A summer walk can begin comfortably and become too demanding before you realize it. Your dog may keep chasing a ball, following you down a sunny path, or running around the garden even when their body is struggling to release heat. Their enthusiasm is not a reliable indicator of how well they are coping.
Unlike humans, dogs rely primarily on panting to cool themselves, with only a limited contribution from sweating through their paw pads. Hot weather, humidity, strenuous activity, and poor ventilation can make temperature regulation more difficult. AKC: How Dogs Stay Cool
The best approach is to prevent overheating before it starts. With the right walking schedule, fresh water, a cool resting area, and an understanding of early warning signs, you can make summer safer without giving up the activities your dog enjoys.

Quick Answer
To keep your dog cool in summer, provide constant access to fresh water and shade, exercise during cooler hours, avoid hot pavement, and never leave your dog in a parked car. Watch for excessive panting, heavy drooling, weakness, or unsteadiness. If heatstroke is suspected, move your dog out of the heat, begin cooling immediately with cool running water, contact an emergency veterinarian, and arrange immediate veterinary care.
Key Takeaways
- Dogs cool themselves mainly through panting, not whole-body sweating.
- Humidity, direct sunlight, exercise, and individual health risks all affect heat tolerance.
- Offer fresh water frequently and carry a portable bowl on outings.
- Avoid hot pavement, even when the air feels relatively comfortable.
- Flat-faced dogs, overweight dogs, seniors, puppies, and dogs with certain medical conditions need additional care.
- Never shave a double-coated dog simply to keep them cool.
- Heatstroke is an emergency. Start safe cooling immediately and contact a veterinarian without delay.
1. Hydration: Your First Line of Defense
Water should be available throughout the day, with extra attention during warm weather and physical activity.
Panting helps dogs release heat through evaporation, but it also contributes to fluid loss. A dog that spends time outdoors needs opportunities to drink, rest, and recover rather than being encouraged to continue exercising.
Your hydration checklist
- Keep fresh drinking water accessible indoors and outdoors.
- Refill and clean water bowls regularly.
- Bring drinking water on walks, hikes, and car trips.
- Offer regular opportunities to drink during activity, rather than waiting until your dog appears tired or thirsty.
- Never force water into a dog that is struggling to breathe, confused, or unable to swallow normally.
Water fountains may encourage some dogs to drink, although many dogs hydrate perfectly well from a clean bowl. What matters most is reliable access to fresh water and a setup your dog consistently uses.
For home hydration, the 3.2L Stainless Steel Pet Water Fountain offers a circulating water supply and a double-filtration system. It is designed for everyday hydration, not as a way to cool a dog experiencing heat stress. You still need to monitor water levels, clean the unit, and provide a backup bowl if the pump stops.
For walks, the Dog & Cat Foldable Silicone Travel Bowl folds flat for carrying and unfolds when your dog needs a drink.
For more on maintaining healthy drinking habits, see The Ultimate Guide to Pet Hydration.
2. Walk at the Right Time and Protect Those Paws
Early morning and later evening are often cooler choices for walks, but the clock alone does not tell you whether conditions are safe. Pavement can retain heat after the sun has begun to set.
The pavement test
The AKC recommends placing your hand on pavement for about ten seconds. If it is too hot to hold comfortably, it may be too hot for your dog's paw pads. AKC: Protecting Dog Paws From Hot Pavement
Treat this as a precaution, not a guarantee. Surface temperature varies with material, sunlight, shade, and recent weather. If the pavement feels very hot, choose grass or a shaded route instead.
Your walking checklist:
- Check the weather, humidity, and pavement before leaving.
- Prefer shaded routes and grassy areas when conditions are warm.
- Keep walks shorter and slower during hot weather.
- Carry water and pause in the shade.
- Stop if your dog begins slowing down, seeking shade, panting unusually hard, or resisting continued movement.
There is no universal temperature at which every dog can safely exercise. A healthy, acclimated dog may cope differently from a flat-faced senior dog with heart or respiratory disease. Make decisions according to the conditions and your individual dog, not a temperature chart alone.
