Pet BMI Calculator
Check if your dog or cat is at a healthy weight. Calculate pet body condition score and get ideal weight range by breed and size.
About Pet Body Condition
Traditional BMI does not work well for pets due to the huge variation in body types across breeds. Veterinarians use the Body Condition Score (BCS) system, a 1-9 scale where 4-5 is ideal. This tool provides an estimate based on weight and breed size category. For the most accurate assessment, have your veterinarian evaluate your pet in person. Maintaining a healthy weight can add 2+ years to your pet's lifespan and reduce risk of diabetes, joint problems, and heart disease.
