1. What is the Puppy Growth Calculator?

The Puppy Growth Calculator estimates how big your puppy will get when fully grown based on their current weight and age. This simple formula works best for medium-sized breeds.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

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

Explanation: The calculation assumes your puppy will grow at a consistent rate until reaching adult size at about 1 year (52 weeks).

3. Accuracy of the Calculation

Details: This method provides a rough estimate. Accuracy varies by breed - it works best for medium-sized breeds and is less accurate for very large or small breeds.

4. Using the Calculator

Tips: For best results, weigh your puppy at 14-16 weeks old. Make sure to use exact weight in kilograms and precise age in weeks.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It's about 75% accurate for medium breeds. Giant breeds may continue growing beyond 1 year, while small breeds may reach full size earlier.

Q2: When is the best time to calculate adult weight?
A: Between 14-16 weeks gives the most reliable estimate. Earlier calculations may overestimate, while later ones may underestimate.

Q3: Does this work for all dog breeds?
A: It works best for medium-sized breeds (20-50 kg adult weight). For giant breeds, multiply the result by 1.1-1.2; for small breeds multiply by 0.8-0.9.

Q4: What if my puppy is under or overweight?
A: The calculation assumes normal weight. Overweight puppies will produce overestimates, underweight puppies will produce underestimates.

Q5: Are there other methods to predict adult size?
A: Yes, you can also look at paw size, consult growth charts specific to your breed, or ask your veterinarian for a more accurate assessment.
