Sleep & Why it’s so important!
Sleep is one of the most important — and most overlooked — components of a dog’s physical and behavioural wellbeing. Just like humans, dogs rely on quality rest to regulate their emotions, process learning, and maintain optimal health. Yet many behaviour issues seen in training clients stem from one simple cause: a dog who isn’t getting enough sleep.
In this blog post, we’ll explore how much sleep dogs need at every life stage, why sleep patterns may change, and the risks associated with chronic sleep deprivation.
How Much Sleep Do Dogs Need?
Puppies (0–6 months): 18–20+ hours per day
Puppies grow at a remarkable rate, and their brains are constantly forming new connections. They need extensive sleep to support:
• Physical development
• Learning and memory
• Emotional regulation
It’s normal for puppies to be awake only a few hours at a time before needing another nap.
Adolescents (6–18 months): 14–18 hours per day
Young dogs are energetic and curious, but their brains are still maturing. Adequate sleep helps them:
• Manage frustration
• Learn new behaviours
• Stabilise their emotions
Lack of sleep at this stage often shows up as overstimulation or unruly behaviour.
Adult dogs (1–7 years): 12–14 hours per day
Most adult dogs require significantly more sleep than people expect. Factors influencing adult sleep duration include:
• Breed (working and giant breeds often need more)
• Activity level
• Household environment
Offering predictable rest opportunities throughout the day is essential.
Senior dogs (7+ years): 14–18 hours per day
As dogs age, their bodies and minds tire more easily. Increased sleep supports:
• Joint recovery
• Cognitive health
• Energy for daily activities
Older dogs may nap more frequently and sleep more deeply.
Why Your Dog’s Sleep Might Change
Sleep patterns aren’t fixed. They can shift for several reasons:
1. Increased Activity or Stimulation
A busy day, new experiences, or intensive training can lead to extra sleep as your dog’s brain processes the information.
2. Stress or Anxiety
Stress can cause either difficulty settling or increased fatigue. Changes like moving house, household conflict, or schedule disruptions can all alter sleep.
3. Health or Pain Issues
Pain, discomfort, digestive problems, or underlying medical conditions may interrupt sleep, cause restlessness, or make a dog sleep more than usual.
4. Environmental Disturbances
Noise, visitors, children, pets, or lack of a safe resting space can prevent dogs from properly switching off.
5. Routine Disruptions
Changes in feeding times, exercise schedules, or owner presence can affect sleep–wake cycles.
The Problem with Not Getting Enough Sleep
Chronic sleep deprivation is a major contributor to behavioural difficulties in dogs. Some of the key risks include:
1. Increased Reactivity
Tired dogs have less emotional resilience. This can lead to:
• Barking or growling
• Sensitivity to sounds or movement
• Reduced tolerance for handling or interaction
2. Poor Learning and Training Performance
Sleep is essential for memory consolidation. Dogs who are overtired:
• Struggle to focus
• Retain less information
• Become easily frustrated
3. Hyperactivity and Overarousal
Many signs of “excess energy” or “naughtiness” are actually symptoms of fatigue. The dog becomes overstimulated because they can’t regulate their behaviour.
4. Decreased tolerance
A tired dog may have a shorter fuse and react defensively to things they would normally tolerate.
5. Compromised Immune System
Just like humans, lack of sleep affects physical health:
• Weakened immunity
• Slower recovery
• Higher stress hormones
6. Reduced Quality of Life
Dogs who can’t rest properly may appear restless, irritable, clingy, or constantly “on alert.”
Helping Your Dog Get Better Sleep
• Provide multiple quiet, comfortable rest areas.
• Avoid waking your dog unnecessarily.
• Use crates, pens, or baby gates if your dog struggles to switch off (only if your dog is crate trained first!).
• Incorporate structured calm time into daily routines.
• Reduce overstimulation—especially for puppies and adolescents.
• Seek veterinary advice if you suspect pain or sleep disturbances.
Final Thoughts
Sleep is not a luxury for dogs — it’s a biological necessity. Ensuring your dog gets the right amount of rest at their life stage can reduce behavioural issues, improve training progress, and contribute to a happier, calmer companion.
