Wet before vet: How to cool dogs safely and effectively
Heat-Related Illness (HRI), also known as heatstroke, is a serious, life-threatening condition in dogs.
- It can happen during or after exercise, in hot weather, or warm environments.
- The longer a dog’s body stays overheated, the higher the risk of severe disease or even death.
Key Findings from Vets Now Clinical Records (2022–2023)
- Over 800 dogs were treated for heat-related illness.
- Only 28% were cooled before transportation to a vet.
- Of those, just 40% were cooled using water.
- Delaying or using ineffective cooling methods can reduce survival chances.
Recommended Cooling Methods
1. Cold-Water Immersion (for healthy, conscious dogs):
- Most effective method.
- No damaging effects observed.
- Use water cooler than the dog — cold is better, but speed is key.
2. Evaporative Cooling (for all dogs, including older, unconscious, or unwell):
- Spray or pour water on the dog.
- Use fans or air conditioning to create airflow.
Transport Tips
- Cool first, transport second.
- Begin cooling before placing the dog in a vehicle.
- Cool the vehicle in advance.
- Ensure good airflow using air conditioning or open windows.
Take-Home Messages
- Wet before vet
- Cool using water
- Seek veterinary advice immediately if your dog shows signs of heatstroke (e.g., excessive panting, reluctance to move, collapse).
- Old advice to “cool slowly” with lukewarm water is a myth.
- Don’t delay — rapid cooling saves lives.
- Prevention is better than cure — avoid outings in hot weather if unsure.
