How Does the Puppy Weight Calculator Work?

Puppies grow at different rates depending on their breed and expected adult size. This calculator uses your puppy’s current age and weight to provide an approximate adult weight estimate.

The result is only an estimate. Genetics, nutrition, health, breed, and individual growth patterns can all affect your puppy’s final size.

Puppy Growth Guide

Small breeds often reach their adult size earlier than large and giant breeds. Large puppies may continue growing for 18 months or longer.
