How Puppy Weight Prediction Works
Current Weight Method:Uses your puppy's current weight and age with breed-specific growth curves. Most accurate for puppies 8-20 weeks old.
Parent Weight Method: Averages mother and father weights with adjustment for sex (males typically 10-15% heavier). Best for purebred puppies or when parent weights are known.
Growth Rates by Size:
- Toy breeds: Reach adult weight by 6-8 months
- Small breeds: Reach adult weight by 8-10 months
- Medium breeds: Reach adult weight by 12 months
- Large breeds: Reach adult weight by 15-18 months
- Giant breeds: Reach adult weight by 18-24 months
