Synopsis: Easy to read table and calculator shows the equivalent dogs age compared to a humans age in years, includes average dog life expectancy in years by breed. The previous formula that had been used for many years was based on the calculation that 1 dog year equaled approximately 7 human years. The official holder of the world's oldest dog is held by an Australian Cattle Dog named Bluey who died in 1939 at age 29.
Main Digest
No one formula for dog-to-human age conversion is scientifically agreed on. A 2019 study suggests a new formula based on changes made to a dogs' DNA over time. The previous formula that had been used for many years was based on the calculation that 1 dog year equaled approximately 7 human years. Today, as a general rule, the American Veterinary Medical Association states:
- The first year of a medium-sized dog equals around 15 human years.
- The second year of a dog equates to approximately nine human years - which makes a 2 year old dog equal to a 24 year old human (15+9=24).
- After that every human year equals approximately five dog years.
World's Oldest Dog
The official holder of the world's oldest dog is held by an Australian Blue Heeler cattle dog named Bluey who died in 1939 at age 29. Guinness World Records says he was bought as a puppy in 1910 in Victoria, Australia, and worked among cattle and sheep for nearly 20 years before eventually being put to sleep.
Average Age for a Dog
The average age at death for dogs - all breeds, all causes - was 11 years and 1 month, but in dogs dying of natural causes it was 12 years and 8 months. Only 8% of dogs lived beyond 15, and 64%of dogs died of disease or were euthanized as a result of disease - (wikipedia.org/wiki/Aging_in_dogs).
