Another two dogs have been left locked in cars on a hot Perth day.

Anger erupted on social media today after dogs were seen in separate vehicles in Fremantle just days after The West Australian reported a mixed Staffordshire cross was left distressed in a car in Harrisdale.

Onlooker Elisabeth posted on popular Facebook group Freo Massive a photo of a dog in a red Toyota SUV in Point Street, Fremantle, after 2pm Wednesday.

The maximum temperature hit 35.7C less than an hour later.

“How do you report something like this, will it even be taken seriously,” she wrote.

“Fremantle rangers called, they came and waited with the dog as the ticket on her car was expiring soon after they arrived. She was let off with a warning.”

Group members advised Elisabeth to “smash the window” while some said to “leave the dog alone” as one of the windows was left down “sufficiently”.

In a second report, a Freo Massive member said a dog was seen locked in a car in South Fremantle for more than 30 minutes while the owner was shopping.

“I can’t even see a window down, shame on the owner,” one member commented.

Facebook group Western Australian Lost Pet Register shared the post about the dog in Fremantle.

“When will people learn,” Lynda wrote.

The RSPCA has previously said leaving windows down makes little difference to the temperature inside the car and advises people to leave their dogs at home on very hot days.

If a dog is found to be harmed from being left in a vehicle, its owner will face a maximum fine of $50,000 or five years’ jail.
