If you’ve lived in North Texas for more than a week, you know summer doesn’t mess around.
Triple-digit temperatures, high humidity, blazing afternoon sun, and pavement hot enough to burn bare feet are all part of life across the Dallas-Fort Worth area. While many of us can escape into air conditioning, our dogs depend on us to recognize when it’s simply too hot to be outside.
At Dallas Street Dog Advocates, we’re committed to helping dogs and the people who love them throughout North Texas. Every summer, we see firsthand how quickly the Texas heat can become dangerous for dogs across DFW—from beloved family pets to dogs still searching for their forever homes. Whether you’re heading out for a morning walk, planning a hike, spending the day at the lake, or relaxing by the pool, a little planning can go a long way toward preventing heat-related emergencies.
Knowing how to recognize the signs of heat stroke—and how to prevent it—could save your dog’s life.
Why Heat Is So Dangerous for Dogs
Unlike people, dogs don’t sweat through their skin. They cool themselves primarily by panting, which becomes much less effective during hot, humid Texas weather.
When a dog’s body can no longer cool itself, its temperature rises quickly. Heat stroke is a medical emergency that can cause organ damage, seizures, blood clotting problems, and can become fatal without prompt treatment.
The safest approach is prevention.
Which Dogs Are Most at Risk?
Every dog can overheat, but some are especially vulnerable.
Higher-risk dogs include:
- Brachycephalic (flat-faced) breeds like Bulldogs, Pugs, Boston Terriers, and French Bulldogs
- Senior dogs
- Puppies
- Overweight dogs
- Dogs with heart or respiratory disease
- Thick-coated or dark-colored dogs
- Dogs exercising in hot or humid weather
What About Great Pyrenees?
At Dallas Street Dog Advocates, we rescue many Great Pyrenees and Great Pyrenees mixes. Because they are widely known as livestock guardian dogs that spend much of their lives outdoors, many people assume they naturally tolerate extreme heat.
While a Great Pyrenees’ thick double coat does help insulate them from both hot and cold temperatures, it does not make them immune to heat stroke. Like any breed, they can overheat during a North Texas summer, especially during exercise or prolonged time outdoors.
Help your Pyrenees stay comfortable by providing plenty of fresh water, shade, regular brushing to remove loose undercoat, and limiting outdoor activity to the cooler parts of the day. Although it may seem counterintuitive, double-coated breeds should not be shaved unless recommended by your veterinarian for a medical reason. Their coat helps regulate body temperature and also protects their skin from the sun.
Signs of Heat Stroke
Heat stroke can progress rapidly.
Early warning signs include:
- Excessive panting
- Thick drool
- Bright red gums or tongue
- Slowing down during walks
- Refusing to continue walking
- Restlessness
- Seeking shade
- Drinking excessively
As heat stroke worsens, you may notice:
- Vomiting or diarrhea
- Weakness
- Stumbling
- Confusion
- Collapse
- Seizures
- Difficulty breathing
If your dog reaches this stage, it is a veterinary emergency.
How to Prevent Heat Stroke
Fortunately, prevention is usually simple.
Walk Early
In DFW, sunrise is often the safest time for walks during the summer. Even evenings may remain dangerously hot because pavement and concrete retain heat long after sunset.
Test the Pavement
If it’s too hot for the back of your hand for seven seconds, it’s too hot for your dog’s paws.
Remember that artificial turf can become even hotter than concrete.
Always Bring Water
Carry fresh water and a collapsible bowl anytime you’re outside.
Choose Shade
Whether you’re hiking, visiting a park, or attending an outdoor event, look for shaded areas and allow frequent cooling breaks.
Skip Strenuous Exercise
Fetch, running, hiking, and long walks should wait for cooler temperatures.
Some energetic dogs will happily keep playing even after they’re overheating—don’t rely on your dog to know when to stop.
Never Leave a Dog in a Parked Vehicle
Even with cracked windows, temperatures inside a vehicle can become deadly within minutes.
What To Do If You Think Your Dog Is Overheating
If your dog is showing signs of heat stroke:
- Move them immediately into shade or air conditioning.
- Stop all activity.
- Wet them with cool (not ice-cold) water, especially around the belly, groin, neck, and paws.
- Offer small amounts of water if they are alert and able to drink.
- Turn on a fan or vehicle air conditioning if available.
- Contact your veterinarian or emergency veterinary hospital immediately.
Even if your dog appears to recover, internal organ damage can continue after body temperature comes down.
What NOT To Do
Avoid these common mistakes:
- Don’t wait “to see if they improve.”
- Don’t force water into your dog’s mouth.
- Don’t resume the walk once they’ve cooled off.
- Don’t leave wet towels draped over your dog for extended periods, as they can trap heat.
- Don’t assume thick-coated dogs are naturally protected from Texas heat.
When Should You Go to the Vet?
Go to a veterinarian immediately if your dog has:
- Persistent heavy panting
- Vomiting or diarrhea
- Difficulty breathing
- Weakness or inability to stand
- Collapse
- Confusion
- Seizures
- Symptoms that don’t quickly improve after cooling begins
Heat stroke is always safer to treat early than to wait until symptoms become severe.
Pools and Lake Days: Popular in DFW, But Keep Safety in Mind
Many North Texas families spend summer days by the pool or at area lakes. While water can be a great way for dogs to cool off, it doesn’t eliminate the risk of heat-related illness.
Pools
Swimming is excellent exercise for many dogs, but keep these tips in mind:
- Always supervise your dog around the pool.
- Not every dog instinctively knows how to swim.
- Make sure your dog knows where the steps or exit are before allowing free swimming.
- Rinse chlorine from your dog’s coat after swimming.
- Provide fresh drinking water so your dog isn’t tempted to drink pool water.
Lakes
Whether you’re visiting White Rock Lake, Grapevine Lake, Lake Lewisville, or another North Texas destination, remember to:
- Bring plenty of fresh water.
- Provide shade and frequent rest breaks.
- Watch for hot docks, boat surfaces, and fishing hooks.
- Keep your dog away from water that appears green, scummy, or resembles spilled paint, which may indicate harmful blue-green algae.
Even when swimming, dogs can still become overheated after long periods of activity in the Texas sun.
A North Texas Summer Doesn’t Have to Keep You Inside
Summer adventures are still possible—you just have to plan around the heat.
Choose early morning walks, keep fresh water nearby, avoid hot pavement, and pay close attention to your dog’s behavior. Knowing the signs of heat stroke and acting quickly can make all the difference.
At Dallas Street Dog Advocates, we’re committed to helping dogs stay safe in every season. Whether you’ve recently adopted, are fostering, or have shared your life with dogs for years, a little extra caution during a Texas summer can help keep tails wagging well into fall.
