Temperatures are expected into the 90s Monday and Tuesday, so the Massachusetts State Police is reminding people about the dangers of leaving pets in hot cars.

Police say even with the windows open, pets could die, because on a 90-degree day, temperatures inside a car can reach 109-degrees in just 10 minutes and get to 135 degrees within an hour. Cummings School of Veterinary Medicine at Tufts University Professor Michael Stone advises to never leave a dog alone in a hot car. He also says it’s important to keep pets cool and hydrated when outside.

"You've got to be careful especially with abrupt heat. Now when it's hot outside we also have to be careful about keeping plenty of water available for pets, making sure they have water at all times. Allowing them to have a shady place to be so that they are not just stuck in the sun all day especially if they are chained up outside,” Stone said.

State Police add if you see a dog in a hot car and the situation is dire, laws allow you to make entry as long as you have tried to locate the owner and have called the police.
