1. What is the Puppy Weight Calculator?

The Puppy Weight Calculator estimates a dog's adult weight based on their current weight and age in weeks. This simple formula provides a rough prediction of how big your puppy will grow.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( AW \) — Predicted adult weight (kg)
• \( CW \) — Current weight (kg)
• \( CAW \) — Current age in weeks (1-52)

Explanation: The equation assumes linear growth rate during puppyhood and that most dogs reach adult size by 52 weeks (1 year).

3. Importance of Weight Prediction

Details: Knowing your puppy's potential adult size helps with planning living arrangements, food requirements, exercise needs, and anticipating any size-related health concerns.

4. Using the Calculator

Tips: For best results, weigh your puppy at the same time each day (preferably morning before feeding). The formula works best for puppies between 4-20 weeks old.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides a rough estimate. Accuracy varies by breed, with large breeds often continuing to grow beyond 52 weeks.

Q2: When does this formula work best?
A: It's most accurate between 12-20 weeks of age. Very young puppies (under 12 weeks) may show more variability.

Q3: Does breed affect the calculation?
A: Yes, giant breeds may continue growing up to 2 years, while small breeds may reach adult size earlier than 52 weeks.

Q4: Can I use pounds instead of kilograms?
A: The formula works with any unit as long as you're consistent (use pounds for both CW and AW).

Q5: What if my puppy is already over 52 weeks?
A: For dogs older than 1 year, they're likely at or near their adult weight already.
