Why Hot Weather Is Dangerous for Dogs
Dogs handle heat differently from humans. Understanding these differences helps you protect your pet.
Dogs Can't Cool Down Like Humans
Humans sweat: People cool down by sweating all over their bodies. Sweat evaporates and cools our skin.
Dogs pant instead: Dogs have very few sweat glands. They're only on paw pads and don't cool the whole body. Dogs cool themselves primarily by panting.
Panting limitations: When air temperature is very hot, panting doesn't work well. Hot air can't cool your dog effectively. This makes dogs vulnerable to overheating quickly.
Fur coat problem: Dogs wear a permanent fur coat. This traps heat against their skin. Even short-haired dogs have this problem.
Paw Pad Burns
Sensitive paw pads: Dog paw pads are tough but not heat-proof. They're made of thick skin but can still burn on hot surfaces.
Pavement absorbs heat: Asphalt, concrete, sand, and metal surfaces absorb and hold heat from the sun. These surfaces become much hotter than the air temperature.
Severe burns possible: Hot pavement can cause serious burns, blisters, and permanent damage to paw pads within seconds.
Pain and injury: Burned paws are extremely painful. They can lead to infections and difficulty walking.
Heatstroke Risk
Life-threatening condition: Heatstroke occurs when a dog's body temperature rises above 104°F (40°C). Normal dog temperature is 101-102.5°F (38.3-39.2°C).
Happens quickly: Unlike humans who can tolerate higher temperatures for longer, dogs can develop heatstroke in just 10-15 minutes in extreme heat.
Can be fatal: Without immediate treatment, heatstroke kills dogs. Even with treatment, some dogs don't survive or have permanent organ damage.
High-risk dogs: Brachycephalic breeds (short-nosed dogs like Pugs, Bulldogs, Boston Terriers), senior dogs, puppies, overweight dogs, and dogs with thick coats are most vulnerable.
What Temperature Is Too Hot to Walk Dogs?

There isn't one single temperature answer because multiple factors matter. However, general guidelines help you decide.
General Temperature Guidelines
70°F (21°C): This is generally safe for most dogs. Exercise caution with high-risk breeds and very active walks.
75°F (24°C): Use caution, especially for vulnerable dogs. Walk during cooler times of day. Check pavement temperature.
80°F (27°C): Dangerous for many dogs, especially brachycephalic breeds, seniors, and puppies. Walk only early morning or late evening. Always check the pavement.
85°F (29°C): Too hot for most dogs to walk safely. Only very short bathroom breaks in the grass. Avoid pavement completely.
90°F (32°C) and above: Extremely dangerous. Do not walk dogs on the pavement. Even short outdoor time risks heatstroke. Indoor potty alternatives recommended.
The 20°C Question: Is 20 Degrees Celsius Too Hot?
20°C equals 68°F: This temperature is actually quite comfortable and generally safe for dog walking.
Most dogs handle this well: At 68°F, most healthy dogs can walk normally without heat concerns.
Still check pavement: Even at moderate air temperatures, direct sunlight can make pavement hot. Always test surfaces before walking.
Use common sense: If your dog is elderly, has breathing problems, or is a high-risk breed, take precautions even at 68°F.
Good walking weather: 20°C is actually an ideal walking temperature for most dogs.
Humidity Matters Too
Temperature alone doesn't tell the whole story. Humidity makes heat more dangerous.
Why humidity is dangerous: High humidity prevents panting from working effectively. When air is saturated with moisture, dogs can't cool themselves through evaporation.
Heat index: The combination of temperature and humidity creates a "feels like" temperature. This is what truly affects your dog.
Critical combinations:
- 80°F with 90% humidity = Extremely dangerous
- 85°F with 50% humidity = Very dangerous
- 75°F with 80% humidity = Use extreme caution
Check both: Always consider both temperature and humidity before walking your dog.
What Is the 7 Second Rule for Dogs?
The 7-second rule is a simple test to check if the pavement is safe for your dog's paws.
