What is a Body Condition Score (BCS)?

BCS is a 9-point scale used by veterinarians to assess a pet's body fat. A score of 4–5 is ideal. Scores below 3 indicate underweight; scores above 6 indicate overweight or obese.

How do I find my pet's ideal weight?

Your vet is the best source. As a general guide, a dog's ideal weight is when you can feel (but not see) their ribs, see a defined waist from above, and see a slight tuck behind the ribcage from the side.
