1. What is the Puppy Growth Calculator?

The Puppy Growth Calculator estimates your puppy's adult size based on their current weight, age, and breed size factor. This helps predict how big your puppy will get when fully grown.

2. How Does the Calculator Work?

The calculator uses the puppy growth formula:

Where:

• Puppy Weight — Current weight in pounds
• Puppy Age — Current age in weeks (1-52)
• 52 — Number of weeks in a year
• Breed Factor — Multiplier based on breed size

Explanation: The formula projects current growth rate to one year, adjusted by breed-specific factors.

3. Importance of Breed Size Factors

Details: Different dog breeds grow at different rates. Small breeds mature faster while giant breeds continue growing longer.

4. Using the Calculator

Tips: For most accurate results, weigh your puppy at 14-16 weeks. Use breed-specific factors when available.

Q5: Should I be concerned if my puppy is under/over the estimate?
A: Consult your vet if significantly different, as nutrition or health issues may affect growth.
