A five-year-old boy has undergone extensive plastic surgery after his ear was bitten off when his neighbour's dog viciously mauled him a day before his birthday. Kellen Cormie's ear was bitten off in the attack outside his Gold Coast home on Saturday and he suffered puncture wounds to his shoulder and abdomen where the dog latched on. The large blue staffy that savaged the little boy was put down on Monday afternoon after its owners surrendered it to Gold Coast City Council.
