Pet Age Calculator Online
Ever wondered how old your pet would be in human years? Our accurate pet age calculator converts dog, cat, and other animal ages to human equivalent years. Unlike basic calculators that use the outdated "multiply by 7" rule, our tool considers breed size, species-specific aging patterns, and developmental stages for more scientifically accurate age conversion.

Human Equivalent Age
A 1 year old medium dog is approximately 7 human years old.
Note: This conversion uses specialized formulas based on research about pet aging. For dogs and birds, size affects aging rates.
Pet Equivalent Age
A 7 year old human is approximately 1 dog years old.
Note: Human to pet conversion provides an approximate result, as the relationship isn't perfectly linear.
Did You Know?
The first year of a dog's life is equivalent to about 15 human years.
Pet Aging Facts
- Dogs - The old "multiply by 7" rule is a myth. Dogs age more rapidly in their early years, and their aging rate depends on their size.
- Cats - Cats mature quickly in their first two years (reaching the equivalent of 24 human years), then age more slowly afterward.
- Small animals - Small pets like hamsters and mice have much shorter lifespans and therefore age much more rapidly compared to humans.
- Birds - Bird aging rates vary dramatically by species, with larger birds generally living longer lives than smaller ones.
