Dog body condition score checker

Answer four quick hands-on checks: ribs, waist, belly and the base of the tail. You get your dog's score on the 9-point scale vets use, its likely body fat, and an ideal weight if you add the current weight.

Check your dog

1. Ribs

Run your flat hands along your dog's sides with light pressure.

2. Waist, seen from above

Stand over your dog and look down at the part behind the ribs.

3. Belly, seen from the side

Look at the line from the end of the chest to the back legs.

4. Lower back and base of the tail

Look at and feel the area just in front of the tail.

5. Muscle

Feel over the spine, shoulder blades, skull and hips. Muscle is scored separately from fat.

Weight (optional)

For an ideal weight estimate

Body condition score

–out of 9

Answer the four checks on the left (0 of 4 done). Ideal is 4 or 5 out of 9.

1: Ribs, spine and hip bones visible from a distance. No body fat; obvious muscle loss.
3: Ribs easy to feel and may be visible, with no fat on them. Tops of the spine visible, hip bones showing. Obvious waist and tuck.
4: Ribs easy to feel under a thin layer of fat. Waist easy to see from above; belly clearly tucked.
5: Ribs can be felt without extra fat over them. Waist visible behind the ribs from above; belly tucked up from the side.
7: Ribs hard to feel under heavy fat. Fat pads over the lower back and base of the tail. Waist barely visible or gone.
9: Massive fat over the chest, spine and tail base, and on the neck and legs. No waist; belly clearly bulges.

A home estimate based on the WSAVA body condition chart, not a diagnosis. Sudden weight loss or gain can be a sign of illness, so ask your vet to confirm the score.

The 9-point dog body condition score chart

Vets score body condition from 1 (emaciated) to 9 (severely obese). The scale was developed and checked against body-fat scans in the 1990s and is the one on the WSAVA body condition chart. 4 and 5 are ideal. The body-fat and overweight figures come from AAHA's 2021 nutrition and weight management guidelines.

Descriptions summarized from the WSAVA chart; body fat and % above ideal weight from AAHA 2021, Table 2.
Score	What you see and feel	Body fat	Above ideal
1 · Emaciated	Ribs, spine and hip bones visible from a distance. No body fat; obvious muscle loss.	–	underweight
2 · Very thin	Ribs, spine and hip bones easily visible. No fat you can feel; slight muscle loss.	–	underweight
3 · Thin	Ribs easy to feel and may be visible, with no fat on them. Tops of the spine visible, hip bones showing. Obvious waist and tuck.	–	underweight
4 · Ideal (lean)	Ribs easy to feel under a thin layer of fat. Waist easy to see from above; belly clearly tucked.	15–19%	ideal
5 · Ideal	Ribs can be felt without extra fat over them. Waist visible behind the ribs from above; belly tucked up from the side.	20–24%	ideal
6 · Overweight	Ribs can be felt under a little extra fat. Waist visible from above but not prominent; belly tuck still there.	25–29%	10%
7 · Heavy	Ribs hard to feel under heavy fat. Fat pads over the lower back and base of the tail. Waist barely visible or gone.	30–34%	20%
8 · Obese	Ribs can't be felt, or only with firm pressure. Heavy fat over the lower back and tail base. No waist, no tuck; belly may bulge.	35–39%	30%
9 · Severely obese	Massive fat over the chest, spine and tail base, and on the neck and legs. No waist; belly clearly bulges.	40–45+%	40%

Each step on the scale is about 5% more body fat, and each step above 5 is roughly 10% more weight than the dog should carry. So a 66 lb (30 kg) dog that scores 7 is about 20% heavy, and its ideal weight works out to about 55 lb (25 kg).

How to check your dog's body condition at home

Feel the ribs. Flat hands on both sides of the chest, light pressure, fingers moving over the ribs. At an ideal score they are easy to feel with only a thin covering. If you have to press to find them, your dog is carrying extra fat.
Look from above. With your dog standing, look down. There should be a visible waist behind the ribs, narrower than the chest and hips.
Look from the side. The belly line should rise from the end of the chest towards the back legs. A straight or sagging line means excess fat.
Check the base of the tail and lower back. Fat pads here show up from a score of 7. In thin dogs the tops of the spine and the hip bones become visible.

With fluffy or long coats, trust your hands over your eyes: a thick coat can hide both a waist and a bony back. Wet coats after a bath make the visual checks easier.

Why body condition matters more than the number on the scale

A scale tells you weight, not whether that weight is right for your dog. Breed standards are wide, mixed breeds have no standard at all, and muscle weighs in too. Body condition scoring works for any dog, which is why vets use it to set an ideal weight.

It also catches a problem owners tend to miss. AAHA notes that up to 59% of dogs and cats in the US are overweight, and that in one study 39% of owners whose dogs a vet called overweight thought their dog was at an acceptable weight. The stakes are real: in a study of 50,787 neutered pet dogs across 12 breeds, overweight dogs had shorter lives in every breed. The gap ranged from about 5 months in German Shepherds to about 2.5 years in Yorkshire Terriers.

Body condition vs muscle condition

Body condition measures fat. Muscle is scored separately, on a four-step scale from normal to severe muscle loss, by feeling over the spine, shoulder blades, skull and hips. The two do not always move together: WSAVA points out that an overweight dog can still have significant muscle loss, and a thin dog can have very little. Muscle loss can come with illness or with age, so if your dog feels bony over the spine or head while still carrying fat around the belly, mention it to your vet.

What to do with your dog's score

4 or 5: keep doing what you are doing, and recheck now and then. Treats should stay under 10% of daily calories.
6 or 7: a gradual weight-loss plan. The dog weight loss calculator gives a calorie target and a realistic timeline at a safe 1 to 2% of body weight a week.
8 or 9: book a vet visit first. Bigger calorie cuts call for a diet made for weight loss so your dog still gets all its nutrients, plus regular weigh-ins.
1 to 3: see your vet to find the cause before adding food. AAHA's guidelines treat any score below 4 or above 5 as a reason for a closer nutritional assessment. The weight gain calculator helps plan calories once illness is ruled out.

Frequently asked questions

What is a good body condition score for a dog?

A 4 or 5 on the 9-point scale. At those scores you can feel the ribs easily with only a thin layer of fat, see a waist behind the ribs from above, and see the belly tuck up from the side. VCA advises keeping growing large and giant breed puppies at 4.

Is a body condition score of 6 bad?

It is mildly overweight: AAHA's guidelines put a 6 at about 10% above ideal weight. It is not an emergency, but it is the easiest point to fix, usually by trimming portions and treats a little before the weight creeps up further.

How does the 9-point scale compare with a 5-point scale?

Each point on a 5-point scale equals two points on the 9-point scale. AAHA lines them up like this: 4 and 5 out of 9 are 2.5 and 3 out of 5, 6 is 3.5, 7 is 4, 8 is 4.5 and 9 is 5. AAHA recommends the 9-point scale with whole numbers.

Can my dog be a healthy weight on the scale but the wrong shape?

Yes. Two dogs of the same breed and weight can carry very different amounts of fat and muscle. That is why vets judge body condition by feel and shape, and score muscle separately: a dog can lose muscle while keeping, or even gaining, fat.

How often should I check my dog's body condition?

Make it a habit whenever you weigh your dog, and always after changing food or exercise. AAHA's guidelines ask vets to score body and muscle condition at every exam and to teach owners to do it at home, so ask your vet to check your scoring once.
