During hot weather, heatstroke can develop very quickly in dogs and can become life-threatening within minutes. Knowing what to do in those first moments can make a huge difference. Heatstroke is a veterinary emergency, but while you are waiting for help, the way you cool the dog is extremely important.
Early signs of heatstroke include:
• Heavy, rapid panting
• Excessive drooling
• Restlessness or confusion
• Bright red gums or tongue
• Weakness or stumbling
• Vomiting or diarrhoea
• Collapse
If you notice these signs, act immediately.
What to do straight away
1. Move the dog out of the heat
Get the dog into shade or, ideally, a cool, well-ventilated indoor area. Avoid direct sunlight completely.
2. Start gentle cooling
Use cool (not ice-cold) water to wet the dog’s body. Focus on:
Belly area
Armpits
Paw pads
Neck and chest
You can also use damp towels, but do not wrap the dog tightly as this can trap heat.
A fan can help increase cooling through evaporation.
3. Offer small amounts of cool water
Allow the dog to drink if they are conscious and able, but do not force water.
4. Monitor closely
Stay with the dog at all times and watch for changes in breathing, alertness, or collapse.
What NOT to do
- Do not use ice baths or freezing cold water
- Do not cover the dog completely in wet towels for long periods
- Do not delay veterinary treatment while trying to cool the dog
- Do not force food or water
Very cold water can cause blood vessels to constrict, which actually slows effective cooling.
Always seek urgent veterinary help
Even if your dog seems to improve, heatstroke can cause internal damage that is not immediately visible. Always contact a vet straight away.
In the UK, emergency veterinary services are available 24/7, and heatstroke cases are treated as critical.
Prevention is always best
The safest approach is avoiding overheating in the first place:
✔ Walk dogs early morning or late evening
✔ Avoid hot pavements
✔ Provide constant access to shade and water
✔ Never leave dogs in cars or conservatories
✔ Limit exercise during heatwaves
