How It Works
The growth chart uses breed-size maturity curves to calculate expected weight at each milestone. The predicted adult weight is derived from the current weight-to-age ratio. Each milestone is then calculated as the proportional share of adult weight at that checkpoint age. The current week row is highlighted so you can instantly see where your puppy sits today.
Checkpoints are set at the clinically useful ages when vets typically weigh puppies — aligning the chart with real vaccination and health check visits for easy comparison.
Veterinary Research
Every formula is derived from peer-reviewed veterinary studies and clinical guidelines, not guesswork or generic rules.
