The Hidden Danger: Why You Should Never Leave Your Dog in the Car on a Hot Day

Leaving your dog in a parked car on a warm day—even for just a few minutes—can be fatal. Temperatures inside a vehicle can soar rapidly, putting your dog at risk of heatstroke and even death. Learn the dangers, signs of overheating, and safe alternatives to protect your four-legged friend.

The Deadly Truth: Hot Cars and Dogs Don’t Mix

As temperatures rise, so does the risk to our pets. Every year, hundreds of dogs suffer and die from being left in hot cars. Even on a mild day, a parked car can quickly become a deadly oven—and cracking the window doesn’t do much to help.

How Hot Is Too Hot?

You might think it’s safe to leave your dog in the car for “just five minutes,” but consider this:

Dogs cannot regulate their body temperature as efficiently as humans, and they can overheat extremely quickly—sometimes within minutes.

Signs Your Dog is Overheating

Watch out for these symptoms of heatstroke:

• Excessive panting or drooling
• Rapid heartbeat
• Vomiting or diarrhoea
• Weakness or collapse
• Glazed eyes or confusion

If your dog shows any of these signs, act immediately—get them into shade, offer cool (not cold) water, and seek emergency veterinary help.

Advice for Dog Owners

Here are some life-saving tips:

1. Never leave your dog in the car, even with the windows open or engine running.
2. Plan your day so your pet stays at home if you’re going somewhere dogs aren’t allowed.
3. Use dog-friendly stores or cafés that allow pets inside.
4. Carry a water bottle and portable bowl when walking in hot weather.
5. Walk your dog early in the morning or late in the evening to avoid peak heat.

What Should You Do If You See a Dog in a Hot Car?

• Call 999 immediately if you believe the dog is in danger.
• Take note of the car’s make, model, and registration.
• If it’s safe to do so and you’re waiting on police, try to locate the owner nearby.
• Only attempt to break the window as a last resort and if you believe the dog will die before help arrives—be aware this may carry legal consequences, though it can be justified to prevent suffering.

Our dogs are part of the family, and they depend on us to keep them safe. On a hot day, even a short trip can turn tragic. Don’t risk it—leave them at home, not in the heat.
