In a surprising turn of events, Guinness World Records (GWR) has officially withdrawn the title of the “world’s oldest dog” from a Portuguese Mastiff named Bobi. This decision comes after an extensive review initiated in January raised significant doubts about the accuracy of the claims surrounding Bobi’s age. Previously celebrated as the oldest canine ever at 31 years and five months, Bobi’s record has been overshadowed by controversies and expert skepticism, prompting GWR to strip him of his title.
Investigation leads Guinness World Records to retract ‘World’s Oldest Dog’ title from Bobi, Portuguese Mastiff
GWR’s decision to investigate came after Bobi’s death in October last year, months after the Portuguese Mastiff was declared the world’s oldest living dog and oldest dog ever. Bluey, an Australian Cattle dog who passed away aged 29 years and five months in 1939, previously held this title. Various factors influenced the review process, including challenges from veterinary professionals who questioned the biological feasibility of a dog living to such an advanced age.
Critics were quick to note inconsistencies in photographic evidence from 1999, showing discrepancies in Bobi’s paw color compared to images of the dog who died. Furthermore, the registration of Bobi’s age in Portugal’s national pet database was based solely on owner certification, as pet chipping only began in 2008. While genetic tests confirmed Bobi’s senior status, they fell short of accurately verifying his claimed age — per The Guardian.
A notable investigation by Wired magazine also played a crucial role in challenging the record. Wired’s investigation into Portugal’s pet database found no definitive evidence to back the owner’s claim that Bobi was born in 1992. The owner, Leonel Costa, did not provide responses to the queries raised by the publication.
In the wake of these findings, Mark McKinley of GWR, who was instrumental in reviewing Bobi’s record, emphasized the importance of maintaining the accuracy and integrity of GWR titles. He further noted, “Following concerns raised by vets and other experts, both privately as well as within public commentary, and the findings of investigations conducted by some media outlets, we felt it important to open a review into Bobi’s record.”
