WATCH: Lonnie Walker IV shows the dangers of leaving dogs in a hot car

San Antonio Spurs' Lonnie Walker IV is not only making an impact on the court but off as well.

Walker recently helped out PETA in an effort to get the word out about the danger of leaving dogs in hot cars.

And the Spurs guard went above and beyond to make a point by trapping himself in a car.

"We'll be quick!" That's what a friend says to Lonnie Walker before leaving with the San Antonio Spurs star's beloved dog, Zola, in a new PETA video that puts the athlete in the place of the many animals who suffer from heatstroke and die after being left in hot cars every summer.

In the back seat of the car, Walker sweats, gasps for air, and grows dizzy as the vehicle's interior temperature reaches 109 degrees in just 20 minutes—and as the video points out, since dogs can't sweat from most of their bodies and primarily cool themselves by panting, they're at greater risk of suffering from heatstroke than humans are.

"If you see a dog alone in a hot car, take down the car's information and contact the dog's guardians," Walker urges in the video. "Or just call the authorities. You could save a life."

PETA—whose motto reads, in part, that "animals are not ours to abuse in any way"—urges people who spot a dog in a hot vehicle to remain at the scene until the situation has been resolved. If the authorities are unresponsive or too slow and the dog's life appears to be in imminent danger, find a witness (or several) who will back up your assessment. Then remove the suffering animal from the car and wait for authorities to arrive. PETA offers an emergency window-breaking hammer for help intervening in these life-or-death situations.

Walker joins a long list of athletes—including Tyrann Mathieu, Chris Harris Jr., Alex Morgan, Christen Press, Metta World Peace, Ty Lawson, and Candace Parker—who've teamed up with PETA to promote kindness to animals.
