Summer Safety Tips for Your Pet: Heatstroke Prevention

As temperatures rise and sunny days become the norm, it’s important to keep your pet’s health and safety top of mind. While summer offers plenty of opportunities for outdoor fun, it also brings significant risks—especially heatstroke. Dogs and cats can quickly overheat, and because they don’t regulate temperature like humans, hot weather can be more dangerous than many pet owners realize.

Understanding the signs of heatstroke and taking proactive steps can prevent serious health issues—or even save your pet’s life. Here’s how to enjoy the summer season while keeping your furry friend safe and comfortable.

What Is Heatstroke in Pets?

Heatstroke is a serious condition that occurs when a pet’s body temperature rises to dangerous levels, typically above 103°F (39.4°C). Unlike humans, pets don’t sweat to cool down. Dogs pant and cats seek shade or cool surfaces, but these methods aren’t always enough during extreme heat.

If left untreated, heatstroke can lead to organ failure, brain damage, or death.

1. Avoid the Hottest Parts of the Day

The sun is strongest between 10 a.m. and 4 p.m., and temperatures can spike quickly—especially on pavement, which absorbs and radiates heat.

Prevention tips:

• Walk your dog early in the morning or late in the evening.
• Keep pets indoors during peak heat hours.
• Always check the ground with your hand—if it’s too hot for your palm, it’s too hot for paws.

Note: Dogs with flat faces (brachycephalic breeds like Pugs and Bulldogs) are especially prone to heatstroke and should be monitored closely.

2. Keep Your Pet Hydrated

Water is your pet’s best defense against heat exhaustion. Dehydration can set in quickly, especially after exercise or time spent outside.

Hydration tips:

• Ensure fresh, clean water is always available indoors and out.
• Bring a collapsible bowl and bottled water when walking or traveling.
• Offer ice cubes as a fun and cooling treat.

Adding wet food to your pet’s diet can also help boost their water intake on hot days.

3. Never Leave a Pet in a Parked Car

Even on a mild day, the inside of a car can reach lethal temperatures in just minutes. Cracked windows don’t provide enough airflow to make a difference.

Facts to know:

• On an 85°F (29°C) day, the interior of a car can hit 102°F (39°C) in just 10 minutes.
• In 30 minutes, it can soar to 120°F (49°C) or higher.

What to do: If you see a pet locked in a car, alert authorities immediately. Many regions have laws protecting animals in these situations.

4. Provide Shade and Ventilation

If your pet spends time outside, they must have access to shade that’s well-ventilated—like a covered porch or a shaded area under trees.

Avoid using doghouses or enclosed shelters, which can trap heat and make conditions worse.

Better options:

• Use pop-up tents or shade sails in the yard.
• Place cooling mats in shaded areas.
• Set up a shallow kiddie pool for supervised splashing.

5. Recognize the Signs of Heatstroke

Early detection is critical in preventing severe outcomes. Always monitor your pet for changes in behavior or physical signs of heat stress.

Symptoms of heatstroke:

• Excessive panting or drooling
• Bright red gums or tongue
• Lethargy or weakness
• Vomiting or diarrhea
• Collapse or unresponsiveness

Immediate action: Move your pet to a cool area, offer water, and gently cool their body with wet towels (especially the neck, armpits, and paw pads). Avoid ice-cold water, as it can cause shock. Contact your veterinarian right away—even if your pet seems to recover.
