One lucky dog

Bobi was a lucky dog.

He was born in a litter of four puppies, according to Guinness, but because his owners family already owned too many animals, his father decided not to keep them.

“Unfortunately, at that time it was considered normal by older people... to bury the animals in a hole so that they would not survive,” Costa told Guinness.

Costa parents, Guinness reported, took the litter away but he and his brothers found Bobi, who had escaped, hiding in a pile of wood at their home.

The siblings kept the puppy’s existence a secret but when the boys' parents discovered Bobi was alive, Guiness reported, "it was too late to put him down, so Bobi became a part of the family."

A life of love and celebration

Bobi lived a life full of love and celebration.

His owner was only 8 years old when Bobi was born.

Just this past May, his owner threw him a lavish birthday party with more than 100 guests attending to celebrate him turning 31.

When he turned 30 last year, his owner described Bobi as "one of a kind" – adding that the family is "very happy and grateful to life for allowing us, after 30 years, to have Bobi in our daily lives."

Bobi's death was announced by Veterinarian Karen Becker on Facebook, who posted, "Last night, this sweet boy earned his wings.'

"Despite outliving every dog in history, his 11,478 days on earth would never be enough, for those who loved him," Guinness reported in an article posted on its homepage. "Godspeed, Bobi…you’ve taught the world all you were meant to teach."

RIP, Bobi.
