Dogs require a healthy amount of sleep to maintain their physical health, cognitive function, and emotional well-being. On average, dogs spend about 10-14 hours a day sleeping, which can actually be more than many adult humans, who sleep roughly a third of their lives (Mondino et al., 2021). Unlike humans, dogs naturally sleep multiple times throughout the day and night in shorter periods, a pattern known as polyphasic sleep.
Each sleep cycle typically lasts around 20 minutes and includes different sleep stages that serve unique functions (Toth & Bhargava, 2013). Dogs alternate between wakefulness and two main types of sleep: Non-Rapid Eye Movement (NREM) sleep, which is deeper and restorative, and Rapid Eye Movement (REM) sleep, associated with dreaming and brain activity important for memory consolidation.
The amount of sleep a dog needs depends on various factors, including:
· Age: Puppies and senior dogs sleep much more than adult dogs to support growth and recovery (Mondino et al., 2021).
· Breed and Size: Larger breeds may sleep longer; also, brachycephalic breeds are prone to sleep-disordered breathing, which can fragment sleep, leading to a longer overall sleep requirement due to poorer quality of sleep.
· Activity Level: Active or working dogs tend to need more rest to recover physically and mentally.
Understanding how much sleep your dog needs and recognising normal sleep patterns is vital. Sleep deprivation or disrupted sleep affects dogs similarly to humans—it impairs cognitive and physical performance, weakens immune responses, increases pain sensitivity, and contributes to metabolic and cardiovascular issues (Mondino et al., 2021; Gruen et al., 2019).
If your dog is sleeping significantly more or less than usual, or shows unusual behaviours like sudden sleep attacks, frequent awakenings, or acting out dreams, these could be signs of sleep disorders or other health problems warranting veterinary attention.
In the following sections, we will explore canine sleep, ideal sleep durations by life stage, common sleep disorders in dogs, and practical tips to ensure your dog enjoys healthy, restorative sleep.
Why Is Sleep Important for My Dog’s Health and well-being?
Sleep plays a crucial, active role in maintaining your dog’s overall health—far beyond just resting or “recharging.” Research, including the comprehensive review by Mondino et al. (2021), highlights several key reasons why quality sleep is essential for dogs:
1. Physical Restoration and Immune Support
During the deeper stages of sleep, specifically Non-Rapid Eye Movement (NREM) sleep, your dog’s body repairs tissues and replenishes energy stores. This is especially important after physical activity or for growing puppies whose bodies are developing rapidly. Sleep also
bolsters the immune system, making your dog better able to fend off infections and recover from illness (Mondino et al., 2021).
2. Cognitive Function and Learning
Dogs use sleep to consolidate memories and process experiences—a process known as memory consolidation. The Rapid Eye Movement (REM) sleep phase is especially important for this, as the brain is highly active while muscles remain relaxed. This phase helps dogs learn new commands, process social interactions, and adapt to their environments effectively (Mondino et al., 2021; Toth & Bhargava, 2013). Studies show that sleep helps improve dogs’ learning performance, highlighting its importance in training and behavioural development.
3. Pain Regulation
There is a two-way connection between sleep and pain. In dogs with chronic pain—such as arthritis—pain can disturb sleep, making it fragmented or restless. Conversely, sleep deprivation worsens the perception of pain, creating a challenging cycle. Effective pain management in dogs has been shown to improve sleep quality, reduce daytime sleepiness, and improve behaviour (Gruen et al., 2019; Mondino et al., 2021).
4. Emotional Health and Behaviour
Sleep supports brain areas that regulate emotions and stress. Dogs that don’t get enough sleep or experience sleep disturbances may become more anxious, irritable, or hyperactive. Quality sleep contributes to emotional stability, helping your dog remain calm and well-adjusted (Mondino et al., 2021).
5. Clearance of Neurotoxic Waste
Sleep may aid in clearing waste products from the brain that accumulate during wakefulness, a process important for long-term brain health and preventing cognitive decline. This is believed to protect against neurodegenerative conditions, which is especially relevant for ageing dogs (Mondino et al., 2021).
