Meet Otto of Shrewsbury, England. The lovable dachshund-terrier mix is 20 years and 8 months old — that’s about 145 in dog years — and he’s being certified as the World’s Oldest Living Dog by Guinness World Records.

Lynn Jones, 53, has owned Otto since he was six weeks old. She and her husband, Peter, contacted Guinness after the previous record-holder, Chanel — also a dachshund mix — recently died at age 21.

“He doesn’t really like walkies any more,” Lynn told The Daily Mail. “He gets about 10 yards down the road and then looks back over his shoulder as if to say, ‘I want to go home.’“
