two main sleep phases similar to humans:

1. Non-REM (slow wave) Sleep: This initial phase is characterized by slower brain waves. It’s a lighter sleep where the body heals and restores itself.
2. REM (Rapid Eye Movement) Sleep: This is the deep sleep phase where dreaming occurs. Interestingly, dogs only spend about 10% of their sleep time in REM compared to humans’ 25%. This is due to their irregular sleep patterns—dogs tend to doze off whenever they want, often out of boredom, and wake up quickly to jump to alertness.

A groundbreaking study from North Carolina State University established important baselines for normal dog sleep patterns. The research revealed that most healthy adult dogs have two main activity peaks during the day: the first from 8 am to 10 am, followed by a midday lull, and then a longer active period from approximately 5 pm to 11 pm. All dogs in the study were more active during weekends than weekdays.

Sleep Patterns by Breed and Size

While all dogs share similar sleep cycle structures, significant differences exist between breeds, sizes, and ages:

As a general rule, larger breeds typically spend more time sleeping than smaller breeds. This difference in dog sleep patterns is partly due to energy expenditure—larger bodies require more energy to function and thus need more recovery time.

Breed-specific differences in dog sleep patterns can be substantial:

• Working breeds like Border Collies and Australian Shepherds tend to have higher energy levels and may require less sleep than breeds bred for companionship.
• Bulldogs, Mastiffs, and other large or brachycephalic (flat-faced) breeds often sleep more, sometimes up to 18 hours daily.

Research has also found that sex and weight influence dog sleep patterns and activity cycles. Lighter dogs showed more activity in a short period just after midnight, while female dogs displayed increased activity during evening peak times compared to males. Even among healthy adult dogs, age played a role—older dogs exhibited less activity during peak activity times.

These differences highlight the importance of understanding your specific dog’s normal sleep patterns rather than applying a one-size-fits-all approach.

The Impact of Age on Sleep

Sleep requirements change dramatically throughout a dog’s life:

Puppies: Young puppies need significantly more sleep than adult dogs. They experience greater sleep duration during the day and in total over a 24-hour period, though they typically sleep for shorter periods at night compared to adult dogs. This increased sleep requirement supports their rapid growth and development.

Adult Dogs: A healthy adult dog typically needs 12-14 hours of sleep per day, though this varies by breed, size, and activity level.

Senior Dogs: Older dogs often require more sleep as they tire more easily. However, they may struggle with quality sleep due to age-related conditions like arthritis, cognitive dysfunction, or other health issues.

Senior Dogs and Cognitive Dysfunction Syndrome

Cognitive Dysfunction Syndrome (CDS) or “doggy dementia” significantly impacts sleep in aging dogs. One of the earliest and most noticeable symptoms is disruption to normal sleep-wake cycles, often manifesting as “sundowning”—increased confusion, restlessness, and anxiety as evening approaches. Dogs with CDS may:

• Pace, whine, or vocalize during nighttime hours
• Appear disoriented upon waking
• Sleep more during the day and less at night
• Show increased irritability due to sleep deprivation

Early intervention is crucial. If your senior dog shows these symptoms, consult your veterinarian, as treatments including specialized diets, supplements like S-adenosylmethionine (SAMe), and environmental modifications can help manage the condition and improve sleep quality.

Understanding these age-related changes helps owners set appropriate expectations and identify when sleep patterns deviate from normal in ways that might indicate health concerns.

Common Sleep Issues in Dogs

Recognizing Sleep Disorders

Just like humans, dogs can suffer from various sleep disorders that affect their health and quality of life. Being able to recognize the signs of disrupted dog sleep patterns is crucial for early intervention.

Sleep disorders are relatively uncommon in dogs overall, but when they occur, they can significantly impact a dog’s wellbeing. The four most common sleep disorders that disrupt normal dog sleep patterns include insomnia, sleep apnea, narcolepsy, and REM sleep behavior disorder.

Signs to watch for:

1. Insomnia: Dogs with insomnia will often pace, whine, bark, or act confused at night. They may try to wake their human family members and typically appear much more tired during the daytime.
2. Sleep Apnea: A common sign of sleep apnea is loud snoring throughout the night. Dogs with this condition may also appear tired during the day and may jolt awake and then fall back asleep. This disorder is more common in obese dogs and brachycephalic breeds like Boston Terriers, Pugs, and English Bulldogs due to their anatomical airway structure.
   

