1. What is a Puppy Size Calculator?

Definition: This calculator estimates how big a puppy will get as an adult based on its current weight and age.

Purpose: It helps pet owners and breeders predict the adult size of a puppy for proper care planning.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Adult Size — Estimated weight when fully grown (kg)
• Puppy Weight — Current weight of the puppy (kg)
• Age in Weeks — Current age of the puppy (weeks)

Explanation: The formula assumes linear growth rate and projects the puppy's weight at 52 weeks (1 year).

3. Importance of Puppy Size Estimation

Details: Knowing the expected adult size helps with nutrition planning, crate sizing, exercise needs, and overall care requirements.

4. Using the Calculator

Tips: Enter the puppy's current weight in kg and age in weeks (between 1 and 52). All values must be > 0.
