Puppy growth tracking isn’t just curiosity — it’s a vital health indicator. Growth rate reveals if nutrition, exercise, and health care are appropriate.

- Too slow growth may indicate poor diet, worms, or underlying illness.

Dog Growth Stages Overview
| Stage | Age Range | Key Development Milestones |
|---|---|---|
| Neonatal | 0–2 weeks | Fully dependent on mother, minimal movement |
| Transitional | 2–4 weeks | Eyes open, first steps begin |
| Socialization | 3–12 weeks | Rapid growth, begins learning from environment |
| Juvenile | 3–6 months | Teeth development, fast muscle growth |
| Adolescence | 6–12 months | Growth rate slows, behavioral maturity begins |
| Adulthood | 12+ months (varies by breed) | Full size reached, weight stabilizes |
Small breeds often reach full size by 9–12 months, while large or giant breeds may continue growing until 18–24 months.
