Bobi (Portuguese pronunciation: [buˈβi], 11 May 1992[a] – 21 October 2023) was a male purebred Rafeiro do Alentejo dog owned by Leonel Costa of Conqueiros, Leiria, Portugal.

[7] This surpassed the previous record held by Bluey, a female Australian Cattle Dog, who was euthanized on 14 November 1939 at the age of 29 years and 5 months.

[8] On 7 December 2022, in the U.S. state of Ohio, a 23-year-old chihuahua named Spike was certified as the oldest living dog; however, that title was short-lived as Bobi's age was verified two weeks later.

[10] On 29 October 2023, Guinness World Records announced it would re-investigate Bobi's age to address veterinarian questions and concerns over the lack of evidence freely available to the public.

It also was speculated that the photographs shared of Bobi at a young age were of a different dog due to its markings, but this has never been completely confirmed.
