The guard dog, called Bobi, died over the weekend in a veterinary hospital, Leonel Costa told The Associated Press.
Bobi was a purebred Rafeiro do Alentejo, a breed of Portuguese dog that has an average life expectancy of 10 to 14 years.
Bobi lived on a farm in the village of Conqueiros in Portugal with Costa and four cats. He was born on May 11, 1992, when his owner was just 8 years old.
In an interview earlier this year, Costa told the Associated Press that Bobi’s secret to a long life was good food, fresh air, and lots of love.
Dog Never Put on a Leash
“Bobi eats what we eat,” said Costa. What’s more, Bobi had never been put on a leash.
Bobi claimed the Guinness World Record from Bluey, an Australian cattle dog, who died in 1939 at age 29 and had held the record for almost a century.
Officials at the Guinness World Records on Monday said they were “saddened to learn of the death of Bobi, the world’s oldest dog ever.” In a statement on their website, they said Bobi lived to be 31 years and 165 days old and died on Saturday.
