Many pets are too fat. This gives the same health risks as for humans. Although not generallly accepted yet in the medical vetenerian world, recently several scientific researches have proved that cats, small and medium size dogs should not have a BMI larger than 15. About the minimum BMI for pets is not much known yet. After having done some empirical research myself, I came to the conclusion that for certain pets, dependent on their structure and breed, a BMI of 10 is already fine! As there hasn't done any decent research yet about the optimal BMI for pets, I started a research myself, by this website. The goal is to collect bmi data of many pets of many breeds living around the world. Would you like to help me with my research? Then click here to fill in the survey about your pet. It is anonymous.

How do you measure the BMI in your cat or dog? Easiest way is that one person holds the pet in the way as shown on the picture, while another person measures the height of the pet. Then you weight yourself and write down your weight. Take your pet in your arms and weight yourself again. The difference is the weight of your pet. Now you can enter the height and weight of your pet into our BMI Calculator and the calculator will do the rest for you.
