Videos showing how quickly a car’s interior temperature rises


The following is a compilation of videos that demonstrate how quickly a car’s interior temperature (and surfaces) rise, even when it may feel “cool” outside.   Please share this page, or individual videos, with your friends and on social media, and with anyone who is in the habit of leaving their dog or child in their vehicle.

The facts about leaving dogs in hot cars by

(1) Best Friends Animal Society’s video on how quickly heat increases in a vehicle

in 2016, Best Friends produced this terrific video, which it describes as follows:

Best Friends Animal Society conducted an experiment on a 95 degree day, and discovered that the temperature inside a car – with windows down a few inches – increased from 69 to 140 degrees in 10 minutes. Never leave your pet in a parked car when the outside temperature is above 70 degrees. Even with the windows partway down, even in the shade, even for a quick errand.

Also check out the rest of Best Friends’ press release regarding the dangers to dogs in hot cars, and how to keep them cool in the summer (I’ve embedded the press release below, so you can print and share it with others).  One key takeaway point:

Never leave your pet in a parked car when the outside temperature is above 70 degrees. Not even with the windows partway down, not even in the shade, not even for a quick errand. Dogs and cats can’t sweat like humans, so they pant to lower their body temperature. If they’re inside a car, recycling very hot air, panting gives no relief, and heat stroke can happen quickly.

(2) Ernie Ward, DVM videotaped himself in a hot car

Dr. Ernie Ward is a noted veterinarian, based in North Carolina, and author of the book, “Chow Hounds: Why Our Dogs Are Getting Fatter -A Vet’s Plan to Save Their Lives.”

The following is how Dr. Ward described why he subjected himself to this situation, excerpted from HeatKills’ interview with him, here:

I had seen cases over the years of dogs having been confined in hot cars. But it was one particular incident, on a Saturday, that inspired me to do the video. I was working at the clinic, when a woman came in to pick up medicine for her dog.

We were busy, and the clock was ticking. I knew she had her dog with her, and ten minutes had passed. I expressed concern about her dog, but her response was basically, “Oh it’s okay, I left the windows partially open, and it’s only been a few minutes.”

I replied, “No, it’s been over ten minutes.” She was unaware of the danger, so I explained it to her – that even on a seemingly cool day, even with the windows partially opened, it can be dangerous or deadly to leave a dog in your car.

So a little while later, after the clinic closed down, I just decided to go film myself in a car, to show what happens to a human being when confined in such an environment.

(3) Adrian Walton, DVM videotaped himself in a hot car — twice

Adrian Walton, DVM owns the Dewdney Animal Hospital in Maple Ridge, British Columbia.  After encountering the unawareness and counter-knowledge that persists in regards to the dangers of leaving a dog in a car, Dr. Walton decided to subject himself to sitting in a car, with the windows open a few inches, for thirty minutes.  Here is the result.

Dr. Walton then produced this follow-up video, of himself in an SUV with dark tinted windows, to answer the question of whether that dynamic would help reduce the heat. The answer he discovered is quite shocking.

(4) NM police officer makes woman suffer, briefly, what she subjected her dog, by leaving it in a hot car

In April 2015, Truth or Consequences(!), NM police officer Vincent Kreischer responded to a 911 call about a dog left in a truck, in a shopping center parking lot.  Arriving on scene, he encountered the owner of the dog, Shelly Nicholas, her boyfriend and child.

During questioning, Nicholas claimed they’d only been in the store for about ten minutes, and that her dog “was fine.”

Officer Kreischer, however, determined that inside those ten minutes, the interior temperature of the truck rose to at least 114 degrees, which could easily have killed her dog.  Nicholas disputed this, claiming, “It’s not that hot.” inside her truck.

In response, Kreischer told her, “You can wait in the truck and close the door – you know, since it’s ‘not that hot.’”  So Nicholas got inside her car, with the windows up and the engine not running.

Here is the video of the encounter — after which Nicholas filed a complaint against Kerischer and the police department:

Update: In April 2015, Another police officer in Cleveland, OH, did the exact same thing, after encountering another person who left their dog in a hot car.  According to police:

To prove a point, the officer made the woman sit inside of the warm car with the windows up and without the engine on for a few minutes.

The woman said she was fine but the officer noted she looked uncomfortable. The woman was advised if she did this again she would be cited.

(5) Meteorologist Jacob Wycoff spent 30 minutes inside a hot car

In Wycoff’s words:

We hear about it all too often – a youngster or pet was left in a hot car and dies. Each year, 38 kids, on average, die of heatstroke from being left in an unattended car.

Since 1998, 581 kids have died from heatstroke, as result of being left in a car.

Over the 30 minutes I filmed this, the internal temperature of the car rose over 30º. In fact, it got so hot, my three GoPro cameras failed at separate times. I hope this video sheds light on how quick the temperature rises.

Remember, “Beat the heat, check the backseat.”

In the first experiment, the interior temperature goes from 28 degrees Celsius to 69 degrees C (156 Farenheit)