6. Metabolic and Cardiovascular Health
Just as it can in people, poor sleep can negatively affect your dog’s metabolism and cardiovascular system. Dogs with sleep-disordered breathing, especially in short-nosed breeds, are at higher risk of conditions such as obesity, hypertension, and heart problems (Mondino et al., 2021).
In short, sleep is a cornerstone of your dog’s physical healing, brain function, mood regulation, and overall quality of life. Ensuring your dog gets sufficient restful sleep each day supports their health in multiple vital ways.
What Happens When My Dog Sleeps? What Are the Different Stages of Canine Sleep?
Understanding what happens when your dog sleeps can help you recognise normal behaviour and spot any problems early. Dogs, like humans, don’t just sleep in a single state but cycle
through different stages of sleep and wakefulness, each serving unique functions for their health.
The Three Main Sleep and Wake States in Dogs
1. Wakefulness: This is when your dog is fully awake, alert, and active. Their brain activity shows fast, low-amplitude waves, and muscle tone is high as they move and interact with their environment.
2. Non-Rapid Eye Movement (NREM) Sleep: This is often called “slow-wave” sleep, characterised by synchronised, high-amplitude slow waves in the brain. During NREM sleep, muscle tone decreases, the body relaxes deeply, and tissue repair and energy restoration occur. This stage accounts for the majority of dogs’ sleep time and can be further divided into light and deep sleep.
3. Rapid Eye Movement (REM) Sleep: During REM sleep, the brain shows waves similar to when awake, and most skeletal muscles are temporarily paralysed. This paralysis prevents dogs from acting out their dreams—a protective mechanism. However, small twitches of the eyes, face, paws, and ears are common in this phase.
REM sleep is vital for memory integration, emotional processing, and cognitive rejuvenation (Mondino et al., 2021).
How Dogs Cycle Through These States
Dogs are polyphasic sleepers—they cycle between wakefulness and sleep multiple times each day and night, rather than sleeping in one long block like humans. Each sleep cycle lasts approximately 20 minutes, with roughly two-thirds spent in NREM and one-third in REM. This pattern means dogs take frequent short naps, interspersed with periods of activity.
Polysomnography—a sleep study that records brain waves (EEG), muscle activity (EMG), and eye movements (EOG)—has been used to study canine sleep, confirming many similarities and some differences with human sleep patterns. For example, dogs tend to have shorter sleep cycles and more frequent transitions between sleep and wakefulness.
Why Is This Important for You as a Dog Owner?
Knowing that your dog’s sleep is divided into these stages helps you understand behaviours like twitching during dreams, frequent naps, or brief wakefulness at night—all normal parts of healthy sleep.
If your dog doesn’t show typical signs of these sleep stages, or if you notice excessive restlessness, frequent awakenings, or unusual behaviours during sleep, it could indicate a sleep disorder or discomfort. Consulting your veterinarian with these observations is key to early diagnosis and treatment.
How Much Sleep Do Puppies Need and Why Is It So Important?
Puppies are little powerhouses of energy, but they also need a lot of sleep—much more than adult dogs. On average, a puppy will sleep between 18 and 20 hours a day. This abundant sleep is essential because their bodies and brains are rapidly growing and developing during this critical stage.
Why Puppies Need So Much Sleep
1. Physical Growth and Development: Puppies’ muscles, bones, and organs are still growing. Deep stages of sleep, especially Non-Rapid Eye Movement (NREM) sleep, allow the body to repair tissues and build strength. Without this restorative sleep, a puppy’s development could be impaired or slowed.
2. Brain Development and Learning: Sleep plays a vital role in how puppies process what they learn each day. The brain consolidates memories and skills during REM (Rapid Eye Movement) and NREM sleep stages. This is why sleep is so crucial during the early socialisation and training period; it helps puppies remember commands, social cues, and navigate new environments confidently.
3. Immune System Support: Sleep also boosts the immune system, helping puppies fight off the many new germs they encounter as they explore their world. A well-rested puppy is more likely to stay healthy and bounce back quickly if they do get sick.
What Does This Look Like in Real Life?
Because puppies wake frequently—both naturally and from their energetic bursts—they often sleep in multiple short naps. You might notice your puppy snoozing a lot in between quick episodes of play and exploration. This polyphasic sleep pattern allows them to conserve energy and recover faster.