   IMPORTANT: Sleep apnea vs. respiratory conditions
   Some respiratory conditions can mimic sleep apnea symptoms. If your dog stops breathing momentarily during sleep and has noisy breathing while awake, conditions like laryngeal paralysis or tracheal collapse might be the culprit rather than true sleep apnea. These require different treatments, so proper diagnosis is crucial.

3. Narcolepsy: Signs include fragmented (broken) sleep, excessive daytime sleepiness, and sudden physical falls (cataplexy) during play or when excited. It’s particularly frightening for pet owners the first few times they witness a narcoleptic episode.
4. REM Behavior Disorder: Dogs with this condition may exhibit violent limb movements, growling, howling, barking, chewing, and even biting while asleep. Under normal circumstances, a dog’s brain prevents movement during dreaming.

Seizures During Sleep vs. Sleep Disorders

It’s important to distinguish between sleep disorders and seizure activity that occurs during sleep. Unlike the movements seen in REM behavior disorder, seizures typically involve:

• Rigid, stiff body posture
• Paddling motions of all four limbs simultaneously
• Loss of bladder or bowel control
• A “post-ictal” phase of confusion or disorientation after the event

If you suspect your dog is having seizures rather than sleep disturbances, video recording an episode can help your veterinarian make an accurate diagnosis. This distinction is critical, as epilepsy requires specific medical management different from sleep disorder treatments.

Causes of Sleep Problems

Sleep issues in dogs can stem from various sources:

1. Environmental Factors:
   • Uncomfortable sleeping surface
   • Temperature extremes
   • Noise disturbances
   • Changes in routine or environment
2. Medical Conditions: Insomnia in dogs usually has an underlying behavioral or medical cause. Common causes include canine cognitive dysfunction (dementia), anxiety or stress, pain (often from conditions like arthritis), and excessive itchiness from allergies or skin conditions.
3. Breed-Specific Issues: Sleep apnea is more likely to affect obese dogs and dogs with flat faces due to their airway structure. Narcolepsy has been identified as an inherited trait in certain breeds, including Dachshunds, Dobermans, and Labrador Retrievers.
4. Age-Related Changes: Senior dogs often develop sleep disturbances related to cognitive decline, sensory loss, or physical discomfort.
5. Medication Side Effects: Several commonly prescribed medications can disrupt normal sleep patterns in dogs:
   • Corticosteroids like prednisone often cause increased thirst, urination, and restlessness
   • Some antihistamines have a paradoxical effect in dogs, causing hyperactivity instead of drowsiness
   • Certain heart medications may increase urination frequency, leading to nighttime waking

   If your dog’s sleep issues began after starting a new medication, consult with your veterinarian about potential alternatives or timing adjustments.

Understanding the root cause is essential for effective treatment. If you notice any unusual sleep patterns in your dog, documenting these changes and consulting with your veterinarian is the recommended first step.

Improving Your Dog’s Sleep Quality

Creating the Optimal Sleep Environment

The right sleeping environment can dramatically improve your dog’s rest quality:

1. Comfortable Sleeping Surface: Orthopedic beds with memory foam provide superior support for dogs of all ages but are especially beneficial for older dogs or those with joint issues. Quality orthopedic dog beds combine memory foam with features like bolstered sides for additional support and comfort.Top Picks for Orthopedic Dog Beds:

2. Temperature Control: Dogs sleep best in moderate temperatures. Too hot or too cold environments can disrupt sleep. Consider seasonal bedding changes—cooling mats in summer and warmer, insulated beds in winter.
3. Noise Management: Sound therapy using white noise machines can be beneficial for dogs, particularly those with anxiety, restlessness, or noise sensitivity. The steady, soothing noise helps block out disruptive sounds and provides a calming environment that encourages sleep.
4. Consistent Location: The best placement for dog beds is along a wall or in a corner, which helps dogs feel more secure compared to open spaces. Avoid placing beds in high-traffic areas or in the middle of rooms to prevent accidents and disturbances.
5. Light Management: While less sensitive to light than humans, dogs still benefit from darkened sleep environments, especially at night.

