Puppy Growth Curves
Puppies grow at different rates depending on their breed size. Toy breeds reach full size quickly (around 6-9 months), while Giant breeds (like Great Danes) continue growing for up to 18-24 months.
Estimation Method
- Formula: (Current Weight / Age in Weeks) × 52.
- This gives a rough estimate for medium breeds.
- Our tool uses specific growth curves to adjust for Toy vs. Giant breeds for better accuracy.
