Summer is a wonderful time for outdoor adventures with your dog, but it also brings certain risks that every pet owner should be aware of. One of the greatest dangers during the warmer months is leaving a dog in a parked car. It may seem harmless to leave your dog alone while you quickly pop into a shop, but even a few minutes can have devastating consequences.
In this blog, we explain why you should never leave your dog in a car during hot weather and share important facts about how quickly temperatures inside a vehicle can rise.
5 Reasons Why You Should Never Leave Your Dog in a Car During Hot Weather
1. Heat and Heat-Related Illnesses
Dogs cannot cool themselves as efficiently as humans. While people sweat through glands across most of their bodies, dogs mainly regulate their body temperature by panting and through the pads of their paws. This makes it much harder for them to cope with extreme heat.
When a dog is left inside a parked car, the temperature rises incredibly quickly—even on relatively mild days. Within just a few minutes, the inside of the vehicle can reach dangerous temperatures, putting your dog at risk of heat exhaustion, heatstroke, organ failure and, in the worst cases, death.
2. Temperatures Rise Faster Than You Think
Many people underestimate how quickly a parked car heats up.
Research has shown that the temperature inside a car can increase by as much as 10°C (18°F) in just 10 minutes. After 30 minutes, it may be 20°C (36°F) hotter than the outside temperature.
That means if it's only 25°C (77°F) outside, the temperature inside your car could quickly reach 45°C (113°F)—hot enough to become life-threatening for your dog.
3. The Dangers of Overheating
Dogs can overheat very quickly, and the consequences can be severe.
Signs of overheating include:
- Excessive panting
- Heavy drooling
- Weakness or lethargy
- Vomiting
- Diarrhoea
- Collapse
In severe cases, overheating can lead to heatstroke, organ failure and can even be fatal.
If you think your dog may be suffering from heatstroke, contact our veterinary clinic in Leende or Heeze immediately. Acting quickly can make all the difference.
4. Open Windows and Shade Are Not Enough
Some people believe that parking in the shade or leaving a window slightly open will keep their dog safe. Unfortunately, this is a dangerous misconception.
Even with the windows cracked open or the vehicle parked in the shade, the temperature inside a car can still rise rapidly to dangerous levels. These measures simply do not provide enough protection.
Never leave your dog unattended in a parked car, regardless of the weather conditions or how short your errand may be.
5. Protect Your Best Friend
Your dog is a loyal companion and deserves the very best care, especially during periods of warm weather.
Always make sure your dog has access to a cool, safe environment with plenty of fresh drinking water. If you plan to take your dog with you on a trip, never leave them alone in the car—not even for a few minutes.

No Dog Should Ever Be Left in a Car During Hot Weather
Leaving your dog in a parked car during warm weather can have tragic consequences. Understanding the risks of heat-related illnesses and how quickly temperatures rise inside a vehicle can help save your pet's life.
Protect your four-legged friend by ensuring they are never left unattended in a parked car. Keep your pet safe, healthy and happy throughout the summer by enjoying cooler activities together and providing plenty of shade, fresh water and opportunities to rest.
