The Automobile Association is reminding drivers not to leave children or pets in their cars during the hot weather.
The SPCA warns that
Even with the windows slightly open, a car parked in the shade on a 30-degree day will heat up to almost 40 degrees in just 10 minutes, according to the SPCA.
It said a dog locked in a hot car could only handle temperatures of 40 degrees or more for a very short time before suffering irreparable brain damage - or even death.
AA spokesperson Dylan Thompson said in hot weather, a car could quickly get as hot as an oven, and pets or children should not be left in the car, even for a few minutes.
