Bobi, Portuguese Rafeiro do Alentejo, oldest recorded dog (died 2023)

Bobi was a male purebred Rafeiro do Alentejo dog cared for by Leonel Costa of Conqueiros, Leiria, Portugal. Bobi was claimed by his caretaker to be the oldest dog to ever live and the first dog on record to reach 30 years. On 2 February 2023, Bobi was certified by Guinness World Records as the oldest living dog, along with being the oldest dog on record to ever live. However, after veterinarians became suspicious of his real age, an investigation was pursued. Once his records were revoked, he was stripped of the title. Bobi died on 21 October 2023, reportedly aged 31 years and 163 days.

The Rafeiro do Alentejo or Rafeiro Alentejano is a Portuguese breed of flock guardian dog. It is named for its area of origin, the Alentejo region of southern Portugal. It is recognised by the Clube Português de Canicultura, and was definitively accepted by the Fédération Cynologique Internationale in 1954.
