Body weight alone does not tell you whether a pet is carrying too much fat, because two animals at the same 11 lb can have very different frames. This tool asks you about four things you can check at home: how the ribs feel under your palm, the waistline seen from above, the belly line seen from the side, and how the spine and hip bones feel.
Body condition score is standardly reported on a 9-point scale, and 4 to 5 points is treated as ideal. The 9-point scale is the one AAHA and WSAVA both use, while some material uses a 5-point scale, so always check which scale a record is on before comparing. This tool averages the four item estimates, rounds the average, and shows both the unrounded average and the formula it used. Guidance current as of October 2026.
A formal body condition score is assigned by a veterinarian with hands on the animal, so a score built from written descriptions can land one or two points away from a clinical score. This tool does not provide breed weight charts or an ideal-weight conversion. This tool is for reference only and does not replace veterinary care. Contact your veterinarian right away if you notice symptoms or suspect a problem.
Frequently Asked Questions
4 to 5 points is treated as ideal. 6 and above leans overweight, and 3 and below leans underweight.
Different scales give different numbers for the same body. This tool uses only the 9-point scale, so do not compare it directly with a 5-point record.
Safe weight-loss speed and a target weight depend on age and any underlying disease. Set the plan with your veterinarian.
