Guinness World Records Revokes Title of World's Oldest Dog

Bobi's title as the world's oldest dog has been posthumously removed due to insufficient evidence, prompting Guinness World Records to update its criteria for pet age verification.

Bobi, a Rafeiro do Alentejo from Portugal, has been posthumously stripped of his Guinness World Record title as the world's oldest dog due to insufficient evidence of his age.
The investigation by Guinness World Records was prompted by doubts over the reliability of the microchip data and veterinary statements used to prove Bobi's age.
Guinness World Records has amended its criteria for oldest pet records to require documentation for every year of an animal's life.
Scientists are analyzing samples from Bobi to learn more about his age and the factors contributing to his long lifespan.
Guinness World Records has not yet determined a new record holder for the world's oldest dog.
