Dog Body Condition Score Calculator - Visual 9-Point Scale
Assess your dog's body condition at home using the same 9-point BCS scale veterinary clinics use worldwide - ribs, waist and abdominal tuck.
Body Condition Score (1-9)
1 = ribs prominent | 3 = easy to feel | 5 = hidden under fat
1 = severe tuck | 3 = clear waist | 5 = no waist
1 = exaggerated | 3 = slight tuck | 5 = no tuck or sagging

Body Condition Score (BCS) is the standardised way veterinarians describe whether a dog is underweight, ideal or overweight. The 9-point scale is more precise than the simpler 5-point version and is used in clinics worldwide.
Use the three sliders below to score your dog at home in under a minute.
What the scores mean
A BCS of 4 or 5 out of 9 is ideal. 1 to 3 indicates underweight, with 1 being severely emaciated. 6 to 7 indicates overweight. 8 and 9 indicate obesity, which carries the same health risks for dogs as it does for humans.
Every increase of one point on the 9-point scale corresponds to roughly 10 to 15 percent above ideal body weight.
How to assess at home
Stand your dog on a flat surface. Run flat hands gently along the ribcage - you should feel ribs easily, like the back of your own hand. Look down from above: there should be a clear narrowing behind the ribs. From the side, the belly should tuck upward toward the back legs.
- Ribs: easy to feel under a thin fat layer.
- Waist: clearly visible from above.
- Belly: tucks up from chest to back legs.
What to do at each score
Score 1-3: increase calories by 10-20%, rule out parasites and dental issues. Score 4-5: maintain. Score 6-7: reduce calories by 10-15% and add a daily 10-minute walk. Score 8-9: speak to your vet about a structured weight-loss plan.
Frequently asked questions
How often should I check BCS?
Monthly is ideal - it catches drift before it becomes a problem.
Is a 9-point or 5-point scale better?
The 9-point scale is more sensitive and is the modern veterinary standard.
Can my dog be fluffy and still healthy weight?
Yes - coat can hide shape. Always combine a visual check with hands-on rib palpation.
