Bobi has been stripped off the world's oldest dog title

Guinness World Records (GWR) say it has no evidence that Bobi the canine, who died last October at the apparent age of 31 years and 165 days, was as old as claimed.

GWR had opened an investigation into Bobi - a Rafeiro do Alentejo from Portugal - after doubts were raised about the proof of the pooch's age.

The organisation has ruled that the microchip that was used as evidence of Bobi's old age was not sufficient proof to give him the record.

GWR said: "We're left with no conclusive evidence which can definitively prove Bobi's date of birth.

"Without any conclusive evidence available to us right now, we simply can't retain Bobi as the record holder."

GWR is yet to confirm which dog is the new record holder while Bobi's owner Leonel Costa has not commented on the removal of his late pet's title.
