Dogs are the most loyal companions of human beings. They are smart, obedient and humane. However, the life span of a dog is too short compared to the life span of a human being, so no one can avoid facing the day of loss. Here is a detailed introduction to the dog with the longest lifespan in the world record. Let’s take a look with the editor!
According to the British "Daily Mail" report, a Labrador hybrid named Bella died of heart disease a few days ago. She was 30 years old and is the oldest dog in the world so far. Scientists say that comparing the equilibrium life span of dogs with that of humans, one dog year is equivalent to seven years of human life. In this calculation, this hound has lived to be 203 years old. At this age, he is not only the oldest dog in the world, but also one of the oldest animals in the world.
David Richardson is Bella's owner. He bought Bella from an RSPCA shelter 26 years ago for £70 when the dog was about 3 years old. Since then, Bella has lived with Richardson, 76, and his 81-year-old wife, Daisy Cooper. However, David Richardson did not have relevant documents to prove the dog's exact date of birth, so Bella, the world's oldest dog, could not be included in the Guinness Book of World Records. The longest-lived dog in the world currently certified by Guinness Records is a 28-year-old beagle named Butcher from Virginia, USA.
The life span of dogs is generally 9-15 years, the average life span of large dogs is 9-12 years, and the average life span of small dogs is 12-15 years. The longest is more than 20 years, but it is rare. Dogs are in their prime of life between the ages of 2 and 5. They begin to age after the age of 7 and lose their reproductive capacity around the age of 10. The human gestation period is 9 months, while the canine gestation period is only 9 weeks. Therefore, one week of a dog is equal to one month of a human, and one year is equal to 18 years of a human. Two years after birth is equivalent to 23 years old, and three years after birth is equivalent to 28 years old. After that, every year that passes increases by four years.