How to Perform the 7 Second Test
Step 1: Go outside to where you plan to walk your dog.
Step 2: Place the back of your hand or your bare foot on the pavement, asphalt, concrete, or sand.
Step 3: Hold it there for 7 full seconds. Count slowly: one-one-thousand, two-one-thousand, three-one-thousand, up to seven.
Step 4: Evaluate what you feel:
- If it's comfortable, the pavement is safe for your dog
- If it's uncomfortably warm, but you can keep your hand there for 7 seconds, walk with caution
- If you must pull your hand away before 7 seconds because it's too hot, the pavement will burn your dog's paws
Result: If you can't comfortably keep your hand on the surface for 7 seconds, it's too hot for your dog to walk on.
Why the 7 Second Rule Works
Similar sensitivity: The back of your hand and bare foot have similar heat sensitivity to dog paw pads.
Quick and easy: This test takes only seconds and requires no special equipment.
Accurate gauge: If it's too hot for your hand, it's definitely too hot for your dog's paws.
Prevents burns: This simple test prevents painful paw pad burns.
Pavement Temperature Facts
Much hotter than air: Pavement can be 40-60°F hotter than the air temperature.
Specific examples:
- Air temp 77°F (25°C) = Pavement can reach 125°F (52°C)
- Air temp 86°F (30°C) = Pavement can reach 135°F (57°C)
- Air temp 87°F (31°C) = Pavement can reach 143°F (62°C)
Burn temperature: Skin destruction begins at 125°F (52°C). Permanent damage occurs within 60 seconds at this temperature.
Surface variations: Asphalt gets hottest, followed by concrete, then brick. Grass stays much cooler. Sand can be extremely hot.
What Temperature Should You Not Walk Dogs?
Based on safety guidelines, here are specific temperature thresholds.
Air Temperature Limits
85°F (29°C): This is the general cutoff for safe dog walking on pavement.
Above 85°F: Pavement reaches dangerous temperatures. The risk of paw burns and heatstroke is very high.
90°F (32°C) and higher: Do not walk dogs on pavement at all. Even grass walks should be very brief and carefully monitored.
100°F (38°C) and above: Keep dogs indoors except for very quick bathroom breaks on grass in shaded areas.
Pavement Temperature Limits
125°F (52°C): This is when skin damage begins. Avoid walking on surfaces this hot.
140°F (60°C) and above: Causes severe burns within seconds. Common on summer pavement when air temp is 85°F or higher.
Special Considerations for High-Risk Dogs
Brachycephalic breeds (Pugs, Bulldogs, Shih Tzus, Boston Terriers, French Bulldogs):
- Limit: 75°F (24°C)
- These dogs overheat very easily due to shortened airways
- Avoid walks above 75°F entirely
Senior dogs and puppies:
- Limit: 80°F (27°C)
- Less ability to regulate body temperature
- More vulnerable to heatstroke
Thick-coated breeds (Huskies, Malamutes, Chow Chows):
- Limit: 70-75°F (21-24°C)
- Heavy coats trap heat
- These dogs are built for cold climates
Overweight dogs:
- Limit: 75-80°F (24-27°C)
- Extra weight makes heat regulation harder
- Higher heatstroke risk
Dogs with health conditions:
- Limit: Varies by condition
- Heart disease, respiratory problems, or other illnesses increase the risk
- Consult your veterinarian for specific guidance
Safe Walking Times in Hot Weather
When temperatures are high, timing your walks makes a big difference.
Best Times to Walk
Early morning: Before 7 AM is ideal. Pavement has cooled overnight. Air temperature is lowest. This is the safest summer walking time.
Late evening: After 8 PM, when the sun is low or set. Give pavement time to cool. Wait at least 2-3 hours after the hottest part of the day.
Coolest hours: Check weather forecasts for daily temperature lows. Plan walks for these times.
Times to Avoid
Midday: 11 AM to 4 PM is the most dangerous time. The sun is strongest. Pavement is the hottest. Air temperature peaks.
