Source-derived summary

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.

Editorial analysis

Why this record matters

“Bobi (dog)” is worth following because a concise public description often conceals a longer documentary argument. Here, Bobi, Revoked and Guinness provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 24, 2026. The first chronological checks are 2023.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
