Excellent advice from The Veterinary Wellness Centre
Important info for anyone enjoying the sun this weekend at P in the Park or our lovely local beaches ☀️
🐾 Heatstroke: the lowdown
🏃♂️Exercise, not hot cars, is the #1 cause
RVC research found exertional heatstroke accounts for around 3 in 4 heatstroke cases in UK dogs — far more than hot cars or hot weather alone. Walking, playing, and running with your dog is the biggest risk factor, not just leaving them somewhere hot.
💦It's not just about temperature — humidity matters too
🌡️ Dogs cool mainly by panting, not sweating
💧 Panting relies on evaporation — in humid air, that moisture has nowhere to go
⚠️ Above ~35% humidity, panting gets less effective. Above ~80%, it barely works
🔥 High heat + high humidity = the most dangerous combo
💨Dry air isn't "safe" either
Low humidity pulls moisture straight out of a dog's breath. Combined with exercise, water loss can jump 10–20x — dehydration risk climbs fast.
🕑"Walk early or late" isn't the full answer
Mornings and evenings are often more humid, not less. A dog can struggle more at 17°C/90% humidity than at 25°C/30% humidity.
🐶Flat-faced breeds (French Bulldogs, Pugs, Boxers, etc.) are at much higher risk
Their airway shape makes panting far less efficient — they overheat faster and with less warning, even in moderate conditions.
❗️If you suspect heatstroke:
🚨 Get them wet, straight to the vet
Use cold water, not tepid — the colder the better, use whatever's available (paddling pool, hose, bath)
Immerse or pour water over them, focusing on the whole body
Support the head if the dog is unsteady or flat-faced, to avoid water aspiration
Don't wait to "finish" cooling before leaving — cool on the way if you can
Bottom line:
✅ Exercise is the leading trigger — match intensity to conditions
✅ Check humidity, not just temperature
✅ Extra caution with flat-faced breeds
✅ Hydrate every 15–20 mins on warm walks
✅ Cold water immersion is the fastest, safest first response
✅ Cool first, transport second — then get to the vet regardless
