Dog Weight Loss Planner
Create a personalized calorie and meal plan to help your dog reach a healthy weight safely, with week-by-week milestones and treat budgets.
How the Dog Weight Loss Planner Works
This planner uses the veterinary Resting Energy Requirement (RER) formula to calculate exactly how many calories your overweight dog needs each day to lose weight safely. The formula is RER = 70 x (target weight in kg)^0.75. For weight loss, veterinarians typically restrict calories to RER only, meaning no activity multiplier is applied. This creates a controlled calorie deficit that promotes steady fat loss without risking muscle wasting or nutrient deficiencies.
The safe weight loss rate for dogs is 1 to 2 percent of body weight per week. Losing weight faster can cause hepatic lipidosis (fatty liver disease) and lean muscle loss. Our planner generates a week-by-week timeline so you know exactly what to expect at each milestone along your dog's journey to a healthier weight.
Setting Up Your Dog's Diet Plan
Start by weighing your dog accurately. Home scales work well for small dogs. For larger dogs, weigh yourself first, then hold your dog and subtract. Your veterinarian can confirm the ideal target weight based on breed standards and body condition scoring. Once you have your calorie target, check your dog food label for the kcal per cup value. Divide daily calories by kcal per cup to get the exact portion size. Split this into two meals per day for better metabolism and hunger management.
Treats should never exceed 10 percent of your dog's daily calorie intake during a weight loss program. Many commercial treats contain 20 to 80 calories each, so even a few can derail progress. Low-calorie alternatives like baby carrots, green beans, blueberries, and ice cubes give your dog the reward experience without the calorie load.
Exercise and Monitoring During Weight Loss
Exercise supports weight loss by increasing daily calorie burn and preserving lean muscle mass. Start with the activity level your dog can handle comfortably. For overweight dogs, begin with 15 to 20 minute walks twice daily, then gradually increase duration and intensity each week. Swimming is an excellent low-impact option for dogs with joint issues. Weigh your dog weekly at the same time of day for consistent tracking. If weight is not decreasing after two weeks, reduce daily calories by 10 percent. If your dog loses more than 3 percent of body weight in a single week, increase food slightly. Always consult your veterinarian before starting a weight loss program, especially for dogs with diabetes, hypothyroidism, or other health conditions.
