Bobi world's oldest dog breed

In February, a Portuguese dog named Bobi made history as the oldest canine ever, and now he’s celebrating his 31st birthday. Yes, you read that right: thirty-one. Bobi’s age and status as the world’s oldest dog is legit as confirmed by Guinness World Records. The senior pup’s birthday festivities are set to take place in the quiet rural village of Conqueiros in Leiria, western Portugal.

Bobi was born on May 11, 1992, which means he is 31 in human years. The general rule of thumb is one dog year equals seven human years. So, if Bobi was a person, he would be an astounding 217 years old. Read to find out what breed is Bobi and the world’s oldest dog’s secret to a long life. 

Identifying the breed of Bobi, the world’s oldest dog

The world’s oldest dog Bobi is a remarkable purebred Rafeiro do Alentejo. Mostly found in Portugal, this breed has a long history as both hunting and guardian dogs. They are known for their strength and confidence. 

Despite their purebred status, some Rafeiro do Alentejo dogs end up in shelters or rescues. Other common names for them include Portuguese Watchdogs or Alentejo Mastiffs.

Back in 1992, the Costa family, Bobi’s owners, discovered him as a newborn puppy in their wood storage shed. Leonel Costa, now 38, was only eight years old at the time. Initially, the family intended to bury Bobi and his three brothers, but Leonel’s father had a change of heart, allowing Bobi to thrive.

Who was the world’s oldest dog before Bobi?

Previously, the title belonged to Spike, a 23-year-old Chihuahua from Ohio, USA. However, Bobi’s age of 31 in human years has earned him the recognition as the oldest dog ever recorded.

This means he surpassed the previous record held by Bluey, an Australian cattle dog who lived to be 29 years and five months old before passing away in 1939.

While dogs typically live for 10 to 13 human years, Bobi’s age has been confirmed by his veterinarian and a government-authorized pet database in Portugal.

However, as he has entered his old age, Bobi’s eyesight has deteriorated, causing him to spend more time near his dwelling, keeping company with the family’s cats in the backyard. 

What is the secret to Bobi’s long life?

Bobi’s mother, Gira, lived until the age of 18, which is a respectable lifespan as well. Instead of consuming commercial dog food, Bobi has always been fed the same meals as his human owners, albeit without any seasonings, by soaking the food in water. His daily water intake amounts to approximately one liter, as reported by his owners.

According to Guinness World Records, Leonel attributes Bobi’s remarkable long life to the peaceful environment in which he resides, far away from urban areas. Throughout his life, Bobi has never been restrained by chains or leashes; he has enjoyed the freedom to wander the forests and farmland surrounding the Costa family’s home.
