In a surprising development, the title of the world's oldest dog has been temporarily suspended by the Guinness Book of World Records amid an investigation into the true age of the canine. Bobi, a purebred Rafeiro do Alentejo from a small Portuguese town, passed away last October at the age of 31, according to owner Leonel Costa.

Bobi's remarkable age had earned him the title of the oldest dog ever and the oldest living dog, surpassing the previous record held by Bluey, an Australian cattle dog who lived to be 29 before passing away in 1939. However, suspicions were raised about the evidence supporting Bobi's age, leading to a formal review and appeals process.

Owner Leonel Costa stated that Bobi was born on May 11, 1992 when he was just 8 years old. Costa attributed Bobi's longevity to good food, fresh air, and lots of love. However, CNN reported that there were doubts surrounding the veracity of the evidence that supposedly proved Bobi's age.

In response to the investigation, the Guinness Book of World Records has decided to temporarily pause both the titles of the oldest dog living and the oldest dog ever until the findings of the review are complete. The organization typically aims to complete such investigations within three months, according to a spokesperson who spoke to WGN News.

It remains to be seen whether Bobi will be able to retain his titles or if a new contender will emerge as the rightful holder of the oldest dog record. The outcome of the investigation will shed light on the true age of this extraordinary canine and determine its place in the history books of the Guinness World Records.

For now, the suspense continues as experts dig deeper into the validity of Bobi's age, leaving the world eagerly awaiting the final findings before the title of the oldest dog can be reinstated or passed on to a new rightful holder.
