Guinness World Records (GWR) is investigating the title of the “world’s oldest dog” awarded to a Portuguese dog named Bobi, who passed away last year. Veterinarians raised concerns about the accuracy of Bobi’s reported age. Bobi, a purebred Rafeiro Alentejano, initially declared the world’s oldest dog by GWR, lived an impressive 31 years and 165 days, surpassing a record set in 1939 by an Australian cattle dog. Bobi earned this title in February but sadly passed away in October of the same year. Bobi’s breed typically lives 12–14 years. GWR is conducting a comprehensive review, examining evidence, seeking new information, and consulting experts. Applications for both the “oldest dog living” and “oldest dog ever” titles are temporarily suspended. Bobi’s owner, Leonel Costa, is disappointed that GWR has not contacted him. Some veterinarians disputed Bobi’s age, attributing it to a diet of “human food.” GWR clarified that no action is taken against record holders pending the review’s outcome. Before Bobi’s demise, he enjoyed walks but became less adventurous, with thinning fur, deteriorating eyesight, and a need for more rest compared to his earlier years.
