1. What is a Dog Size Calculator?

Definition: This calculator estimates a puppy's adult weight based on its current weight and age in weeks.

Purpose: It helps dog owners predict their puppy's adult size for proper care, nutrition planning, and preparation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Adult Weight — Estimated full-grown weight (pounds)
• Puppy Weight — Current weight of the puppy (pounds)
• 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 Size Estimation

Details: Knowing your dog's potential adult size helps with proper nutrition planning, crate sizing, exercise needs, and health monitoring.