If the weather is very hot or humid, skip the outdoor workout. A short toilet break followed by indoor enrichment is a better choice than pushing through uncomfortable conditions.
3. Create Shade and a Cool Resting Place
When temperatures rise, give your dog somewhere to recover away from direct sunlight.
At home, choose a well-ventilated indoor area with access to water. Fans and air conditioning can help improve comfort, and cooling mats may offer an additional resting option if your dog finds them comfortable.
If your dog spends time in the garden, provide genuine shade that remains available as the sun moves. A kennel or doghouse can trap heat, so do not assume an enclosed shelter will remain cool simply because it blocks the sun.
The AVMA recommends access to shade and fresh water during warm weather and advises keeping pets indoors when conditions become extremely hot. AVMA: Warm Weather Pet Safety
What about paddling pools and sprinklers?
Some dogs enjoy splashing in a shallow pool or playing with a gentle sprinkler. Others dislike water or become overexcited. Introduce water activities gradually, supervise them closely, and make sure your dog can leave the water easily.
Water play is an optional enrichment activity, not a substitute for shade, rest, or hydration. Choose any water toys according to your dog's size, temperament, and safety needs.
4. Know Whether Your Dog Has a Higher Heat Risk
Some dogs need more careful management in warm weather.
| Higher-risk group | Why extra care matters | Practical approach |
|---|---|---|
| Flat-faced breeds, including Pugs and Bulldogs | Their shortened airways can make heat dissipation more difficult | Keep activity brief and avoid strenuous exercise in warm or humid conditions |
| Puppies and senior dogs | They may be less able to tolerate temperature extremes | Supervise closely and provide frequent opportunities to rest |
| Overweight dogs | Extra body mass can make heat management more challenging | Use gentle activity and follow veterinary weight-management guidance |
| Dogs with heart or respiratory conditions | Underlying disease can reduce tolerance for heat or exertion | Ask your veterinarian for an individualized summer activity plan |
| Dogs with thick, double, or dark coats | Dense or dark coats absorb and retain more heat, but removing the coat can also reduce protection | Brush appropriately and seek professional grooming advice |
A common misconception is that shaving every thick-coated dog will automatically make them cooler. A healthy double coat can help insulate against heat and protect the skin from sunlight. The AKC advises against shaving double-coated breeds solely to cool them down, because doing so may also interfere with normal coat growth. AKC: How Dogs Stay Cool
Regular brushing to remove loose undercoat is generally a better starting point. If your dog has severe matting or a coat-care problem, discuss the appropriate approach with a qualified groomer or veterinarian.
5. Avoid the Parked-Car Risk
Never leave your dog unattended in a parked car during warm weather, even with the windows cracked or the vehicle in partial shade.
A vehicle can heat up rapidly, and shade or an open window cannot reliably keep its interior safe. The AVMA reports that the temperature inside a parked car can rise almost 20°F in just 10 minutes, and nearly 30°F within 20 minutes. Cracking the windows makes almost no difference. The rate depends on conditions, so this figure should not be interpreted as a safe waiting period. AVMA: Pets in Hot Cars
Leave your dog at home when running errands that require you to leave them in a vehicle. During necessary travel, plan stops in advance, use appropriate car restraints, and never assume a short absence is harmless.
6. Recognize Heat Stress Before It Becomes an Emergency
Panting can be normal after exercise, but unusually heavy panting or panting that does not ease with rest can signal trouble.
Watch for:
- Excessive or rapid panting
- Heavy drooling
- Bright red, pale, or bluish gums
- Weakness or unusual lethargy
- Vomiting or diarrhea
- Stumbling, confusion, or difficulty standing
- Collapse or seizures
Do not wait for every symptom to appear. If your dog shows signs of overheating, stop activity and take action immediately.
These signs can indicate heatstroke or another serious condition. You cannot reliably assess the severity by looking at your dog alone.
What to do if your dog overheats
The core principle is simple: wet, then vet. Cooling starts immediately, and transport follows without delay.
- Move your dog out of the heat. Stop all activity and get them into shade or a cool, ventilated area.
