Quick check: is your pet underweight, ideal, or overweight?

How We Estimate BMI
This tool approximates the veterinary Body Condition Score (1-9 scale). We compare your pet's weight against breed-size reference ranges. A score of 4-5 is ideal — ribs easily felt but not visible, with a clear waist from above.
Estimate only. A veterinarian's hands-on assessment is the gold standard.
