Body Condition Scoring
Learn how to evaluate your dog’s body condition using the Purina 9-Point Body Condition System and identify whether your dog is underweight, ideal, overweight, or obese.
How To Assess Your Dog
👋 Feel the Ribs
You should be able to feel your dog’s ribs easily with light pressure, but they should not be prominently visible.
🔍 Look for a Waist
Viewed from above, your dog should have a visible waist behind the rib cage.
📐 Check the Abdominal Tuck
Viewed from the side, the abdomen should rise upward behind the rib cage.
Ideal Body Condition (BCS 4–5)
✓ Ribs easily felt
✓ Visible waist from above
✓ Abdominal tuck from the side
✓ No excessive fat deposits
✓ Athletic appearance

BCS 9 – Severely Obese
Massive fat deposits. Significant health risk.
Working Dog Considerations
