As we head into mid-June, many of us are already bracing for rising temperatures. While we reach for the AC and iced lattes, our furry companions are facing a much higher risk. Unlike humans, dogs can’t cool down as easily and are much more susceptible to heat-related illnesses. One of the most serious and fast-acting threats is heatstroke, a life-threatening condition that every dog owner should be prepared to prevent and respond to.

In this post, we’ll break down what heatstroke really looks like, how to protect your dog, and what to do if the unthinkable happens, so you and your pup can enjoy the season safely.

Understanding Why Dogs Struggle with Heat and How Heatstroke Occurs in Dogs

Unlike humans, dogs can't sweat through their skin to cool down. They rely almost entirely on panting and a few small sweat glands in their paw pads. When the air is hot and humid, panting becomes less effective, and their internal temperature can skyrocket.

A dog’s normal temperature is between 101°F and 102.5°F. Heatstroke occurs when a dog’s body temperature rises to dangerous levels, usually above 104°F (40°C), and their cooling systems can’t keep up, they are considered in the danger zone for heatstroke, which can lead to organ failure, seizures, and death.

While every dog can get heatstroke, some are at much higher risk. Here is some on our high-risk hot list:

Flat-faced (Brachycephalic) breeds: Flat-faced dogs like Pugs, Bulldogs, and Frenchies struggle to move air efficiently.

Senior dogs, puppies, & those with serious health issues: Their bodies can't regulate temperature as well.

Overweight Dogs: Extra body fat acts as insulation and puts more strain on the heart.

Thick Coats: Huskies, Shepherds, and Newfoundlands are essentially wearing a winter parka in July.

Common causes to remember:

Being left in a hot car (even for just a few minutes)
Intense exercise in warm weather
Lack of shade or water during outdoor activities
Walking on hot pavement that increases overall body temperature

Recognizing the Signs of Heatstroke

Knowing the signs of heatstroke could mean the difference between life and death for your dog. Heatstroke can escalate quickly, so it’s important to act as soon as you notice something is off.

Early warning signs include:

Excessive, heavy panting
Drooling more than usual or Thick, ropey saliva
Bright red gums or tongue
Restlessness, agitation, or searching for shade
Rapid heart rate
Mild weakness or wobbliness

As the condition progresses, symptoms can become much more serious:

Advanced signs:

Vomiting or diarrhea (sometimes with blood)
Lethargy, confusion, or "glassy" eyes
Staggering or collapsing
Seizures
Loss of consciousness

If you see any of these symptoms, especially in warm weather or after physical activity, take it seriously and act immediately.

Responding to Heatstroke: What to do NOW

If you suspect your dog is suffering from heatstroke, quick and calm action is essential. Heatstroke is a medical emergency, and every second counts.

Immediately move your dog to a cooler area.
Get them out of the sun and into the shade or a space with air-conditioning as soon as possible.
Begin cooling your dog slowly.
Use cool (not cold) water to wet your dog’s body. You can use a hose, wet towels, or place them in a shallow pool or tub. Focus on areas like the belly, paws, groin, neck, and armpits. Avoid using ice or ice-cold water, as this can constrict blood vessels and actually trapping heat inside the body.
Offer small amounts of water.
Let your dog drink cool water in small sips if they’re alert and able—but don’t force them to drink.
Use a fan if available.
Circulating air across a wet dog helps bring their body temperature down more effectively.
Get to a veterinarian immediately.
Even if your dog starts to look better, internal damage may already be occurring. A vet needs to assess your dog and provide supportive care like IV fluids, oxygen, and monitoring.

Heatstroke is not something to "wait and see" quick action and professional help can save your dog’s life.

Prevention: More Than Just "Leaving the Windows Down"

The best way to protect your dog from heatstroke is to take proactive steps to avoid overheating in the first place. Simple habits can go a long way in keeping your dog safe.

Avoid peak heat hours.
Walk your dog early in the morning or later in the evening when temperatures are cooler. Always check the pavement temperature—if you can’t hold the back of your hand on the pavement for 7 seconds, it’s too hot for your dog’s paws.
Provide shade and fresh water.
Whether at home or on the go, make sure your dog has access to a shady spot and plenty of clean, cool water at all times.
Never leave your dog in a parked car.
Even with the windows cracked, temperatures inside a car can skyrocket to over 100°F in minutes and become deadly, even on mild days.
Adjust exercise based on weather.
Reduce intensity and duration of physical activity during hot days. Choose grassy areas, bring water, and take frequent breaks.
Invest in cooling gear.
Cooling mats, vests, bandanas, and elevated beds can help regulate your dog’s temperature when it’s hot out. They're especially helpful on road trips, during outdoor activities, or for dogs who overheat easily.
Consider your dog’s breed and health.
If you know your dog is at a higher risk of heat stroke, be extra cautious and talk to your vet about safety guidelines.

Keeping Our Dogs Safe

Summer adventures with your dog can be a blast, but they come with responsibility. Heatstroke is dangerous and fast-acting, but with the right awareness, preparation, and quick action, it's also preventable.

Take the time to recognize the signs, prepare your gear, and plan your outings wisely. Your dog counts on you to keep them safe and when you do, you both get to enjoy more fun in the sun, worry-free.
