World’s Oldest Dog Dead at 31

Phil Stilton

Bobi, recognized as the world’s oldest living dog, died at 31 years old this week.

The dog was a purebred Rafeiro do Alentejo, a breed usually expected to live 12 to 14 years, according to owner Leonel Costa. Bobi surpassed the previous record holder, an Australian cattle-dog named Bluey, who lived from 1910 to 1939 and was 29 years and 5 months old at the time of death.

Bobi’s age was confirmed by the Veterinary Medical Service of the Municipality of Leiria, where he was registered in 1992. Further verification came from SIAC, a pet database authorized by the Portuguese government and managed by the National Union of Veterinarians.


The dog was born as one of four male puppies in an outbuilding where the Costa family stored wood. His record-breaking life span marks a significant milestone in canine longevity, considering his breed’s typical life expectancy.

This remarkable feat draws attention to advancements in veterinary care and animal husbandry, enabling dogs to live longer, healthier lives.

He spent his life in the rural village of Conqueiros, Portugal, with the Costa family.
