World's oldest dog' title thrown into doubt

A Portuguese dog named Bobi made headlines last year when he was crowned the world's oldest dog ever by Guinness World Records (GWR) - beating a previous record that stood for a century.

Bobi died in October at the official age of 31 years and 165 days.

But now his title has been thrown into doubt, after some veterinarians questioned evidence of Bobi's age.

GWR have now suspended the title and launched an investigation.

Bobi was a purebred Rafeiro do Alentejo - a breed that has an average life expectancy of 12 to 14 (human) years.

His grand old age was validated by the Portuguese government's pet database, which is managed by the National Union of Veterinarians, GWR said last year.

But as news of his crowning rapidly spread - so too did suspicion.

An investigation by Wired magazine found that Bobi had been registered on Portugal's pet database as having been born in 1992, but it had "no registration or data that can confirm or deny this statement".

There were also questions over old photos of the pet that showed different markings on his fur, with some suggesting it was a different dog altogether.

Among experts, there has been growing scepticism.

Danny Chambers, a member of the Royal College of Veterinary Surgeons, told The Guardian: "Not a single one of my veterinary colleagues believe Bobi was actually 31 years old."

Now, Guinness World Records have launched a formal investigation.

"While our review is ongoing, we have decided to temporarily pause applications on both the record titles for oldest dog living and (oldest dog) ever until all of our findings are in place and have been communicated," a spokesperson told the AFP news agency.

Bobi lived his whole life with the Costa family in the village of Conqueiros, near Portugal's west coast.

His owner, Leonel Costa, said in a statement that "an elite within the veterinary world... tried to give people the idea that Bobi's life story was not true".

Mr Costa believes the backlash came because he attributed Bobi's longevity to eating a diet similar to that of humans, rather than pet food. He says this goes against the recommendations of many veterinarians.

"Everything would be different if we had said he ate pet food for three decades," Mr Costa said, adding that everything GWR had requested to validate Bobi's age had been met.

Until Bobi's death, the previous oldest dog ever was Australia's Bluey, who died in 1939 at the age of 29.

how did he live so long?

According to veterinarian Dr. Karen Becker, the owner of Bobi, the world’s oldest dog, revealed that the dog had access to the best nutrition and was in touch with nature for most of the time. The dog was additionally getting the best veterinary care. Fresh human food was the dog’s main diet. Bobi lived with Leonel Costa at a Portugal-based farm. The pet belonged to the Rafeiro do Alentejo breed, which can reportedly survive up to 12 or 14 years, as per the American Kennel Club. The dog was never tied to a leash or chain and lived in a peaceful environment, which helped his survival over the years. Bobi’s longevity was attributed to a tranquil lifestyle, far removed from the bustling city. Unchained and unrestricted by leashes, Bobi reveled in the freedom of the forests and fields surrounding the Costa family home. Growing up alongside a host of other animals, his sociable nature likely played a role in his long and vibrant life

It is worth noting that Bobi’s longevity is not scientifically proven, and his age was disputed by Guinness World Records
