Body Condition Score Guide
Check your dog's or cat's body condition on the 9-point scale vets use: answer three questions about ribs, waist and belly, then compare with each score's description.
With the dog standing and relaxed, answer each question with the closest description. A long coat hides shape, so trust your hands more than your eyes.
Answer the three questions to see the nearest score for your dog.
The 9-point scale for dogs
Read the description for your result and the ones either side of it, and pick the one that fits best. The outlines show the waist seen from above.
1: Below ideal
Ribs, spine and hip bones visible from a distance. No body fat, and obvious loss of muscle.
2: Below ideal
Ribs, spine and hip bones easily visible. No fat can be felt, with some loss of muscle.
3: Below ideal
Ribs easily felt and may be visible, with no fat over them. Tops of the spine visible, hip bones becoming prominent. Obvious waist and tuck.
4: Ideal
Ribs easily felt with a minimal covering of fat. Waist easily seen from above; belly clearly tucked.
5: Ideal
Ribs felt without excess fat covering. Waist seen behind the ribs from above; belly tucked up when seen from the side.
6: Above ideal
Ribs felt with a slight excess of fat. Waist visible from above but not prominent; belly tuck still there.
7: Above ideal
Ribs felt only with difficulty under heavy fat. Fat noticeable over the lower back and base of the tail. Waist absent or barely visible; there may still be a tuck.
8: Well above ideal
Ribs cannot be felt under very heavy fat, or only with firm pressure. Heavy fat over the lower back and tail base. No waist and no tuck; the belly may be visibly swollen.
9: Well above ideal
Large fat deposits over the chest, spine and tail base, and on the neck and legs. No waist or tuck; the belly is obviously swollen.
A guide for healthy animals, not a diagnosis. The score measures fat, not muscle: older or ill animals can lose muscle while keeping fat, which a vet checks separately. Ask your vet to confirm the score, and before starting any weight change.
What body condition scoring is
Weight on its own does not tell you whether an animal is too fat or too thin. A 30 kg dog can be lean or heavy depending on its frame, and a 5 kg cat can be ideal or overweight. Body condition scoring answers that question by looking at and feeling the fat over the body.
Many vets use a 9-point scale for dogs and cats, where 1 is emaciated, 5 is ideal and 9 is severely obese. Scores of 4 and 5 are usually counted as the ideal range. Each point is described by what you can feel over the ribs, the waist you can see from above and the line of the belly from the side. This guide uses the same three checks.
How the guide works
- Choose dog or cat. The ribs and waist checks are the same; the belly check differs, because many cats have a loose flap of skin on the lower belly (the primordial pouch) that is normal and is not fat.
- Answer three questions with the description closest to what you feel and see.
- Read the result. Each answer points to a score; the ribs count twice, because feeling the ribs is the most reliable of the three checks, especially under a thick coat. The average is rounded to the nearest whole score.
- Compare with the chart. The guide shows the description for your result and the full scale. Read the scores either side too, and pick the one that fits best. If your three answers point to very different scores, the guide says so.
The outlines next to each score show the waist seen from above, from an hourglass at the thin end to sides that bulge outwards at the heavy end. They are simple shapes to help you picture the description, not drawings of a real animal.
How to check, step by step
- Ribs. With the animal standing, run your flat hands along its chest with light pressure, as if stroking it. At an ideal condition you feel each rib easily under a thin layer of fat. If you have to press to find them, there is too much fat; if you can see them clearly, there is too little.
- Waist. Stand over the animal and look down. Behind the ribs, there should be a visible waist before the hips.
- Belly. Look from the side. In a dog, the belly line should rise from the chest towards the back legs. In a cat, look and gently feel for a fat pad on the lower belly.
A long or thick coat can hide all of this, so trust your hands more than your eyes.
A worked example
An owner checks her neutered adult dog. She can feel the ribs, but only through a noticeably thicker layer of fat than she expected. From above, there is a waist, though not a prominent one. From the side, the belly has only a slight tuck. The guide gives a score of about 6 out of 9: above ideal. She reads the descriptions for 5, 6 and 7, agrees that 6 fits, and books a check with her vet before changing the dog's food.
Limits of the guide
- It is a guide, not a diagnosis. The three questions point to the nearest description; the hands-on score from a vet is the reference.
- It measures fat, not muscle. Older or ill animals can lose muscle while keeping fat, so a dog can have a normal score and still be unwell. Vets assess muscle separately.
- Shape can fool the eye. Breeds differ in build, and posture and coat change how an animal looks. When the checks disagree, rely on the ribs.
- It is for healthy adult animals. Puppies, kittens, pregnant animals and animals with swelling of the belly need a vet, because a round belly can be a medical problem rather than fat.
What to do with the result
Score the animal every few weeks, alongside a weigh-in on the same scales, and note both. A score within 4 to 5 that stays steady means the feeding is about right. A score above ideal is a reason to see the vet before changing the diet: they can rule out medical causes and agree a safe target. For cats, never cut food sharply or fast them, because rapid weight loss can cause fatty liver disease. A score below ideal, or any unexplained weight loss, also needs the vet.

Frequently asked questions
What is the ideal body condition score for a dog or cat?
On the 9-point scale, 4 to 5 is ideal, and many vets aim for 5: ribs easy to feel under a thin layer of fat, a visible waist from above and a tucked belly from the side.
Is body condition score better than weight?
They answer different questions. Weight tells you whether the animal is changing; body condition tells you whether that weight is right for its frame. Use both, on the same scales, every few weeks.
My pet scored above ideal. Should I cut its food?
Talk to your vet first. They can rule out medical causes and set a safe target and rate of loss. For cats this matters even more: cutting food sharply can cause fatty liver disease, so never fast a cat.
