(Radio Iowa) – Forecasters say many Iowa cities will see high temperatures reach 100-degrees today (Thursday) and that heat will be tough on people — and pets. K-C Routos, at the Animal Rescue League of Iowa, says despite all of the warnings, some pet owners will still leave their animals locked in the car with a window cracked as they run an errand. It could be a deadly mistake as the inside temperature can quickly rise to lethal levels.

Routos says it’s best just to leave your pet at home when it’s this hot. On that topic, if your dog or cat is staying home in this heat, make certain they have access to water, and don’t leave them fenced in or chained up outdoors — inside is best. Many dogs love to go on walks, but during a heat wave, it’s wise to limit their time outdoors, perhaps just to walks in the morning and evening when it’s cooler.
