A dog responsible for a savage attack on a nine-year-old boy and his father in Como last month has been euthanised by the City of South Perth.
David Cooper was in his living room when he saw his next-door neighbour's dog, believed to be a Staffordshire bull terrier, jump the fence and attack his son Jai.
Mr Cooper, a qualified chef and a competitive boxer, rushed to his son's rescue and was subsequently savaged by the dog. He was saved only when Jai ran to nearby Manning Road and flagged down a passing plumber, who managed to scare the dog away with a shovel.
Mr Cooper needed major surgery to save his hand but despite his injuries he said he was sad the dog had been euthanized by the City of South Perth.
He said the living conditions of the dog were less than ideal.
"I feel sorry for the dog," he said.
"It was a big dog in a very small backyard, we live behind it in a unit so we can see everything I guess and it was just a guard dog, it never went for walks or anything like that.
"It was just too big for the space where it was kept and I do feel sorry for the dog, I didn't really want it put down but I understand that it couldn't have been rehabilitated."
"My son Jai was happy it was put down, because he doesn't really understand the situation and the dog hurt him, but me I do feel sad about it, it's not fair on the dog, the way the dog was brought up."
He said he told City of South Perth rangers to tell his neighbour not to contact him, and confirmed that he would take civil action against his neighbours.
"I don't want anything to do with them," he said.
"It's going to be two years before I get full mobility in my thumb and I've got five kids and two step-kids.
"I'm a qualified chef and I won't be able to do that for a while, and I train boxers and I can't do that, so we're struggling at the moment. I can't go back to my work until my hand and my thumb are good and that's going to be a long process.
The City of South Perth confirmed that an investigation into the attack is still underway and no conclusion had been reached on the potential prosecution of the dog's owner.
