🐶 Preventing Heat Stroke in Dogs During High UK Temperatures

Published on 17 July 2025 at 10:08

📈 Why Now?

The UK has recently experienced another intense heatwave, with temperatures soaring above 30–35 °C in many areas. Tragically, there have been cases where dogs have died from heat stroke—particularly when left in parked cars or exercised during peak heat. These incidents are a stark reminder: our dogs are especially vulnerable in extreme weather.

🚫 Why Is It So Dangerous?

  • Dogs cannot sweat like humans—they mainly cool down through panting, which is much less effective in high heat.

  • Flat-faced breeds (like French Bulldogs and Pugs), dogs with thick coats, the elderly, overweight dogs, or those with health conditions are especially at risk.

  • Even on days as mild as 22 °C, dogs can begin to overheat—especially if exercised. Once temperatures rise above 25 °C, the risk of heat stroke increases significantly, and in some cases, collapse, seizures, or organ failure can occur within minutes.

⚠️ Know the Warning Signs

  • Excessive panting

  • Drooling

  • Vomiting or diarrhoea

  • Lethargy or collapse

  • Red or very pale gums

  • Confusion or wobbliness

If you notice any of these signs:

  1. Move your dog to a shaded area.

  2. Start cooling with water and airflow.

  3. Offer small sips of water.

  4. Take your dog to a vet, even if they seem to recover—heat stroke can have delayed effects.

✅ Cooling Safely and Effectively

Here’s how to cool your dog properly without putting them in shock or worsening the situation:

  1. Cool First, Transport Second
    If your dog shows signs of overheating, start cooling immediately. Don’t delay by rushing to the vet without first bringing their temperature down.

  2. Use Cool (Not Icy) Water
    If possible get them to sit in cool tap water so it covers their belly, making sure the limbs and chest are cooled. Avoid pouring over their head or whole coat. You can also fan them while damp to help with evaporation.

  3. Avoid Wet Towels Over the Body
    Don’t cover your dog with wet towels—they can trap heat. Instead, place the towel underneath or have your dog lie on a cool, damp surface.

  4. Hydration & Shade
    Make sure your dog always has access to fresh, cool water. Offer small amounts frequently, and use shaded or well-ventilated spaces indoors or outside.

  5. Be Pavement-Aware
    Pavements and artificial grass can get dangerously hot. If you can't hold your hand on the ground for 5 seconds, it's too hot for your dog's paws.

  6. Walk Only in the Coolest Parts of the Day
    Schedule walks early in the morning or later in the evening when temperatures are significantly lower. Avoid walks in the middle of the day.

  7. Use Cooling Aids
    Cooling mats, elevated beds, damp flannels, or small paddling pools can help. You can also freeze treats or toys to help keep your dog cool and entertained.

💡 Extra Safeguards at Home

  • Never leave your dog in a car, even for a short time. Interior temperatures can soar quickly.

  • Create a cool zone in your home with fans, mats, and water bowls.

  • Groom thick-coated dogs carefully, but don’t shave them—fur provides insulation.

  • Monitor indoor temperatures too, especially in conservatories or sun traps.
