World’s oldest dog is celebrating his birthday with a 'very traditional' Portuguese party

In February, a Portuguese pup smashed the record for the oldest dog ever. Now, he's celebrating his 31st birthday.

A big birthday party is planned for Bobi today, according to Guinness World Records. 

It will take place at his home in the rural Portuguese village of Conqueiros in Leiria, western Portugal, where he has lived his entire life.

Bobi is a purebred Rafeiro do Alentejo, a Portuguese breed of livestock guardian dog.

Bobi was born on 11 May 1992, making him 31 years old, in human years.

He has smashed the record for the oldest living dog, who, until recently, was thought to be 23-year-old Spike, a chihuahua living in Ohio, USA.

Spike was awarded the title just two weeks ago. Then, Guinness World Records received evidence of the much older Bobi, who not only stole Spike’s title but earned recognition as the oldest dog ever.

The previous record was held by Bluey, an Australian cattle dog who died in 1939 at the age of 29 years and five months.

Dogs typically only live for 10 to 13 human years. The world's oldest cat is 26 years old.

Bobi’s age has been verified by his vet and a pet database authorised by the Portuguese government.

Bobi has been owned by the Costa family since he was born in an outhouse where they stored wood in 1992.

One of his owners Leonel Costa, now aged 38, was eight at the time.

His father decided that they could not keep Bobi and his three brothers, and planned to bury them so they would not survive.

When Leonel’s father took the puppies to their sad fate, he didn’t realise he had left one behind. It was only when they noticed the puppies’ mother, Gira, kept returning to the outbuilding that they realised one had evaded Leonel’s father.

Leonel and his brothers decided to keep Bobi as their secret, knowing
