1. What is the Puppy Adult Weight Calculator?

This calculator estimates a puppy's adult weight based on its current weight and age. The formula works best for puppies between 8-16 weeks old and provides a rough estimate of their full-grown size.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• Puppy Weight — Current weight in pounds (lbs) or kilograms (kg)
• Puppy Age — Current age in weeks (1-52)
• 52 — Number of weeks in a year

Explanation: This calculation assumes linear growth rate during puppyhood. The formula projects the current growth rate to one year (52 weeks).

3. Accuracy of the Prediction

Details: This method provides a rough estimate. Accuracy depends on breed, nutrition, and individual growth patterns. Large breeds may continue growing beyond 1 year.

4. Using the Calculator

Tips: For best results, weigh your puppy at 14-16 weeks. The calculation works best for medium-sized breeds. Very small or giant breeds may have less accurate predictions.

5. Frequently Asked Questions (FAQ)
