Gabriel Swan's skull exposed in dog attack at Chipping Norton home A dog has mauled a young boy in southwest Sydney and left him with extensive facial injuries. A FOUR-YEAR-OLD boy was last night recovering in hospital from horrific facial injuries after he was savaged by a neighbour's bull-mastiff. Gabriel Swan underwent emergency surgery for a deep bite that exposed his skull. Shocked relatives, who feared the worst when they saw Gabriel lying in a pool of blood, said the youngster loved playing with the dog, named Bully.

" (Bully) would never harm anyone, or so we thought," Gabriel's older brother Sheighdon Hayes, 18, said yesterday.

Police seized the dog, which remained in a pound while its owner was being contacted. Sergeant Greg Tidyman, the duty officer of Liverpool Police Station, said it was most likely a decision would be made within days to have Bully put down. He said Gabriel was lucky to have avoided any life-threatening injuries, which was most likely sparked because the dog was tired of playing with the youngster. "They've (cared for the dog) hundreds of times before and there's never been an issue," Sgt Tidyman said. They're shocked, given the dog's been there many times and they've never had problems with it in the past.
