Body Condition Scoring

Body condition scoring is a system developed by vets to help you assess if your dog, cat or rabbit is the correct weight.

Just like people, dogs, cats and rabbits come in all shapes and sizes, and weight alone is not a good measure to see if your pet is healthy. By looking at your pet’s overall shape, and getting ‘hands on’, you can get a much better idea of whether your pet is doing well, needs to put weight on, or if they might be carrying a few extra kilograms. 

Body condition scores mainly involve looking at and feeling the ribs and waist, and guideline charts like those below can help you assess what you are seeing and place your pet on the body condition score scale.

Top tip

We asked Danielle, Registered Veterinary Nurse at Vets4Pets Corstorphine, for guidance on checking that your pet is a healthy weight.

"You should be able to feel your pets’ ribs without having to apply excessive pressure. Having to apply pressure would indicate the pet is overweight. If ribs are visible the pet may be underweight. The body score chart can be used to show if our pets are underweight, overweight or ideal weight. We aim for our pets to be a score of 4 or 5 on this scale. If you require help or find it difficult to maintain your pet at a healthy weight, then you can call your clinic and book in with a nurse for a consultation and additional help."
