The devastated mum of a 10-year-old boy killed in a dog attack says she is in a "living in hell" a year after his tragic death - and has called for tougher sentences.
Jack Lis was mauled to death by a seven stone XL Bully dog named Beast after going to a house to play last November.
The dog caused the lad "unsurvivable injuries" despite neighbours rushing to help.
