Too many dogs have been left in hot cars, with the RSPCA responding to 39 reports in the past two weeks.
Just yesterday, a puppy was rescued from a car in Bullcreek, after concerned shoppers noticed the pup inside for around an hour.
Only last month, a mastiff was pulled out of a hot car in Balga, but sadly, it couldn't be saved.
As the temperature climbs to 36 degrees today, the RSCPA is encouraging anyone who sees a dog left in a car to call inspectors immediately on 9209 9300.
The advice is to remain calm, and avoid standing too close to the car because that can distress the animal further.
