Calculatrice d'Âge de Chiot

The puppy age calculator helps you understand where your puppy is in their development journey by converting puppy months to equivalent human years.

Puppies develop at an astonishing rate. By 8 weeks old, a puppy is roughly equivalent to a 1-year-old human infant in development. By 1 year old, most breeds are roughly the equivalent of a 15-year-old teenager.

Understanding puppy development stages helps you set appropriate training expectations, recognize normal behaviors, and provide the right nutrition and socialization for each phase.

Puppy Development Stages

Neonatal (0–2 weeks): Eyes and ears closed. Completely dependent on mother. Equivalent to a newborn human.

Socialization (3–12 weeks): Critical learning period. Eyes open at 2 weeks, hearing at 3–4 weeks. Fear imprinting period begins at 8 weeks — this is the ideal adoption age.

Juvenile (3–6 months): Rapid growth. Puppy teeth falling out. Beginning to test boundaries. Equivalent to a 5–8 year old child.

Adolescence (6–18 months): Sexual maturity. Often pushes limits. Equivalent to a teenager (13–17 human years). Most challenging training period.

When Do Puppies Become Adult Dogs?

Small breeds (under 20 lbs): Reach adult size by 9–12 months. Considered adult at 1 year.

Medium breeds (20–50 lbs): Adult size by 12–15 months. Large breeds (50–90 lbs): Adult size by 18 months. Giant breeds (90+ lbs): May not reach full size until 18–24 months.

A 6-month-old puppy is roughly equivalent to a 10–12 year old human child. They're entering the juvenile phase, losing puppy teeth, and often becoming bolder.
