Convert your dog or cat's age to human years and get age-appropriate care recommendations.
The traditional "multiply by 7" rule is a myth. Dogs age faster in their early years, with the first year equivalent to about 15 human years. Size also plays a crucial role - smaller dogs generally live longer and age more slowly than larger breeds.
Cats age rapidly in their first two years of life. The first year equals about 15 human years, while the second year adds 9 more years. After that, each cat year equals about 4 human years. Indoor cats typically live longer than outdoor cats.
