Every year, countless dogs die in hot cars on summer days. Sometimes it’s not even that hot outside. Many times the window is cracked and the car is parked in the shade.

The startling truth is that even in seemingly safe conditions the temperature inside your car can soar to life-threatening heights in just ten minutes – about the time it takes to run into the post office or the coffee shop or the pet store.

Dogs in hot cars facts

  • Even in the shade, the temperature in a car can quickly soar to dangerous levels.
  • Leaving the windows open has little effect on how hot it is inside the car.
  • Furthermore, dogs don't sweat the same way we do. Instead, they depend on panting to take in cool air and regulate their temperature. If they only have hot air to breathe, their temperature increases, putting them at risk of heat stroke.
  • That means on an 85ºF day, dogs can be at high risk of succumbing to heatstroke in less than 15 minutes. A pet parent can unknowingly do lasting harm to their four-legged friend in the time it takes them to run "a quick errand."

What to do if you see a dog trapped in a hot car

Take action! Every minute counts, so if you see a dog left in a hot car, notify a store employee to have the owner paged or call your local law enforcement agency or animal control immediately.

In the heat of the moment, you may also wonder if it is legal to break a car window to rescue a dog from a hot car. The laws on this are a bit unclear.

According to the Animal Legal Defense Fund, a majority of the states have some kind of “hot car” law, but they can vary widely in interpretation. Some states allow for law enforcement, first responders, or animal control officers to enter a vehicle, while other states have a “Good Samaritan” law that protects you from legal recourse if you take it upon yourself to free an animal from an unattended vehicle under certain circumstances.
