My dog has heatstroke — what now?

Heatstroke is an emergency, and short-muzzled breeds are at higher risk. Do not wait for the dog to "rest it off".

First, how urgent is this?

Go now

  • Any suspected heatstroke: go now.
  • Short-muzzled breeds (French Bulldog, Pug and others) are at higher risk.
  • Fast breathing, heavy drooling, a bright red or purple tongue.
  • Wobbling, seizures or collapse.

Contact your vet today

  • Was in heat or a stuffy space, panted but seems back to normal: still needs a check today.
  • Brief sun exposure with normal drinking and energy, followed by vomiting or diarrhoea.

Record and observe

  • Panting more than usual after being outdoors, settling with rest and water, normal for the rest of the day: record it and avoid long exposure again.
  • A dog with known heart or breathing disease under vet care: record any increase in panting and go back for a review.

Before you set off

  • Move the dog somewhere cool and ventilated, wet its body with room-temperature water, and set off; do not use ice water or alcohol, and do not wrap it in a towel or blanket.
  • When it started, the surroundings (car, outdoors, indoor ventilation) and the rough temperature.
  • Whether there was vomiting, diarrhoea or a seizure.
  • A list of medicines and the time of the last dose.
  • Do not give human medicine; do not let the dog drink a large volume at once.

What your vet may ask and do

  • Ask: when it started and where the dog was.
  • Ask: any vomiting, diarrhoea, seizure or loss of consciousness.
  • Do: temperature, circulation and hydration assessment.
  • Do: blood tests (electrolytes, kidney values, clotting).
  • Do: fluids and active cooling, with admission for severe cases.
  • Do: monitor for organ damage that shows up later.
