Dogs that attacked Sydney jogger destroyed THREE dogs that savaged a man in Sydney's west have been destroyed, with police saying a child could not have survived the wounds they inflicted. The American Staffordshire terriers attacked the 49-year-old man as he was jogging in Ashcroft about 2pm (AEST) on Sunday and caused serious injuries to his arms. The man is in a stable condition in Liverpool Hospital, a hospital spokeswoman said on Monday evening. Liverpool Council said the dogs had been put down. "The three dogs ... were voluntarily surrendered for destruction by the owner," the council's general manager, Farooq Portelli, said in a statement. The dogs were euthanised today at council's pound facility. Earlier, Liverpool Council said the dogs' owner had previously been fined for failing to have the animals registered. Police believe the dogs had escaped into the street through a hole in a fence. Detective Superintendent Jim Johnson told reporters the dogs' owner was in shock when he came to the police station. He said the owner would probably be charged with keeping a savage dog, which can attract a fine of up to $5500. "If a child or young person had been attacked, I have doubt whatever that that child would suffered fatal injuries," he added. The people who helped the man being attacked will be recommended for bravery awards, Supt Johnson said. The NSW opposition has called for an investigation into Sunday's attack and for tougher laws, including stricter reporting requirements for owners of dangerous animals.
