Grand Teton National Park Issues Urgent Pet Safety PSA: Don’t Leave Pets in Hot Cars
Grand Teton National Park has issued a critical public service announcement (PSA) urging visitors to prioritize pet safety by not leaving pets in locked vehicles during hot summer days. This caution is essential for dogs as hot cars can be perilous for them. This warning comes after park rangers responded to multiple emergency calls regarding pets in distress, highlighting the dangers of heatstroke in vehicles, even at high elevations.
Why Pet Safety in Hot Cars Matters
Leaving pets in cars during warm weather can lead to deadly consequences. According to the National Park Service, even with windows partially open, the interior of a vehicle can reach life-threatening temperatures in minutes. At Grand Teton National Park, located in Wyoming, the high elevation amplifies the sun’s intensity, making the risk even greater. In particular, dogs in hot cars are at a high risk:
Key Facts About Heat Risks at Grand Teton:
- Elevation Impact: The park’s elevation ranges from 6,320 feet to 13,770 feet, increasing the sun’s intensity by up to 39%—6.5 times stronger than at sea level.
- Rapid Temperature Rise: On a 70°F day, a car’s interior can exceed 115°F within an hour, even with cracked windows.
- Heatstroke Danger: Dogs are highly susceptible to heatstroke, especially when trapped in cars, which can cause organ damage or, in extreme cases, death in as little as 15–30 minutes.

The park’s PSA humorously noted, “The only hot dogs we like are the kind sizzling on a grill. Glizzy anyone?” This lighthearted tone underscores a serious message: pet safety is a shared responsibility.
