A horrified mother discovered the body of her ten-year-old daughter who had been mauled to death by the family's XL Bully dog, which was ‘covered in blood’, an inquest heard today. Tracey Bentham had left her daughter Savannah watching television with the dog, named Biggie, in their static caravan home. He said the family had owned the XL Bully for four years. Savannah Bentham died after being attacked by the family XL Bully, named Biggie (file photo)'So Tracey went to find [grandfather] Mark to sort out the connection. I find Biggie was an XL Bully and registered in accordance with an an XL Bully exemption certificate.