- Start cooling immediately. Apply cool running water to your dog's body, soaking the coat to the skin, particularly around the underside. Use a fan or air conditioning to help heat dissipate.
- Contact an emergency veterinarian. If another person is available, ask them to call while you begin cooling.
- Offer water only if your dog is alert and able to swallow normally. Never force them to drink.
- Arrange immediate transport to veterinary care. Keep the vehicle cool and follow the veterinary team's instructions.
If you have a rectal thermometer and are comfortable using it, stop active cooling when your dog's temperature reaches approximately 103.5–104°F (39.7–40°C). If you cannot measure the temperature, cool actively for about 15 minutes while contacting the emergency veterinarian and arranging transport. Do not delay either step to obtain a temperature reading. Keep the vehicle cool and follow the veterinary team's instructions.
Do not use ice baths or delay getting veterinary help to see whether your dog improves. Even if your dog appears to recover after cooling, heatstroke can cause internal injury that is not immediately visible. Veterinary assessment is essential. VCA: Heat Stroke in Dogs
7. What Most Pet Owners Overlook
The most useful summer safety habit is to assess the whole situation rather than relying on one sign.
A dog may still be eager to chase a ball while overheating. A shaded garden may still be humid and uncomfortable. A full water bowl does not mean your dog is drinking enough, and a cooler evening does not guarantee that pavement has cooled.
Build a simple routine around three questions:
Before activity: Is the weather, surface, and route suitable for my dog today?
During activity: Is my dog moving comfortably, breathing normally for the circumstances, and taking breaks?
After activity: Does my dog settle and recover normally, or do the panting, weakness, or unusual behavior persist?
If your dog seems unwell, do not assume heat is the only possible explanation. Contact your veterinarian, especially if you notice a change in drinking, urination, appetite, or energy. Our guide to recognizing dehydration in dogs and cats explains additional warning signs to watch for. For guidance on when a symptom warrants a routine visit versus urgent care, see How Often Should You Take Your Pet to the Vet? A Life-Stage Guide.
Frequently Asked Questions
How do I keep my dog cool in summer?
Provide fresh water, access to shade, a cool resting place, and exercise during cooler hours. Avoid hot pavement and parked cars, and reduce outdoor activity when humidity or heat makes conditions uncomfortable.
What temperature is too hot to walk a dog?
There is no single safe cutoff for all dogs. Temperature, humidity, direct sun, pavement conditions, breed, age, weight, and medical history all matter. If conditions feel oppressive or the ground is hot to the touch, choose a shorter, cooler, or indoor alternative.
Should I shave my dog to keep them cool?
Do not shave a double-coated dog solely to reduce heat. The coat helps insulate and protect the skin. Regular brushing and advice from a veterinarian or qualified groomer are better options for many double-coated breeds.
What are the first signs of heatstroke in dogs?
Warning signs can include heavy panting, excessive drooling, weakness, unusually red or abnormal-colored gums, vomiting, and unsteadiness. Heatstroke is an emergency. Move your dog out of the heat, begin cooling with cool running water, contact a veterinarian, and seek immediate care.
Can I give my dog ice water or frozen treats during summer?
Many healthy dogs can enjoy appropriately prepared frozen treats, and cool drinking water is suitable in warm weather. Treats should use dog-safe ingredients and fit into your dog's diet. If your dog is showing signs of heatstroke, prioritize safe cooling and urgent veterinary care rather than relying on treats.
Conclusion
Learning how to keep your dog cool in summer is about making good decisions before the heat becomes a problem.
Provide clean water, offer shade, check the pavement, adjust exercise to the conditions, and pay particular attention to dogs with higher heat risk. Keep your dog out of parked cars, and learn the warning signs that mean it is time to stop activity and seek help.
You do not need elaborate equipment to create a safer summer routine. Consistent access to water, thoughtful timing, and careful observation provide the foundation. A portable bowl can make hydration easier on the move, while a well-maintained home water station supports everyday access.
Most importantly, let your dog's comfort guide your plans. A shorter walk, a quiet afternoon indoors, or a skipped game of fetch is a sensible choice when conditions are too hot.
