This dog won’t bite the dust!

The world’s oldest pooch turned 31 years old Thursday and will celebrate the milestone with a bone-ified birthday bash in Portugal,  his owner said.

Bobi — a purebred Rafeiro do Alentejo born May 11, 1992 — was named “oldest living dog” by Guinness World Records and is also the oldest canine ever recorded.

The good old boy will host 100 fans and friends, including folks from other countries, for a howling good time at his birthday party in the village of Conqueiros Saturday, said his owner Leonel Costa, 38.

“Looking at him is like remembering the people who were part of our family and unfortunately are no longer here, like my father, my brother or my grandparents who have already left this world,” Costa told Guinness. “Bobi represents those generations.”

The senior sniffer comes from a line of long-living pooches, including his mom, Gira, who lived to the ripe old age of 18.

In February, he dethroned an Ohio Chihuahua named Spike to claim the oldest dog title.

Bobi’s birth date was confirmed by the Veterinary Medical Service of the Municipality of Leiria along with the government-run pet database SIAC.

Rafeiro do Alentejos are a breed of livestock watchdogs with an average lifespan of 12 years old.
