Weight Dog - Body Condition Scoring (BCS) in Dogs

Is my dog too fat or too skinny? A guide to body condition scoring in dogs

Have you ever wondered if your pet needs feeding up, or if you need to cut out the treats? When vets assess your dog’s weight they are not just looking at the number on the scales but also assessing something called their Body Condition Score (BCS). Just like humans there is no ‘one size fits all’ ideal weight for our pets and even within breeds there is a lot of normal variation (which is why breed averages are not very helpful). Learning to body condition score your dog will help keep them healthy at all life stages. Here we share our tips and advice.

What is body condition scoring?

A body condition score chart gives you a silhouette and a list of characteristics to look for. If you have a very fluffy pet, think of how they look in the bath when their hair is all wet.

The four main things we assess when deciding on overall body condition are:

  • Ability to feel ribs, lower spine and bony prominences

  • Ability to see a ‘waist’ - tucking in of the abdomen after the ribcage when looking at your dog from above

  • Ability to see an ‘abdominal tuck’ - tucking up (upward slant) of the abdomen after the ribcage when looking at your dog from the side.

  • Presence of fat deposits


A body condition score is the score given to your dog (out of 9) depending on which of the above features you can see and feel.

Make sure to run your hands over your dog to assess the amount of fat you can feel over the ribs and spine as well as look at your dog’s silhouette from above and from the side.
