How Puppy Age Conversion Works
Puppies age much faster than humans during their first two years. In general, the first year of a dog's life is roughly equal to 10.5 human years. After age two, each additional dog year is estimated as about four human years.
This calculator gives a quick estimate and may vary depending on breed size, genetics, nutrition, and overall health.
Puppy Age FAQ
Is one dog year always equal to seven human years?
Not exactly. Puppies grow much faster during their first year, so the simple seven-year rule is only a rough estimate.
Do small and large dogs age differently?
Yes. Larger breeds often mature and age differently from smaller breeds, so this calculator should be used as a general guide.
