⚕️ Veterinary Note: The Body Condition Score is the gold-standard method used by veterinarians worldwide. This tool uses the standard 9-point BCS scale. Always consult your vet before making significant changes to your pet's diet or exercise routine.
How the BCS Calculator works
📏
What is BCS? Body Condition Score (BCS) is a 9-point scale used by vets to assess fat coverage. It's more reliable than weight alone because it accounts for breed and frame size.

How to check. Run your fingers along your pet's ribcage. Ribs should be easily felt but not visibly protruding. From above, you should see a visible waist. From the side, there should be an abdominal tuck.
🎯
Ideal is BCS 4–5. A score of 4 or 5 out of 9 means your pet is at a healthy weight. Ribs easily palpated, waist visible from above, moderate abdominal tuck.
📊
Target weight formula. If your pet is overweight, their ideal weight ≈ current weight ÷ (1 + (BCS − 5) × 0.1). For underweight: ideal weight ≈ current weight ÷ (1 − (5 − BCS) × 0.1).
💧 How much water does your pet need?
Now that you know your pet's condition score, calculate their ideal daily water intake.
