Heatstroke in Dogs – Spotting the Signs and Acting Fast  

Heatstroke in dogs is a serious, life-threatening emergency that can develop very quickly, especially in warm weather. At Oathall Vets, we want you to know how to prevent, recognise, and respond to this dangerous condition. 

What is Heatstroke? 

Heatstroke occurs when a dog’s body temperature rises dangerously high and they can no longer cool themselves effectively. It can result in organ failure or even death if not treated quickly. 

Signs of Heatstroke in Dogs 

• Excessive panting or drooling 

• Red or pale gums 

• Weakness or collapse 

• Vomiting or diarrhoea 

• Confusion or seizures 

• High body temperature (above 39.5°C/103°F) 

Dogs at Higher Risk: 

• Flat-faced breeds (like Bulldogs or Pugs) 

• Older dogs or those with health conditions 

• Overweight dogs 

• Dogs left in cars or hot rooms 

• Dogs walked during the hottest part of the day 

What to Do If You Suspect Heatstroke 

1. Move your dog to a cool, shaded area immediately 

1. Pour or hose cold water over them (NB Run the water through the hose first to ensure it is cold) 

1. Do not drape in towels- keep the cold water flowing 

1. Call Oathall Vets immediately for emergency help 

1. When you bring your dog down to the clinic travel in a cold air-conditioned car (windows open if air-conditioning unavailable) 

Never: 

• Delay veterinary care 

• Assume your dog will recover without treatment
