In 2023, Bobi became a global sensation after Guinness World Records recognized him as both the world’s oldest living dog and the oldest dog ever recorded. According to his reported birth date of 11 May 1992, Bobi lived an astonishing 31 years and 165 days, passing away on 20 October 2023. If accurate, he would have shattered the previous longevity record by several years, making him one of the most extraordinary dogs in history.

Bobi was a Rafeiro do Alentejo, a large Portuguese livestock guardian breed whose average lifespan is typically 10 to 14 years. His owner, Leonel Costa, attributed the dog’s exceptional longevity to a calm countryside life, unrestricted movement, fresh food, and a stress-free environment. News of Bobi’s remarkable age spread around the world, inspiring millions and earning widespread media attention.

However, the story took an unexpected turn in early 2024. Veterinarians, researchers, and other experts raised questions about the evidence supporting Bobi’s reported age, pointing to inconsistencies in the available records and the lack of definitive historical documentation. After conducting a review, Guinness World Records suspended Bobi’s titles, stating that it did not have sufficient evidence to confidently verify his exact age. As a result, the organization no longer recognizes him as either the oldest living dog or the oldest dog ever.
