Dogs are loyal friends of man and their owners want them to live longer. The average life expectancy of a four-legged friend is about 13 years, but it all depends on the breed of dog, health and living conditions.

The Guinness Book of World Records has a record-breaking dog that is already 31 years old. This is the oldest dog in the history of mankind.

The dog named Bobi lives in Portugal. He was born on May 11, 1992 and has three other siblings. In February 2023, he entered the Guinness Book of World Records as the oldest dog.

Bobi is a purebred Rafeiro do Alentejo. It is a Portuguese dog breed that lives an average of 12 to 14 years.

The previous oldest dog was an Australian Bluey, who was born in 1910 and died at the age of 29 years and 5 months.

OBOZREVATEL also published the opinion of scientists on the life expectancy of pets. Scientists have identified five key factors of the social environment of the dog, including the well-being of the neighborhood, family income, the time of communication with children and other animals and the age of the owner.

One of the key factors affecting a pet's longevity is the opportunity to socialize with other dogs.

Pet health was also better in families with no children or with one or two only.
