Feeding an Overweight Dog — Weight Loss Diet Guide

Use body condition scoring (BCS) on a 1–9 scale. A score of 4–5 is ideal: you can feel ribs with light pressure but not see them, there's a visible waist when viewed from above, and an abdominal tuck when viewed from the side. A BCS of 6–7 is overweight; 8–9 is obese. If you can't feel ribs without pressing firmly, your dog is overweight. Your veterinarian can help you assess body condition and set a target weight.

For weight loss, feed 80% of the calories needed for your dog's target weight (not current weight). For example, if your 80-lb dog should weigh 65 lbs, calculate the maintenance calories for a 65-lb dog (roughly 1,100 kcal), then feed 80% of that (about 880 kcal). Aim for 1–2% body weight loss per week — faster loss can cause muscle wasting. Weigh monthly and adjust.

Simply feeding less of a regular food can leave your dog hungry and nutritionally deficient. Weight management formulas are designed to be lower in calories and fat while maintaining adequate protein, fiber, and micronutrients. They typically include higher fiber for satiety and L-carnitine to support fat metabolism. Ask your vet about prescription weight-loss foods for severely obese dogs.

Replace commercial treats with baby carrots (4 cal each), green beans (15 cal per 1/2 cup), ice cubes, frozen blueberries (1 cal each), apple slices without seeds (19 cal per slice), air-popped popcorn without butter, or small pieces of cooked chicken breast. Always factor treats into the daily calorie total — treats should be ≤10% of daily intake.
