Dog Body Condition Score

The 1–9 body condition score is how vets judge whether a dog is too thin, just right or carrying extra weight. Score your dog, then see their ideal weight.

Score your dog

6/9 · Slightly heavy

Ribs: Ribs felt with slight excess fat.

Waist: Waist visible from above but not prominent; slight tuck.

55lb estimated ideal weight

About 5.5 lb to lose. At a safe 1–2% a week, that takes roughly 6 weeks.

How to score in 60 seconds

  1. Feel the ribs. Flat hands on the chest. Knuckles of a fist = too thin; back of the hand = ideal; palm = overweight.
  2. Look from above. You should see an hourglass waist behind the ribs.
  3. Look from the side. The belly should tuck up from the chest toward the hind legs.
  4. Check the tail base and back for fat pads.

This is the 9-point system validated by Laflamme (1997) and used on the WSAVA body condition chart. Each point above 5 is about 10% extra body weight, which is how PawCalc estimates the ideal weight.

Long or thick coats hide a lot; always feel, don’t just look.

Step through the nine scores

Watch the waist and ribs change as body fat rises. Scores 4 and 5 are the healthy zone; by 7 the hourglass is gone.

Questions owners ask

What is a dog body condition score?
A 9-point scale vets use to judge body fat by look and feel: 1 is emaciated, 5 is ideal, 9 is severely obese. It comes from Laflamme’s 1997 validation study and is used in the WSAVA Global Nutrition Guidelines.
How do I score my dog at home?
Feel the ribs with flat hands (they should feel like the back of your hand), look down from above for a waist behind the ribs, and look from the side for the belly to tuck up toward the back legs. Pick the description on this page that fits best.
Is there a BMI for dogs?
Not a standard one; dog breeds differ too much in shape. The body condition score plays that role. Each point above 5 means roughly 10% more body weight than ideal, which lets you estimate an ideal weight, as this calculator does.
How much should my dog weigh?
Breed ranges are a starting point, but individuals vary. Use your dog’s current weight and body condition score above to estimate the ideal weight for your dog, then confirm with your vet.
Does being lean really matter?
Yes. In a lifelong Purina study of Labrador retrievers (Kealy et al., JAVMA 2002), dogs kept lean lived a median of about 1.8 years longer and developed osteoarthritis later than their heavier littermates.
Does muscle count too?
Yes. Vets also assess a separate muscle condition score over the spine, shoulders and hips. Older and ill dogs can lose muscle while still carrying fat, so ask your vet to check both.
