LISBON, Portugal — A 31-year-old dog in Portugal that had been ranked as the world’s oldest dog ever has died, his owner said Monday.

The guard dog, called Bobi, died over the weekend in a veterinary hospital, Leonel Costa told the Associated Press.

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.

“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 aged 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.

Bobi was a purebred Rafeiro do Alentejo, a breed of Portuguese dog that has an average life expectancy of some 10 to 14 years.
