Heatstroke and Panting: Signs Every Dog Owner Must Know
Panting is a dog’s natural way to cool down, but under certain conditions, it can signal a serious, life-threatening emergency: heatstroke. Recognizing the signs early can save your dog’s life.
What Is Heatstroke in Dogs?
Heatstroke happens when a dog’s body temperature rises dangerously high — usually above 104°F (40°C). It often occurs during hot weather, especially when dogs are left in cars, walk on hot pavement, or overexert themselves during the heat of the day.
Since dogs can’t sweat like we do, they rely heavily on panting. When panting isn’t enough to lower their body temperature, heatstroke sets in quickly.
Early Warning Signs of Heatstroke
Look for these red flags:
-
Excessive, rapid panting
-
Bright red or very pale gums
-
Thick, sticky saliva
-
Weakness or collapse
-
Vomiting or diarrhea
-
Disorientation or seizures
Why Panting Alone Isn’t Enough
As heat rises, panting becomes less effective at cooling the dog. In humid conditions, evaporation slows down, making it even harder for panting to work properly. This is why dogs are at such high risk for overheating during summer months.
Immediate Steps if You Suspect Heatstroke
If you see signs of heatstroke:
-
Move your dog to a cool, shaded area immediately.
-
Offer cool (not ice-cold) water to drink.
-
Wet your dog’s body with cool water, focusing on the belly, armpits, and paws.
-
Use a fan to help evaporate water from their body.
-
Get to a vet immediately — heatstroke is a true emergency.
Do not use ice water, as it can cause blood vessels to constrict and worsen the situation.
How to Prevent Heatstroke
-
Never leave dogs in cars — even for a minute.
-
Avoid walks during the hottest parts of the day.
-
Provide shade and constant access to water outside.
-
Know your dog’s limits — brachycephalic (flat-faced) breeds like Bulldogs are especially prone to overheating.
Final Thoughts
Panting is a vital warning system. Recognizing when panting crosses from normal cooling to signs of heatstroke could save your dog’s life. Stay alert, especially in the heat, and act quickly if you notice anything unusual.
