How big will your "little" buddy actually get? Our predictor uses growth curves tailored to different breed sizes for maximum accuracy.

Puppies grow fastest between 3-6 months. Large breeds grow for up to 2 years!

The Science of Puppy Growth

I genuinely hate generic "multiply by 2" formulas. Growth isn't linear. A Great Dane щенку (puppy) grows at a completely different rate than a Frenchie. While most small dogs are close to their full size by 9 months, giant breeds keep filling out until they are two years old.

When to use this? This calculator is most accurate between 12 and 24 weeks of age. If your puppy is only 4 weeks old, it's too early to tell—the genetics are still warming up! If they are over 10 months, they are likely already at 90% of their final weight.

Growth Milestones:

  • Small Breeds: Often hit 50% of adult weight by 3 months.
  • Medium Breeds: Hit 50% by 4 months.
  • Large/Giant Breeds: Might only be 50% at 5-6 months.
