Why People Leave Dogs in Cars
People often leave dogs in the car for short times. Maybe to shop, eat, or run errands. Sometimes, it feels like the dog will be okay for a few minutes. But even short times can be risky.
What Happens Inside a Parked Car?
When a car is parked, the inside can heat up fast. Even if the weather is cool outside, the car can become very hot inside. The sun shines through windows and traps heat. This is called the greenhouse effect.
In just 10 minutes, a car can become too hot for a dog. Dogs cannot cool down like people. They mostly cool by panting. When it is hot, dogs can get heatstroke.
What is Heatstroke?
Heatstroke is when a dog’s body gets too hot. It can cause:
- Heavy panting
- Drooling
- Weakness or collapse
- Seizures
- Death in severe cases
Heatstroke is an emergency. Dogs need help right away if this happens.
Which Dogs are at Higher Risk?
Some dogs are more likely to get heatstroke. These include:
- Dogs with thick fur, like Huskies or Malamutes
- Brachycephalic breeds (short noses), like Bulldogs, Pugs, and Boxers
- Old or sick dogs who cannot handle heat well
- Very young puppies who are still small and weak
How Long Can You Leave a Dog in the Car?
The answer is simple: It is best not to leave your dog alone in a car at all.
