💡 Understanding Your Pet's Human Age

1. Is it true that 1 dog year equals 7 human years?

No. The "multiply by 7" rule is an oversimplification. This calculator uses a project-defined non-linear educational model in which dogs and cats mature quickly during their first two years. It is not an official AVMA conversion or a veterinary assessment.

2. How is the calculation actually done?

It's based on breed size and species:

  • First Two Years: Both dogs and cats age very quickly. A 1-year-old pet is about 15 in human years, and a 2-year-old is roughly 24.
  • Dog Age to Human Years (After Age 2): It depends on size. Small dogs add about 4 human years per calendar year, medium dogs add 5, and large dogs add 6 to 7.
  • Cat Age to Human Years (After Age 2): Cats generally add about 4 human years per calendar year, similar to a small dog. (This assumes an indoor cat).
3. Does size really affect a dog's lifespan?

Size can be associated with different aging patterns and lifespans in dogs. The Small, Medium, and Large choices only select broad rates in this educational model; they do not make the result a precise forecast for an individual dog.
