Heatwave Alert: How to Keep Your Dog Safe During Extreme Temperatures

Dogs Are More Sensitive to Heat Than You Think

When temperatures climb above 40°C (104°F), dogs are at high risk of heat-related distress. Unlike humans, they can’t sweat to regulate their body temperature. Their only cooling mechanisms are through their paw pads and rapid panting.

Some breeds are especially vulnerable. Brachycephalic (flat-faced) dogs such as Bulldogs, Pugs, Shih Tzus, and Boxers are significantly more prone to heatstroke due to restricted airways. Elderly dogs, puppies, overweight animals, and those with heart or respiratory conditions are also at heightened risk.

Their close proximity to the ground exposes them to the highest layer of heat, especially on surfaces like asphalt, cement, or sand.

Did you know? At just 25°C (77°F) in the shade, asphalt can reach over 50°C (122°F). That’s enough to cause second-degree burns in less than 60 seconds.

Recognizing the Signs of Heatstroke in Dogs

Heatstroke can be fatal within minutes, and many pet owners miss early symptoms. Here’s what to look out for:

• Excessive panting or drooling
• Red or pale gums
• Lethargy or weakness
• Vomiting or diarrhea
• Disorientation or collapse
• Seizures or unconsciousness

If you suspect heatstroke, act fast:

1. Move the dog to a cool, shaded area.
2. Wet them with cool (not cold) water—especially on the paws, neck, and belly.
3. Use a fan if possible to increase evaporation.
4. Offer small amounts of water to drink.
5. Call a veterinarian immediately.

Important: Never use ice or ice-cold water. This can shock the system and worsen the condition.

Burnt Paw Pads: The Invisible Summer Threat

Hot sidewalks can be deceptively dangerous. Dogs’ paws are sensitive and vulnerable to burns when exposed to overheated surfaces.

To test the ground, place the back of your hand on the surface for 7 seconds. If it’s too hot for you, it’s too hot for your dog.

Alternatives:

• Stick to grassy, shaded routes.
• Use protective dog booties.
• Walk early in the morning or after sunset.

Pro Tip: Cooling mats or vests can also help regulate your dog’s temperature during outings.

Walks and Cars: Fatal Errors to Avoid

Avoid walks from 11 a.m. to 4 p.m., when the sun and surface temperatures are at their peak. Even in shaded areas, radiant heat can overwhelm your dog’s natural cooling capacity.

Never leave your dog in a parked car—not even for five minutes, not even with the windows cracked. Inside temperatures can rise by over 20°C (68°F) in 10 minutes and lead to death.

Every year, dozens of dogs die unnecessarily due to being locked in hot vehicles.

Swimming Can Help—But Be Cautious

A refreshing swim can help dogs cool off, but it comes with conditions:

Safe locations:

• Flowing rivers, lakes with clean water, or shaded garden pools
• Avoid stagnant water, which may contain cyanobacteria (blue-green algae), often deadly to dogs.

Other water-related risks:

• Leptospirosis: A potentially fatal bacterial infection spread via animal urine in ponds or lakes.
• Saltwater ingestion: Causes dehydration, vomiting, and electrolyte imbalance—especially after seawater swims.
• Hot sand or concrete pool decks: These can burn paw pads as easily as asphalt.

Always rinse your dog with fresh water after a swim—especially in the sea or a public pool.

Sunscreen for Dogs? Yes, Really

Dogs with light-colored or thin fur are susceptible to sunburn, especially on the nose, ears, and belly. Pet-safe sunscreens exist and should be used if your dog will be in the sun for extended periods.

Avoid human sunscreen: many contain zinc oxide or PABA, both toxic to dogs if ingested.

Equipment That Can Make a Big Difference

• Cooling vests and neck wraps
• Elevated dog beds (to allow airflow)
• Collapsible water bowls for walks
• Protective booties
• Fans or misting systems in kennels or patios

The Ultimate Checklist to Protect Your Dog During a Heatwave

✅ Avoid walks between 11 a.m. and 4 p.m.
✅ Stick to shaded areas, and walk early or late in the day
✅ Never leave your dog in a car, even for a moment
✅ Keep fresh, cool water available at all times
✅ Test surfaces before walking—use grass or booties
✅ Provide cool indoor spaces with fans or AC
✅ Use cooling mats or wet towels to help lower body temperature
✅ Be extra cautious with elderly, flat-faced, or sick dogs
✅ After swimming, rinse thoroughly with clean water
✅ Watch for signs of heatstroke—act immediately
