What is a Body Condition Score?

BCS is a visual and tactile evaluation of a dog's fat coverage on a 1–9 scale. Score 1 means severely underweight; 9 means morbidly obese. Ideal dogs score 4 or 5.

How do I check my dog's body condition?

Run your hands along your dog's ribs — you should feel them easily without pressing. Look down from above: there should be a visible waist behind the ribs. Look from the side: the belly should tuck up toward the rear legs.

My dog is BCS 7 — is that dangerous?

Yes, BCS 7 means roughly 20% over ideal weight. This significantly increases risk of arthritis, diabetes, and shortened lifespan. Reduce calories by 15–20% and increase activity gradually.

How fast can a dog safely lose weight?

1–2% of body weight per week is the safe target. For a 20 kg dog, that is 200–400 g weekly. Faster weight loss risks muscle loss and metabolic issues.

Reading The 9-Point Scale

Each tier has clear visual and tactile markers.

1️⃣

BCS 1–3 — Underweight

Ribs, spine, and pelvic bones visible from a distance. No fat coverage. Severe muscle loss in scores 1–2. Requires veterinary attention to identify the cause.

4️⃣

BCS 4–5 — Ideal

Ribs felt easily without pressure but not seen. Clear waist behind the ribs from above; visible abdominal tuck from the side. This is the target.

9️⃣

BCS 6–9 — Overweight

Score 6 is mild excess fat. Score 7 is clinically overweight. Scores 8–9 are obesity, with major fat pads, no waist, and abdominal sag. Calorie restriction needed.

How We Combine Your Answers

Final BCS = round((Rib + Waist + Belly) / 3) on 1–9 scale

Rib palpation carries the most diagnostic weight in veterinary practice

The 9-point scale was developed by Purina and adopted by WSAVA as the global standard. Each two-point shift represents roughly 10% of body weight away from ideal.
