A Yorkshire Terrier from Halifax called Billy could be set to claim the title of the world's oldest dog, after reaching the age of 22.

Billy may be a venerable 154 years old in dog years, is blind in one eye and only has a few teeth left - but he's still energetic and active, going out for two walks a day and regularly playing with his loving owner, 71-year-old Betty Holdsworth.
He's still able to run around and even jump - despite the fact that he was in a bad state when he was taken in by the local RSPCA before being placed with his new owner.
'His coat was filthy and matted and his nails were so long he couldn't stand up. He was also very underweight and his teeth were rotten,' the RSPCA's Jule Cockroft told the Halifax Courier earlier this month.
And bIlly could be in line to claim the record of the world's oldest dog if his age can be proved. The Guiness Book of World Records confirmed that the current holder of the title is a 21-year-old dog.
The world's previous oldest dog, a dachshund terrier cross called Otto, was put to sleep in January this year at the age of 20 years and 11 months after suffering from stomach cancer.
