Calculadora de IMC do Cão

The Dog BMI Calculator is a tool that estimates your dog's body mass index, adapting the human concept for dogs. Unlike human BMI, which uses height, here we use body length, measured from the tip of the nose to the base of the tail, in meters. The calculation is simple: weight in kilograms divided by length squared. The result is a number indicating whether the dog is underweight, ideal weight, overweight, or obese, based on veterinary references.

How to use: measure your dog's length with a flexible tape measure while it is standing. Note the weight on a reliable scale. Enter the values into the calculator. The result is displayed with a classification: underweight, ideal weight, overweight, or obese. Remember: this is an indicative reference. The most accurate assessment is made by the veterinarian using the body condition score (BCS), which ranges from 1 to 9, with 5 being ideal.

Use this calculator to monitor your dog's weight between vet visits, especially if it tends to gain or lose weight. It is useful for medium to large breeds; very small dogs or those with atypical conformations (like bassets or bulldogs) may not fit well. The calculator does not replace a professional evaluation, but it helps identify changes that deserve attention.

Cautions: length measurement can vary depending on the dog's posture. Always measure in the same position. Canine BMI does not consider muscle mass, so very muscular dogs (like pit bulls) may show false overweight. Use BCS to confirm. Do not use for growing puppies or pregnant females. Consult a veterinarian to interpret results and plan diet or exercise.
