A dog has been killed and its owner seriously injured in a dog attack in Perth’s northern suburbs.

Two dogs were roaming free in Dianella before lashing out at the owner and pet on an early morning walk.

The incident, just one of a spate of attacks in the area, was captured on CCTV.

The small dog was ripped from its owner’s arms and mauled by two larger dogs, on a driveway on Sycamore Rise.

The woman is seen screaming as she tries to pry her pup from their grip before a neighbour rushes over and breaks up the scuffle with a stick.

The traumatised owner suffered serious arm injures in the attack, while her beloved dog couldn’t be saved.

The pair of dogs were spotted roaming off leash about an hour before the attack, down a nearby street.

Neighbours said after the attack they kept the vicious dogs in a yard for an hour until council rangers arrived and the pair were impounded.

“It’s probably one of the most distressing bits of footage I’ve seen in my time as mayor,” City of Stirling Mayor Mark Irwin said.

“The dogs were quite obviously not under control, I’m not aware of how they got in that situation but they were not under control at the time.”

The city has around 25,000 registered dogs and attacks are something it deals with weekly.

Tonight, there’s a stern message to owners.

“People should keep their dogs under control, they should know if their dog’s reactive,” Irwin said.
