Preventing heat stroke in dogs (UK summer guide)

UK summer heat stroke is preventable — walk early/late, never leave dogs in cars, use 5-second pavement test, and cool with damp towels at the first signs.

Dog

Recognise the signs

  • Heavy panting, drooling
  • Bright red gums
  • Seeking cool surfaces
  • Reluctance to walk further
  • Wobbliness — emergency, see dog-heat-stroke

First aid steps

  1. Walk before 8am or after 7pm in summer.
  2. 5-second pavement test — back of hand on surface for 5 seconds; if too hot, too hot for paws.
  3. Carry water on every walk.
  4. Provide shade in garden.
  5. Cool damp towels on belly, paws, groin if dog seems hot.
  6. Cool damp coat (not wet wrap).

Do NOT

  • Never leave a dog in a parked car, even briefly.
  • Do not exercise hard in heat.
  • Do not assume green grass is cool — it can still be 35°C+ on hot days.
  • Do not use ice baths.

When to phone the vet immediately

  • Wobbliness, vomiting, glassy stare — see dog-heat-stroke; emergency.

Prevention

  • Time of day matters more than weather forecast.
  • Pavement test always.
  • Carry water, collapsible bowl, cooling vest if prone.
  • Brachycephalic breeds — extra caution from 20°C upwards.
  • Acclimatise gradually — first hot weeks of summer are highest risk.

Breed-specific notes

  • Highest risk: Bulldogs, Pugs, French Bulldogs, Boxers, Shih Tzus, thick-coated breeds, very young, very old, very overweight.

Frequently asked questions

What temperature is too hot?

Depends on coat, breed, humidity. Brachycephalic breeds struggle from 20°C; most dogs need caution above 24°C. Humidity multiplies risk.

Cooling coat or damp towel?

Either works — damp towels reapplied are very effective. Cooling coats convenient on the move.

Can dogs swim safely in hot weather?

Yes, with safety considerations (water intoxication, blue-green algae, drowning risk). Brief swims with breaks beat long fetch sessions.
