Look at the waist from above and abdominal tuck from the side, then gently feel the ribs. Choose the closest score.
π BCS Self-check Report
Pet: πΆ Dog, current weight: Not entered, selected BCS: β/9
BCS group: [Not selected]. This group comes only from the BCS you selectedβnot from current weight or a breed average.
No breed range is selected. Breed information does not change the BCS result.
This educational result groups the score you selected; it is not an automated diagnosis. Coat, posture, frame, age, and muscle mass can affect a home estimate, and BCS does not replace a muscle condition score (MCS). Ask a veterinarian for a hands-on assessment after an unexplained weight change or when the score appears to be 1β3 or 6β9.
π‘ Understanding the 9-point BCS Scale
1. How do I choose a BCS?
View your pet from above and from the side, then use both hands to feel the ribs. A visual check alone can be misleading under a long or dense coat.
- 1β3, under ideal: ribs and bony points are easy to see or feel; the waist and abdominal tuck are pronounced.
- 4β5, ideal: ribs are easy to feel without excess fat; a waist and abdominal tuck are visible.
- 6β7, over ideal: added fat makes the ribs harder to feel and the waist less distinct.
- 8β9, obese: ribs are difficult to feel under a heavy fat layer, with little or no waist.
Reference: AAHA 9-point BCS guidance, the WSAVA dog BCS chart, and the WSAVA cat BCS chart.
2. Does a breed weight range determine the result?
No. Healthy weight varies with sex, frame, age, and muscle mass even within one breed. The breed table is optional context for recording weight; it never changes the BCS group shown above.
3. Is BCS the same as human BMI?
No. Dogs and cats vary greatly in frame and body shape, so a single human-style weight-and-height formula is not appropriate. Veterinary teams use visual and hands-on BCS assessment for body fat and assess muscle separately with MCS.