Peak heat hours: Generally, 2-4 PM sees the highest temperatures. Absolutely avoid walking during these hours.
After rain in summer: Humid conditions after summer rain make heat more dangerous despite slightly lower temperatures.
Checking Conditions Before Walking
Weather apps: Check temperature and humidity before each walk.
Go outside first: Step outside yourself before getting your dog. Feel the air temperature and test the pavement.
Watch the forecast: Plan your day around predicted high temperatures.
Be flexible: If it's hotter than expected, skip the walk or just do a quick bathroom break.
Signs Your Dog Is Too Hot
Recognizing overheating early can save your dog's life.
Early Warning Signs
Excessive panting: Heavy, rapid breathing with the tongue hanging out far.
Excessive drooling: Much more drool than normal.
Slowing down: Dog walks slower, lags behind, or stops frequently.
Seeking shade: Tries to lie down in the shade, reluctant to continue walking.
Red gums: Gums appear bright red instead of healthy pink.
Increased heart rate: You can feel the heart beating fast if you touch their chest.
Serious Warning Signs (Stop Immediately)
Weakness or collapse: Can't stand properly or lie down and won't get up.
Vomiting or diarrhea: Especially if sudden and during or right after walking.
Disorientation: Seems confused, dizzy, or uncoordinated.
Dark red or purple gums: indicate severe oxygen deprivation.
Glazed eyes: Eyes appear unfocused or dazed.
Rapid breathing then slowing: Breathing becomes shallow or irregular.
Seizures: Extreme emergency requiring immediate veterinary care.
What to Do If Your Dog Overheats
Stop immediately: End the walk right away.
Find shade: Get to a shaded area or indoors quickly.
Cool water: Offer small amounts of cool (not ice cold) water to drink.
Cool them down gradually: Wet their paw pads, belly, and armpits with cool water. Don't use ice or very cold water—this can cause shock.
Airflow: Create air circulation with a fan if available.
Vet immediately: Call your vet or emergency animal hospital. Describe symptoms. Many cases require professional treatment.
Don't delay: Heatstroke progresses quickly. Every minute counts.
Alternatives to Walking in Hot Weather
When it's too hot to walk outside, provide exercise and mental stimulation in other ways.
Indoor Exercise
Indoor play: Throw balls or toys down hallways. Play tug-of-war. Hide and seek provides fun exercise.
Stair climbing: If you have stairs, walk up and down several times. This provides good exercise in a short time.
Training sessions: Practice commands, teach new tricks. Mental exercise tires dogs almost as much as physical exercise.
Indoor dog gyms: Some areas have air-conditioned dog gyms or indoor dog parks.
Water Activities
Kiddie pool: Fill a small plastic pool with cool water. Many dogs enjoy playing in water.
Sprinkler play: Run through sprinklers in your yard. This combines exercise with cooling.
Dog-friendly swimming: Take your dog to a dog beach, dog pool, or lake early morning or evening when it's cooler.
Alternative Outdoor Activities
Grass-only potty breaks: Very quick bathroom trips on grass in shaded areas only.
Shaded walks: Find tree-covered trails or parks. Shade makes a significant temperature difference.
Early morning only: Even in hot climates, very early morning (5-6 AM) is often cool enough.
Mental Stimulation
Puzzle toys: Food puzzle toys occupy dogs for 20-30 minutes and tire them mentally.
Sniff games: Hide treats around the house for your dog to find.
Frozen treats: Make dog-safe frozen treats. Licking and eating them provides entertainment.
Window watching: Let your dog watch birds, squirrels, and neighborhood activity from windows.
Protecting Your Dog's Paws
Even when the air temperature is acceptable, hot pavement threatens paw pads.
Paw Protection Options
Dog booties: Specially designed boots protect paws from hot surfaces. Takes time for dogs to adjust to wearing them.
Paw wax: Products like Musher's Secret create a protective barrier on paw pads. Apply before walks.
Moisturizing paw balm: Keeps paw pads healthy and less prone to cracking from heat.
