If you've noticed your dog spending more time snoozing during the warmer months, you're not imagining it. Many dogs naturally sleep more during summer, especially when temperatures rise. Just like us, dogs adjust their daily routine to cope with the heat, often choosing to rest instead of being active during the hottest parts of the day.
While extra naps are usually nothing to worry about, it's important to understand what's normal, how hot weather affects your dog's behaviour, and when increased sleeping could signal an underlying health issue.
Do Dogs Naturally Sleep More in Summer?
The short answer is yes... many dogs do.
Dogs don't sweat like humans. Instead, they regulate their body temperature mainly through panting and releasing small amounts of heat through their paw pads. Because cooling themselves takes effort, many dogs conserve energy by resting more when the weather is hot.
You'll often notice your dog:
- Taking longer daytime naps
- Sleeping in cooler rooms or shaded areas
- Being less interested in walks during midday
- Becoming more active in the early morning or evening
- Moving around less than usual
This is a completely normal response to higher temperatures
Why Hot Weather Makes Dogs Sleep More
1. Conserving Energy
When temperatures rise, physical activity requires much more effort. Sleeping allows dogs to reduce their energy expenditure while preventing overheating.
This behaviour is especially common during heatwaves.
2. Avoiding Overheating
Dogs instinctively seek out cool places to rest. You'll often find them stretched out on kitchen tiles, hardwood floors or shaded patios because these surfaces help draw heat away from their bodies.
A cool sleeping environment can make a significant difference to their comfort.
3. Different Walking Times
Many owners naturally avoid walking during the hottest hours of the day. With fewer daytime adventures, dogs often spend more time sleeping until it's cool enough to head outside.
4. Breed Differences
Some breeds are far more affected by warm weather than others.
Dogs with thick double coats include:
- Golden Retrievers
- Labrador Retrievers
- Border Collies
- German Shepherds
- Newfoundlands
Flat-faced (brachycephalic) breeds are also more susceptible to heat because they struggle to cool themselves efficiently:
- Bulldogs
- Pugs
- French Bulldogs
- Boston Terriers
- Shih Tzus
These breeds may sleep significantly more during warm weather.
Puppies and Senior Dogs
Puppies
Young puppies already sleep between 18-20 hours per day, so summer heat may encourage even longer naps as they continue to grow.
Older Dogs
Senior dogs often have reduced mobility and may find hot weather particularly tiring. Arthritis can also become more uncomfortable during changing temperatures, making a supportive bed even more important.
Is Too Much Sleeping Ever a Concern?
Although extra sleep is normal during summer, it's important to know the difference between healthy rest and lethargy.
Contact your vet if your dog is sleeping significantly more and shows any of these signs:
- Refusing food
- Vomiting or diarrhoea
- Difficulty breathing
- Excessive panting that doesn't settle
- Pale or bright red gums
- Weakness or collapse
- Confusion or disorientation
- Reluctance to drink water
These could indicate heat exhaustion or another medical condition requiring immediate attention.
How to Help Your Dog Sleep Comfortably During Summer
Keep Their Bed Cool
Choosing the right sleeping area makes a huge difference.
Move your dog's bed to:
- A shaded room
- Away from direct sunlight
- Near good airflow
- Cooler flooring if possible
If your dog prefers sleeping downstairs during summer, it's simply because those areas often stay cooler.
Choose Breathable Bedding
Beds that trap heat can become uncomfortable during warmer months.
Look for beds with:
- Breathable fabrics
- Removable washable covers
- Thick supportive filling that doesn't flatten
- Moisture-resistant materials
- Plenty of space for your dog to stretch out
Dogs often lie stretched out rather than curled up in summer to help release body heat.
Encourage Hydration
Always provide fresh, cool water throughout the day.
You can also:
- Add ice cubes to water bowls
- Offer frozen dog treats
- Feed water-rich snacks like cucumber or watermelon (in moderation and only if safe for dogs)
Exercise During Cooler Hours
Aim for walks:
- Early morning
- Late evening
Avoid hot pavements, which can burn paw pads and increase the risk of overheating.
Keep Their Sleeping Area Quiet
Just like humans, dogs sleep better when they're undisturbed.
A calm, quiet environment helps them recover from the heat and get quality rest.
Can the Right Dog Bed Help During Summer?
Absolutely.
A supportive dog bed isn't just for winter comfort it plays an important role all year round.
A quality dog bed provides:
- Better airflow around your dog
- Pressure relief for joints
- A comfortable place to rest after exercise
- Insulation from hot patios or rough outdoor surfaces
- Consistent support during longer summer naps
Beds with removable, washable covers are especially useful during warmer months when dogs naturally shed more and may bring in dirt from outdoor adventures.
Summer Sleep Is Perfectly Normal
Most dogs naturally sleep more during summer because they're adapting to warmer temperatures. As long as they're eating, drinking, enjoying gentle exercise and behaving normally when awake, extra naps are usually a healthy way of conserving energy.
Providing plenty of fresh water, avoiding midday heat, and giving your dog a cool, supportive place to sleep can help them stay comfortable throughout the season.
At Four Bare Paws, we believe every nap should be as comfortable as possible. Whether your dog is recovering after an early morning walk or simply escaping the afternoon heat, a supportive, high-quality bed helps them rest, recharge and wake up ready for their next adventure.
Frequently Asked Questions
Is it normal for dogs to sleep all day in summer?
Many dogs sleep more during hot weather to conserve energy and avoid overheating. As long as they're otherwise healthy, eating, drinking and responsive, this is usually perfectly normal.
How many hours do dogs sleep in summer?
Adult dogs typically sleep 12-14 hours per day, although many may sleep a little longer during periods of hot weather.
Why is my dog less active in hot weather?
High temperatures make physical activity more demanding. Dogs naturally reduce their activity levels to help regulate their body temperature and prevent overheating.
Should I let my dog sleep more in summer?
Yes. Allow your dog to rest when they need to, while ensuring they have access to water, shade and a cool place to sleep. Schedule exercise during the cooler parts of the day.
When should I worry about my dog sleeping too much?
Seek veterinary advice if increased sleeping is accompanied by symptoms such as loss of appetite, vomiting, breathing difficulties, collapse, weakness, confusion or signs of heatstroke.
