Frequently Asked Questions (FAQ)

1. What is a Dog BMI Calculator?

The Dog BMI Calculator measures your pet’s Body Mass Index to determine if they’re underweight, healthy, overweight, or obese. It uses weight, height, and breed size for accurate results.

2. How do I measure my dog’s height correctly?

Measure from the ground to the shoulder (withers) while your dog stands straight. Use a tape measure in centimeters for precision.

3. Why does breed size matter in BMI calculation?

Small breeds (e.g., Chihuahuas) and giant breeds (e.g., Great Danes) have different healthy weight ranges. Our calculator adjusts thresholds for accurate, breed-specific results.

Yes! It’s optimized for all sizes (small, medium, large, giant). For mixed breeds, choose the closest weight category.
