The owner of a dog pulled from a hot car in Perth has sobbed as he apologised for the pet’s tragic death.

Steve says he left his dog Bully in his car as he went to lodge a rental application.

He told 7 News he had no other choice as he’s been living in his car since losing his job, his home and his teenage son to illness.

“To the public out there, I’m sorry,” he said, breaking down in tears.

“I didn’t mean for this. I really didn’t. I’m sorry.

“If I could take it all back I would.

“I made one simple error … My intentions wasn’t to kill my dog.”

Steve’s dog Bully, a male mastiff, was trapped for two hours in the Holden Astra parked on Fletching Street in Balga on Wednesday afternoon. The temperature outside reached 27C, but the RSPCA says it could have easily been 50C inside the car.

Confronting video has been released of the moment passers by saw Bully in the car and tried to set him free.

Nicci, a trainee vet nurse, gave Bully CPR with a neighbour.

“He was doing the compressions and I was doing the breathes,” she said.

“But he was such a big dog, I just didn’t have the lung capacity to even really do much, but I tried.”

The RSPCA says Steve has no excuse for Bully’s tragic death.

“Stop making your stupid excuses,” spokesperson Amanda Swift said.

“Stop putting your animals at risk.

“This is neglect. It is cruelty and you can face prosecution.”
