Bobi, the Portuguese dog recognized by Guinness World Records as the world’s longest-living dog, has just celebrated his 31st birthday.

Bobi turns 31 on May 11 and will have a birthday party on May 20 at his owner’s home in Conqueiros, a village in southern Portugal.

Bobi’s owner, Leonel Costa, said it would be a “very traditional” Portuguese party, with more than 100 people attending and a dance company invited to perform.

According to Costa, Bobi has received a lot of attention since being declared the world’s longest-living dog by Guinness World Records in February. “A lot of journalists and people from all over the world came to take pictures with Bobi,” Costa said.

Bobi’s health is still good, but Costa recently took him for a checkup because he was worried that his dog might be stressed because of frequent contact with many people. “They took a lot of pictures so he had to stand up many times. It wasn’t easy for Bobi,” Costa added.

Bobi is a purebred Rafeiro do Alentejo, a Portuguese dog breed trained to guard livestock. Due to his age, Bobi has difficulty walking and also has impaired eyesight.

Costa believes that Bobi’s long life is partly due to the “quiet, peaceful environment” in this village. Costa was only 8 years old when his pet dog was born.

“Bobi is special because every time I look at it I remember my family members who unfortunately passed away, like my father, brother or grandparents,” Costa shared.
