Bobi, the world's oldest dog, celebrated his 31st birthday on the farm where he lives in Conqueiros, Portugal. His family threw a "very traditional" Portuguese party with more than 100 guests. His owner, Lionel Costa, said that people traveled from all over the world to get a picture with the pup. The Guinness Book of World Records declared Bobi the oldest dog in the world back in February 2023, which Costa said contributed to the party's popularity.

Bobi has seen quite a number of weather events over his long life. At 11, which is actually pretty old for that breed that has an average lifespan of 12 to 14 years, he lived through a European heat wave that killed 2,100 people in Portugal and saw temperatures skyrocket to 117 degrees. He was 25 years old when wildfires devastated central Portugal in June 2017.

His family attributed his super long life to the “calm, peaceful environment” Bobi lives in, “far from the cities.” They say he has always roamed free on the farm and enjoys the company of many of the other animals that live there.

Now that he's well into his geriatric years, he has slowed down quite a bit and lost some of his sight. Most of the time, he can be found lying around in the backyard or sitting by the fire on colder days.

His family keeps up with vet visits and told Guinness that “the exams have always shown that he is doing well for his advanced age.”

They added, “Bobi is special because looking at him is like remembering the people who were part of our family and unfortunately are no longer here, like my father, my brother, or my grandparents who have already left this world. Bobi represents those generations.”

Guinness confirmed his age through the Portuguese government’s pet database.
