What is a Puppy Growth Calculator?

A Puppy Growth Calculator is a tool that helps estimate the final adult weight of your puppy based on their current weight, age, and breed size. This is especially designed for new pet owners who want to know how big their puppy will become.

How the Puppy Growth Calculator Works

The calculator uses the puppy's current weight and age to predict their future size by factoring in the typical growth rate of their breed size. Small breeds tend to mature faster, while large and giant breeds continue growing for a longer period.

Puppy Growth Calculator Formula

The formula is based on the general growth rate of the breed size. For example, small breeds often reach their adult weight by 12 months, while giant breeds can continue growing for up to 24 months. The calculation uses the puppy's age in weeks and current weight to estimate the final weight.
