What is a body condition score and how do I check it?
Last updated 23 September 2026 · How we write and check this
Short answer
Body condition score is a simple hands on scale, commonly out of 9, used to judge whether a dog is underweight, healthy, or overweight based on how easily you can feel the ribs, whether a waist is visible, and how much fat covers the belly and hips. A healthy adult dog typically scores 4 or 5 out of 9, with the ribs easily felt and a clear waist visible from above.
How the scale works
At the low end, around 1 to 3, ribs, spine, and hip bones are all clearly visible with little to no fat covering, indicating an underweight dog. At the healthy middle, around 4 to 5, ribs are easily felt under a thin layer of fat, with a visible waist and belly tuck.
At the high end, around 6 to 9, ribs become progressively harder to feel under fat, the waist disappears, and at the most extreme scores there may be visible fat deposits over the back and base of the tail.
Doing the check yourself
Feel along the ribs with flat hands and light pressure, look at the waist from directly above, and check the belly tuck from the side, comparing what you see and feel against the general 1 to 9 descriptions.
This takes only a minute or two once you know what to check, and is worth doing every couple of weeks rather than relying on the bathroom scale number alone, since weight alone does not show where that weight sits.
Using the score over time
Ask your vet to show you your specific dog's current score at a routine visit, since learning by feel with guidance is much easier than working from a written description alone.
Track the score alongside actual weight over months, since a rising number even with a stable weight can indicate muscle loss being replaced by fat, which is worth mentioning to your vet.
Key takeaways
- Body condition score is a hands on scale, commonly out of 9, judging fat covering rather than weight alone.
- A healthy adult dog typically scores 4 or 5, with easily felt ribs and a visible waist.
- Check the ribs, waist from above, and belly tuck from the side to estimate the score yourself.
- Ask your vet to demonstrate your dog's specific score at a routine visit to learn the technique accurately.