Walking Surface Choices
Grass: Much cooler than pavement. Choose grass whenever possible.
Dirt trails: Usually cooler than paved surfaces.
Shaded sidewalks: Shade makes pavement significantly cooler.
Avoid: Asphalt parking lots, metal surfaces, sand beaches during hot times.
Long-Term Health and Safety
Build Heat Tolerance Gradually
Spring conditioning: Gradually increase walk length as the weather warms.
Slow adjustment: Don't suddenly take long walks when the heat wave starts.
Know limitations: Some dogs will never tolerate heat well. Accept this and adjust accordingly.
Regular Vet Check-ups
Annual exams: Make sure your dog is healthy before summer arrives.
Discuss heat safety: Ask your vet about your specific dog's heat tolerance.
Update vaccinations: Summer outdoor time increases exposure to other animals and diseases.
Conclusion
Understanding what temperature is too hot to walk dogs is essential for pet safety. Generally, 85°F (29°C) is the limit for safe pavement walking for most dogs, while 90°F (32°C) and above is dangerous for all dogs. Is 20 degrees Celsius too hot to walk my dog? No—20°C (68°F) is actually comfortable and safe for most dogs, though you should still check pavement temperature using the 7-second rule.
At what temperature should you not walk dogs? Avoid walking on pavement when the air temperature exceeds 85°F, the pavement temperature reaches 125°F or higher, or when your dog is at high risk (brachycephalic breeds, seniors, puppies, or thick-coated dogs). Walk during early morning or late evening, test pavement before every walk, watch for overheating signs, and provide indoor alternatives when it's too hot outside.
Frequently Asked Questions
Is 20 degrees Celsius too hot to walk my dog?
No, 20 degrees Celsius (68°F) is not too hot to walk your dog—it's actually quite comfortable and safe for most dogs. This temperature is ideal for dog walking, as it's cool enough that your dog won't overheat easily and warm enough to be pleasant. However, even at this moderate temperature, you should still perform the 7-second pavement test before walking, especially if it's sunny and the pavement has been exposed to direct sunlight for several hours.
What is the 7-second rule for dogs?
The 7-second rule for dogs is a simple test to determine if pavement is too hot for your dog to walk on safely. To perform this test, place the back of your hand or your bare foot flat against the pavement, asphalt, concrete, or sand surface where you plan to walk your dog. Hold it there for a full 7 seconds, counting slowly. If the surface feels comfortable and you can keep your hand there for the entire 7 seconds, the pavement is safe for your dog's paws.
If the surface feels uncomfortably hot and you want to remove your hand before 7 seconds are up, the pavement is too hot and will burn your dog's paw pads. This test works because the back of your hand has similar heat sensitivity to dog paw pads. Remember that pavement can be 40-60°F hotter than the air temperature, so even on moderately warm days (77°F/25°C), pavement can reach 125°F/52°C—hot enough to cause burns within 60 seconds.
What is the hottest temperature I should walk my dog at?
The hottest safe temperature for walking most dogs is approximately 80-85°F (27-29°C), but this depends on multiple factors, including humidity, pavement temperature, your dog's breed, age, health, and coat type. For healthy adult dogs of moderate breeds, 80°F is generally safe if humidity is low, you walk during cooler morning or evening hours, test pavement temperature first, and watch carefully for overheating signs. At 85°F, most dogs should only take very short walks on grass, and pavement should be avoided. Above 85°F, do not walk dogs on pavement at all.
At what temperature should you not walk dogs?
You should not walk dogs when the air temperature exceeds 85°F (29°C) on pavement, or when the pavement temperature reaches 125°F (52°C) or higher, as these conditions create a high risk of paw pad burns and heatstroke. At 90°F (32°C) and above, avoid walking dogs on any paved surfaces entirely—even brief bathroom breaks should be on grass in shaded areas only. When the temperature reaches 100°F (38°C) or higher, keep dogs indoors except for absolutely necessary quick potty breaks on grass.
