Guinness World Record holder Bobi, a purebred Rafeiro do Alentejo, passed away at his home in Portugal on Saturday.
His death was announced on social media by a veterinarian who met Bobi several times.
“Despite outliving every dog in history, his 11,478 days on earth would never be enough, for those who loved him,” wrote Dr Karen Becker.
Bobi became both the world’s oldest living dog and the oldest dog ever in February – beating an almost century-old record for the latter title.
