Bobi, a 31-year-old dog from Portugal, was crowned the world’s oldest living canine in Feb. 2023, but the accolade could be withdrawn. Guinness World Records placed his title on hold amid a wave of uncertainty regarding the validity of his owner’s claims. The life expectancy of a Rafeiro do Alentejo is 12 to 14 years, which means Bobi would’ve been 170 years old, per veterinary calculations. His owner, Leonal Costa, credited Bobi’s long lifespan to a diet of human food and never being chained up while speaking to GWR. However, questions arose when observers pointed out that photos of Bobi from 1999 and 2022 show the dog had different colored paws. While our review is ongoing, we have decided to temporarily pause applications on both the record titles for oldest dog living and ever until our findings are in place and have been communicated," a Guinness World Records spokesperson told the Associated Press. Bobi’s information was registered in Portugal’s government database, which GWR checked before handing out the award. WIRED reported that the information was put forth by the dog’s owner, which adds to speculation held by veterinarians. Danny Chambers of the Royal College of Veterinary Surgeons told The Guardian that “not a single one of my colleagues believes Bobi was 31." Bobi died in October 2023 and if his accolade is rescinded, the title would return to Bluey, a 29-year-old Australian cattle dog who died in 1939.