Exercise and Activity for Better Sleep

Physical and mental stimulation plays a crucial role in promoting healthy sleep patterns:

1. Physical Exercise: Exercise is a major part of life for dogs, and insufficient physical activity can prevent good sleep. Dogs with insomnia and sleep apnea can benefit from increased daily physical activity, which helps burn off excess energy, relieves anxiety, and maintains a healthy weight.
2. Mental Stimulation: Puzzle toys, training sessions, and interactive games provide mental exercise that can tire a dog out as effectively as physical activity.
3. Timing Matters: Schedule vigorous exercise earlier in the day, allowing time for your dog to wind down before bedtime. A gentle evening walk can help promote relaxation without over-stimulation.
4. Consistent Routine: Dogs thrive on predictability. Maintaining consistent times for activities, meals, and sleep helps regulate their internal clock and promotes better sleep quality.

Behavioral Modifications for Better Sleep

For many dogs, sleep problems stem from anxiety, stress, or insufficient enrichment during the day. These behavioral approaches can make a significant difference:

1. Establish a Bedtime Routine: Create a predictable sequence of events leading up to bedtime, such as a short walk, a quiet play session, and then a specific command that signals it’s time to sleep. Consistency helps dogs understand when it’s time to wind down.
2. Crate Training for Sleep: When done properly, crate training can provide a secure, den-like environment that promotes better sleep. The key steps include:
   • Selecting an appropriately sized crate
   • Making it comfortable with bedding
   • Introducing the crate gradually with positive reinforcement
   • Never using the crate as punishment
   • Covering the crate with a breathable blanket to create darkness
3. Desensitization for Noise Phobias: Dogs with noise sensitivities that disrupt sleep can benefit from gradual desensitization:
   • Play recordings of triggering sounds (thunderstorms, fireworks) at very low volume
   • Reward calm behavior
   • Gradually increase volume over days or weeks
   • Pair with calming activities like massage or puzzle toys
4. Comfort Objects and Calming Signals: Some dogs sleep better with:
   • A t-shirt carrying their owner’s scent
   • A heartbeat simulator toy for puppies
   • A specific “sleep” blanket used only at bedtime

By balancing physical exercise with mental stimulation, maintaining a predictable routine, and implementing these behavioral strategies, you can help ensure your dog is appropriately tired at bedtime but not overstimulated.

Supplements and Aids for Sleep

Several supplements and aids can help improve sleep quality for dogs experiencing difficulties:

1. Calming Supplements: Common supplements used to address sleep issues in dogs include melatonin, valerian, and kava. These can help reduce anxiety and promote relaxation, but should only be used after consultation with a veterinarian.
2. White Noise Machines: White noise machines designed specifically for dogs can provide a range of soothing sounds that help mask disruptive noises like thunderstorms, fireworks, or street sounds. These devices often offer various sound options including white noise, brown noise, nature sounds, and specially composed calming music.
3. Calming Beds: Calming dog beds typically use plush materials and bolstered edges to create a sense of privacy and security, which may help anxious dogs feel more relaxed. These beds mimic the comfort of snuggling against a warm mother and littermates, potentially alleviating stress.
4. Pheromone Products: Synthetic dog-appeasing pheromones, available as diffusers, sprays, or collars, can help create a sense of security and calmness.

Remember that supplements and aids should complement, not replace, proper veterinary care. Always consult with your veterinarian before starting any supplement regimen, especially if your dog has existing health conditions or is taking other medications.

Medical Interventions for Sleep Disorders

When supplements and environmental changes aren’t sufficient, medical interventions may be necessary:

For insomnia, veterinarians may prescribe medications to help with sleep and reduce anxiety. Examples include trazodone, clorazepate, alprazolam, flurazepam, and clonazepam.

For dogs with sleep apnea due to anatomical issues like narrow nostrils or elongated soft palates (common in brachycephalic breeds), corrective surgeries can improve breathing and reduce snoring.

In cases where an underlying condition causes insomnia, treating that condition often resolves the sleep issues. For example, arthritis-related insomnia may improve with proper pain management medications like grapiprant (Galliprant) combined with an orthopedic dog bed.

There is no definitive treatment for dogs with narcolepsy. Management focuses on identifying and minimizing triggers, such as excitement that precedes episodes, and creating a safe environment for when episodes occur.

When sleep disorders significantly impact quality of life, don’t hesitate to seek veterinary assistance. Modern veterinary medicine offers various options to help your dog achieve better rest.
