Former LSU Tiger and current Arizona Cardinals safety Tyrann Mathieu found out just how miserable it can be to be trapped in a hot car, even for a short time.

Mathieu, in a public service announcement for People for the Ethical Treatment of Animals, sits in a vehicle for eight minutes in the Arizona heat to experience the discomfort and danger that pets often endure when left alone in a vehicle.

Mathieu reports that the temperature was 90 degrees outside the car. After a few minutes in the vehicle, Mathieu starts to visibly sweat and rub his eyes. After eight minutes, with the temperature inside the car at 120 degrees, he exits the vehicle, hunches over and immediately drinks water.

“I seriously couldn’t imagine leaving my dog in a car like this,” Mathieu says during the ordeal. “I mean, if you’re going to make a dog a part of your family, then make him a part of your family. Don’t treat him like you wouldn’t treat someone you cared about or someone you loved.”

After a injury-marred 2014 season for the Cardinals, Mathieu reported to team workouts in May feeling healthy and in good spirits. “Football is fun again,” he said.
