A partially-sighted walker who was rescued after spending 20 hours badly injured on a freezing mountain on Christmas Day, praised his dog for remaining at his side.

Jonathon Harrington from Brecon, south Wales suffered spine and head injuries when he fell down a gully in Wales, taking his 15-year-old-sheepdog Prince with him.

Ten minutes before the accident Mr Harrington, 47, called rescue services from his mobile telephone to say he was lost on Cader Idris and needed advice But he carried on walking and plunged down the gully.

Prince guarded him but he was in despair when he thought the rescue had been called off. Rescuers eventually found him on Boxing Day.

Praising his dog, Mr Harrington said: ‘He cuddled up to me and stood guard. He was very cold but he was more concerned for me. He was beside me when the rescuers arrived.’