Tips for Supporting Healthy Puppy Sleep
· Provide a Quiet and Safe Sleep Space: Choose a comfy, cosy area away from noise and distractions, so your puppy feels secure enough to nap peacefully. Puppies are sensitive to their environment, and disturbances can make it harder for them to rest well.
· Establish a Routine: Predictable feeding, play, and nap times help regulate your puppy’s natural sleep-wake cycle. This routine supports better sleep quality and helps reduce anxiety.
· Watch for Signs of Sleep Disruption: If your puppy seems overly irritable, has difficulty settling down, or shows excessive tiredness, it could indicate sleep problems or overstimulation.
· Limit Overexertion: While play is important, too much activity without adequate rest can exhaust your puppy and negatively affect sleep patterns.
Understanding the critical role sleep plays in your puppy’s health lays the foundation for supporting their growth and training effectively. Making sure your puppy gets plenty of quality sleep every day helps them grow into a healthy, happy adult dog.
How Much Sleep Do Senior Dogs Need and What Changes Occur?
As dogs enter their senior years, generally around 7 years of age and older (though this can vary by breed and size), their sleep patterns and needs change significantly. Senior dogs often sleep more than their adult counterparts, averaging 16 to 18 hours of sleep per day. This increased sleep plays an essential role in helping ageing dogs manage physical and cognitive changes that occur with time.
Why Senior Dogs Need More Sleep
1. Reduced Energy and Recovery Needs: Older dogs typically have less stamina and lower activity levels than younger adults. Their bodies require longer and more frequent rest periods to replenish energy.
2. Managing Chronic Pain and Joint Issues: Many senior dogs suffer from ailments such as arthritis or other musculoskeletal conditions that cause discomfort or pain. Pain can interfere with quality sleep, leading to frequent awakenings or restlessness. Conversely, adequate rest can help alleviate some pain symptoms by allowing recovery and reducing inflammation. Special supportive bedding, such as the OrthoLuxe beds from VetRelieve, that redistributes pressure can be highly beneficial for sleep comfort.
3. Cognitive Decline and Sleep Disruption: Senior dogs are at increased risk of developing Canine Cognitive Dysfunction (CCD), a condition similar to dementia in humans. A hallmark symptom of CCD is alteration in the sleep-wake cycle—often presenting as nighttime restlessness and increased daytime napping. This disruption can significantly reduce the quality of life for both dogs and their owners.
4. Changes in Sleep Architecture: Research shows that elderly dogs may experience fragmented sleep, with more frequent shifts between sleep and wakefulness, lighter sleep stages, and less deep restorative sleep. These changes may require tailored management to ensure seniors get sufficient restorative rest.
What Does This Mean for Your Senior Dog’s Sleep?
· Senior dogs typically sleep longer but may have fewer continuous stretches of deep sleep. Instead, they may nap more often throughout the day.
· You may observe increased nighttime pacing, vocalisations, or difficulty settling down—possible signs of cognitive dysfunction or discomfort.
· Sleep disturbances related to pain or cognitive decline are common but may be manageable with veterinary guidance.
Tips for Supporting Healthy Sleep in Senior Dogs
· Provide Comfortable, Pressure-Relieving Bedding: Orthopaedic or specially designed sleep mats—such as VetRelieve’s OrthoLuxe beds and mattresses—can offer crucial joint support and reduce discomfort, promoting longer, more restful sleep.
· Maintain a Consistent Routine and Sleep Environment: Keep feeding, exercise, and quiet time on a predictable schedule to help regulate your dog’s internal clock.
· Pain Management: Work with your veterinarian to manage arthritis or other painful conditions that may prevent restful sleep.
· Monitor Cognitive Health: Be vigilant for signs of cognitive decline, such as confusion or altered sleep patterns, and discuss these with your vet. Early intervention can help improve quality of life.
· Create a Calm, Safe Sleep Space: Make your senior dog’s sleeping area quiet and easily accessible, taking limited mobility or age-related sensory changes into account.
By recognising these natural changes and intervening thoughtfully, you can help your senior dog enjoy their golden years with comfort, improved sleep quality, and better overall well-being.
