Body Condition Score (BCS) Chart for Dogs and Cats
Body Condition Score (BCS) is the standardised way to communicate a patient's nutritional status. The 9-point scale runs from emaciated (1) to morbidly obese (9), with ideal in the middle (4–5). Use it at every wellness visit, then compare exam-to-exam.

How to perform a BCS exam
- Rib palpation: Run your fingertips over the rib cage. Ribs should be easily palpable with light pressure, with minimal fat covering.
- Visual waist: View the patient from above. There should be a visible "hourglass" indentation behind the ribs.
- Abdominal tuck: View from the side. The abdomen should tuck up behind the rib cage.
What to do with the result
BCS 4–5 is ideal. Each score above ideal represents roughly 10–15% over ideal body weight. So a BCS 7 patient is approximately 20–30% overweight. Use the calorie calculator (RER × 1.0 for ideal weight) to plan a weight loss program.
Tips for accuracy
- Always palpate, don't just look. Long coats hide a lot.
- Use the same scale (1–9) at every visit. Mixing 1–5 and 1–9 systems creates confusion.
- Photograph the patient from above and the side at each visit - it helps owners see changes.
Frequently asked questions
What is an ideal BCS for a dog or cat?
On the WSAVA 9-point scale, an ideal score is 4-5/9 - ribs palpable with a thin fat covering, visible waist from above, abdominal tuck from the side. Score 6-7/9 is overweight; 8-9/9 is obese. Score 1-3/9 indicates underweight.
How is BCS assessed?
Three checks: (1) palpate ribs - you should feel them easily with light pressure, like running fingers over the back of a hand. (2) Look from above - there should be a visible waist behind the ribs. (3) Look from the side - the abdomen should tuck up from chest to groin. Loss of any of these = overweight.
Is the 9-point or 5-point scale better?
The 9-point WSAVA scale is the clinical standard - more granular, so you can detect small changes between exams. The 5-point scale is sometimes used in pet stores; each point on a 5-point scale roughly equals 1.5-2 points on the 9-point.
