A DWARF lost in a mountain range survived overnight thanks to her chihuahua dog. Beverley Burkitt, 45, had to sleep in deep forest after losing her way on a morning walk. The 3ft 8in mum snuggled up to 7in-tall pet Pebbles — who kept her warm and saved her from hypothermia. She was found the next morning after a huge search involving Snowdonia ground teams and helicopters.
