If dogs were to extend their stay, what would be the impact on humans if they did not depart from us? Well for Leonel Costa, from Central Portugal.

This is very much a reality. His dog, Bobi, was born 3 decades ago, becoming the longest living dog in the present day.

Costa got in touch with the Guinness World of Records and submitted all the paperwork. a purebred Rafeiro do Alentejo, celebrated his 30th birthday last year.  

A year later Bobi was officially named the oldest dog on record. Bobi was 30 years and 269 days old as of Feb. 4.

Life expectancy (12-15 years) Bobi's breed usually has a life expectancy of 12 to 15 years and Costa attributed its longevity to a number of factors.

Including living in calm countryside, never having been chained or kept on a leash and always eating human food.

Later he has trouble walking and worsening eyesight; Costa described him as the “last of a long generation of animals” in the family and called him one of a kind.

Previous record breaker was held by an Australian dog named Bluey, who died in 1939 aged 29 years and five months.
