Roughly half of pet dogs in the UK and US are estimated to be overweight or obese, and it's often hard for owners to notice gradual weight gain in their own pet. Vets use a hands-on 9-point Body Condition Score (BCS) — feeling for ribs, looking for a waist from above and a belly tuck from the side — rather than weight alone, since ideal weight varies hugely by breed and frame size. This model reshapes a stylised 3D dog to show what each BCS zone actually looks and feels like.
Even a modest amount of excess weight meaningfully shortens a dog's life — a landmark Labrador Retriever lifetime study found dogs kept at an ideal body condition lived, on average, about 1.8 years longer than their overweight littermates.
An interactive 3D dog body-condition model that reshapes its ribcage, waist and belly as you move a weight slider, while a vet-style 1–9 Body Condition Score gauge and a floor ring compare current weight against the breed's ideal.
Weight is only meaningful relative to a dog's frame size — the same kilogram figure can be lean on a large breed and dangerously obese on a small one. The rib-check overlay and BCS gauge show how vets actually assess body condition by feel and sight, not the scale alone.
Pick a breed frame size, then drag the weight slider to watch the body reshape and the BCS gauge and calorie/weeks-to-goal stats update live. Toggle the rib-check overlay to see ribs fade under fat cover, and the ideal-weight ring to compare current size against target.
