Body Condition Score (BCS) Guide
The BCS is a 9-point scale used by veterinarians worldwide to assess pet body condition. It's more reliable than weight alone because it accounts for breed and frame size differences.
| Score | Classification | What You See/Feel | % Over/Under Ideal |
|---|---|---|---|
| 1-2 | Underweight | Ribs, spine visible; no body fat | 20%+ under |
| 3 | Thin | Ribs easily felt; waist obvious | 10-15% under |
| 4-5 | Ideal | Ribs felt with light pressure; visible waist | 0% |
| 6-7 | Overweight | Ribs hard to feel; no visible waist | 10-20% over |
| 8-9 | Obese | Ribs not palpable; heavy fat deposits | 30%+ over |
