How the Dog BMI Calculator Works
This dog BMI calculator takes in to account the breed, height, weight and sex of your dog and then displays a BMI value. By itself this BMI value would be useless. It is not comparable to the human BMI range. Because we’ve taken individual breed specifications into account, we can give you a fairly accurate guide to whether your pet is underweight, overweight or at an ideal weight.
Each pedigree breed has specifications e.g. those published by the Fédération Cynologique Internationale. This specifications allow us to create a minimum and maximum BMI value for each breed. To some extent, there are now even specifications for mixed breeds.
The results page will show you the minimum and maximum BMI values for your dog’s breed.
This dog BMI calculator has been tested in a number of real-life scenarios. Various breeds and weights were used and in each scenario the height, weight, sex and breed were obtained. This was put in to the calculator and the results given. The weight status (i.e. underweight, overweight or ideal weight) determined by body condition scoring, matched the results from the BMI calculator, great news!
