What is a body condition score?

BCS is a 1–9 visual/physical scale used by vets to assess whether a dog or cat is at a healthy weight. 4–5 is ideal, 6–7 is overweight, 8–9 is obese, 1–3 is underweight. It's more reliable than the scales alone because it accounts for frame size and muscle.

Is my dog overweight?

Three quick checks: (1) can you feel ribs easily without pressing? (2) is there a visible waist when viewed from above? (3) does the belly tuck up from ribcage to hips when viewed from the side? Answer "no" to any of those and your dog is likely overweight — our BCS tool scores this in 30 seconds.

Cats are especially prone to creeping weight gain. Key signs: ribs that can't be felt, no visible waist, a saggy belly pouch (distinct from the normal "primordial pouch" which is loose skin even in lean cats). Over 60% of U.S. cats are now overweight — a quick BCS check catches it early.

What should I do if my pet is overweight?

Start with a vet weigh-in to rule out medical causes (thyroid in dogs, diabetes in cats), then calculate daily calorie needs (our feeding calculator helps), reduce treats to under 10% of calories, and add short daily activity. Aim for 1–2% bodyweight loss per week — faster can be unsafe.

How accurate is a home BCS check?

A careful home check correlates well with vet-performed BCS and is far better than scale weight alone. But if your pet is very fluffy, very muscular (some breeds), or you're unsure, ask your vet to hand-score on the next visit — takes 30 seconds.

Is your pet the
right weight?

The Body Condition Score (BCS) is how vets assess pet weight — it's more reliable than scales alone. Three simple hands-on checks and you'll know where your pet sits on the 1–9 scale.

1. Feel the ribs (along the side of the chest)

2. Look from above — is there a waist?

3. Look from the side — does the belly tuck up?

The 1–9 scale.

This is the standard scale used by US vets (WSAVA).

1–3: Underweight → ribs visible, no fat cover, prominent waist. Vet visit.
4–5: Ideal → ribs felt easily, visible waist, belly tucks up. Keep it up.
6–7: Overweight → ribs harder to feel, waist disappearing, slight belly sag. Adjust portions.
8–9: Obese → ribs not felt under fat, no waist, rounded belly. Vet-guided plan.

Weight changes matter more than absolute score. A BCS 7 cat that's been that way for years is less urgent than a BCS 5 cat that jumped to 7 in three months — that shift needs a vet check.

Long-haired pets can look heavier than they are — always use touch, not just sight.
