Heat Stroke Is No Joke: What to Watch Out for This Summer
Heat stroke in dogs is serious and with record-high temps across New England and beyond, it’s more relevant than ever. This post covers what heat stroke actually is and how to spot early warning signs—including what to do in the moment, and the steps you can take to prevent it.
Summer’s Heating Up, and Our Dogs Are Feeling It More Than We Think
While we can reach for cold drinks or spend time in the A/C, our dogs don’t have the same cooling options. Heat stroke is a medical emergency that can sneak up fast, and it doesn’t just happen in locked cars (though still tragically common).
It can happen during a walk, in the backyard, or even while relaxing in a sunspot inside the house. Dogs won’t always stop themselves when they’re too hot, and it’s our responsibility to recognize the signs before things turn dangerous.
What Heat Stroke Is and Why It Happens
This condition occurs when a dog’s internal body temperature rises to dangerous levels and they can’t bring it down on their own. Since dogs don’t sweat like humans do, they rely heavily on panting to release and regulate heat. In extreme heat or humidity, panting alone isn’t always enough.
A normal dog’s temperature is between 101–102.5°F (38.3–39.2°C)
104°F (40°) or higher signals a dangerous level, requiring emergency care
Dogs at higher risk include:
Short-nosed (brachycephalic) breeds like Bulldogs, Pugs, and Frenchies
Older and/or overweight dogs
Dogs with heart or respiratory conditions
Puppies and high-energy breeds who may not self-regulate during play
Did You Know? Even healthy, active dogs can overheat under the right conditions—especially if they’re exposed to heat and humidity without enough shade, water, or rest.
Signs of Overheating in Dogs
Recognizing the early signs of a heat stroke is key to acting fast and potentially saving your dog’s life. Some of these symptoms may be mild at first, but can progress very quickly.
Common signs include:
Excessive panting or drooling
Wobbling, weakness, or general unsteadiness
Disorientation, confusion, or appearing “out of it”
Pro Tip: If your dog is actively seeking cool surfaces like tile floors or digging into shaded ground, it may be an early attempt to regulate their temperature—something that should be taken seriously.
What To Do In An Emergency
Time matters. If you suspect your dog is experiencing a heat-related crisis, take the following steps immediately:
Move your dog to a cooler environment: Indoors with air conditioning, a shaded area, or a well-ventilated car with A/C running.
Apply cool (not cold) water to their body: Focus on their paws, underarms, stomach, and ears.
Encourage slow, small sips of water: Don’t force them to drink, and avoid large amounts at once.
Use a fan or airflow to help with cooling: Air circulation helps the water evaporate and reduce body temperature more efficiently.
Call your vet or head to the nearest emergency clinic: Even if your dog seems to improve, heat-related illness can cause internal damage that requires professional monitoring.
Avoid These Common Mistakes:
Avoid ice baths or using ice packs directly on your dog
Do not wait to see if symptoms improve on their own and always consult your vet
How To Prevent Heat-Related Emergencies
The most effective treatment is prevention. With a few adjustments, you can help keep your dog comfortable and safe even on the hottest summer days.
Walk early or late in the day when temps are cooler
Use the 5-second rule for pavement—if it’s too hot for your hand, it’s too hot for your pup’s paws. Using specially formulated balms or boots can help.
Make fresh, cool water available at all times
Skip high-intensity/outdoor play during peak heat hours
Keep dogs indoors with airflow and shade, especially if you live in a humid climate
Never leave your dog in a parked car, even with the windows cracked
Final Thoughts
Heat stroke is fast, dangerous, and often preventable. Knowing what to look for and how to respond gives you the power to protect your dog in dangerous weather.
Whether you have a high-drive working breed or a laid-back lap dog, summer heat poses risks that we, as pet parents, need to stay ahead of. Be mindful, stay prepared, and don’t hesitate to cut a walk short or stay in the shade.
Our dogs can’t say, “I’m too hot,” but they’re counting on us to recognize when something’s not right.
