Frequently Asked Questions
What is a body condition score (BCS) for dogs?
BCS is a standardised 9-point scale used by vets to assess a dog's body fat. A score of 4–5 is ideal. Below 4 indicates underweight; above 6 indicates overweight. It's considered more accurate than weight alone because it accounts for muscle mass and frame size.
How do I check my dog's body condition at home?
Run your hands along your dog's ribcage. You should feel ribs easily with light pressure — like the backs of your fingers on your hand. Look from above for a visible waist. Look from the side for a slight abdominal tuck. No waist or no tuck usually indicates excess weight.
My dog is at their "ideal" weight but the vet says they're overweight — why?
Weight is breed and size specific, but BCS is universal. A dog can be at their breed's "average" weight but still carry excess fat — especially if they've lost muscle mass. BCS is a more meaningful measure because it looks at actual body composition, not just the number on the scale.
How quickly should an overweight dog lose weight?
Safely 1–2% of body weight per week maximum. Faster than this causes muscle loss and nutritional deficiencies. For a 60lb dog, that's 0.6–1.2lbs per week. Work with your vet — they may recommend a prescription weight loss food or a calorie-restricted plan based on your dog's specific needs.
