  • 6 to 7 is overweight; 8 to 9 is obese.
  • Feel as well as look, especially in long-coated dogs.
  • Owners often underestimate their dog's score.

A body condition score (BCS) is a hands-on way to tell whether your dog is underweight, ideal or overweight. Vets look at your dog's shape and feel for fat over the ribs, spine and hips, then give a score.1,2 Most vets use a 9-point scale, recommended by the World Small Animal Veterinary Association (WSAVA) and the American Animal Hospital Association (AAHA). On that scale, 1 is emaciated, 9 is severely obese and 4 to 5 is ideal.2,3,4 Some use a 5-point scale, where 3 is ideal.5 At an ideal score, you can feel the ribs easily under a thin layer of fat, see a waist from above and see the belly tuck up from the side.2,6 Scores of 6 to 7 out of 9 mean overweight, and 8 to 9 mean obese.7,8 Each point above 5 is about 10% extra body weight.8,9 Body condition scores track body fat measured by scans closely, so they're more useful than a breed weight chart.10,6

See your vet if your dog:

  • Scores 3 or below, with ribs, spine or hip bones easy to see11,2
  • Is losing muscle along the spine, hips or head, even if it isn't thin12,4
  • Scores 8 or 9, or has gained weight quickly13,14

What the Research and Guidelines Say

  • Scores match body fat scans. In a study of 23 dogs, the 9-point score agreed closely with body fat measured by DEXA scanning (r² = 0.92).10
  • Owners underestimate. In a 2023 French study, 27% of dog owners underestimated their dog's body condition, and being overweight was the strongest predictor.15
  • Even professionals disagree. In a 2024 study of 43 working dogs, handlers scored their dogs significantly leaner than vets did.16
  • "Normal" may not be. In the 2022 APOP survey, 36% of owners called their dog normal weight when the vet scored it 6 or higher.7

Dog Body Condition Score Chart (9-Point Scale)

ScoreWhat you see and feel
1 to 3: Too thinRibs, spine and hip bones easy to see. At 3, ribs are easy to feel and may be visible, with an obvious waist and tuck. At 1, there is no body fat and obvious muscle loss.2
4: Ideal (lean)"Ribs easily palpable, with minimal fat covering." Waist easy to see from above.2
5: IdealRibs can be felt without extra fat. Waist visible behind the ribs from above, belly tucked up from the side.2
6: OverweightRibs can be felt with slight extra fat. Waist visible but not prominent.2
7: Overweight"Ribs palpable with difficulty; heavy fat cover." Fat over the lower back and tail base. Waist absent or barely visible.2
8: ObeseRibs can't be felt under very heavy fat, or only with firm pressure. No waist.2
9: Severely obeseMassive fat over the chest, spine and tail base, fat on the neck and legs, and an obviously swollen belly.2

The Association for Pet Obesity Prevention estimates body fat at about 20% to 24% for a score of 5 and 40% or more for a score of 9.6

How to Score Your Dog at Home

  1. Feel the ribs. Run your hands along both sides of the chest with light pressure. At an ideal weight, the ribs are easy to feel under a thin, even layer of fat but don't feel sharp.6
  2. Look from above. You should see a waist behind the ribs, like an hourglass.17,2
  3. Look from the side. The belly should tuck up behind the ribs.17,2
  4. Check the base of the tail. Fat pads there are a sign of being overweight.2

A long or thick coat can hide a dog's shape, so feel as well as look.17,6 Checking once a month is practical for many healthy adult dogs.6

9-Point vs 5-Point Scales

AAHA suggests "universal use of the 9-point (1–9) BCS scale with whole integers."4 On the 5-point scale, 1 is very thin, 3 is ideal and 5 is obese. A 3 out of 5 equals 4 to 5 out of 9.5,18 Ask your vet which scale they use, since a "4" means ideal on one scale and overweight on the other.5

Muscle Condition Score

Body condition measures fat. Muscle condition is scored separately, by feeling the muscle over the spine, shoulder blades, skull and hips. It's graded as normal or mild, moderate or severe muscle loss.12,4 An overweight dog can still be losing muscle, especially as it ages or if it's ill.12,17

Limits of Body Condition Scoring

  • Breed shapes differ. A Greyhound at a score of 5 has much less body fat than a Husky or Rottweiler at 5.17
  • Puppies and seniors are harder to score. Puppies have less waist and tuck, and older dogs tend to gain fat and lose muscle.17
  • It's subjective. Scores vary between people, so ask your vet to score your dog at each visit.16,4
