Weight gain in dogs is not uncommon, and many pets gradually put on extra pounds over time. Beyond being a cosmetic concern, obesity in dogs can signal serious health issues such as joint problems, heart and lung conditions, and even a shortened lifespan. To help your dog shed weight, it's essential to reduce calorie intake and increase physical activity.
Steps
Reduce Calorie Intake

Consult a Veterinarian. Before starting any diet plan for your dog, seek advice from a veterinarian. Many clinics offer weight-loss programs for dogs, where you can bring your pet for regular weigh-ins and receive detailed guidance on daily food portions. With a long-term weight-loss plan, sustainable goals, and emotional support, you can provide your dog with an effective and successful diet. Your vet may recommend one of the following diets:
- High-fiber/low-fat diet: This diet includes fiber that expands in the stomach, making your dog feel full. Choose foods with clear feeding guidelines based on the target weight loss.
- Metabolism-boosting diet: This advanced diet incorporates technology to enhance your dog's metabolic rate, helping burn calories and promote weight loss.

Determine the daily food portion for your dog. Pay close attention to how much your dog has been eating recently. If your dog eats twice a day, you can weigh the total amount of food for both meals to calculate the daily intake. However, if your dog has constant access to food, this process becomes more challenging. Additionally, it can be difficult to know how much to reduce their food. In such cases, refer to the feeding guidelines on the food packaging for weight loss recommendations.
- Product packaging typically lists food amounts based on weight for most dogs. For example, 300-350 g of food per day. To help your dog lose weight, opt for the lower end, such as under 300 g.

Reduce your dog's food intake. Once you know how much your dog eats daily, cut their food by 5-10%. For instance, if your dog consumes 300 g of dry food daily (10% of 300 g is 30 g), reduce it to 270 g. Maintain this reduced portion for 1-2 weeks, then weigh your dog. If successful, your dog's weight should decrease. If not, reduce the food by another 5-10% and monitor for another 1-2 weeks.
- Don’t feel discouraged if your dog seems hungrier or their portions look smaller. This is a common concern when starting a diet. If unsure, consult your vet for a prescribed weight-loss plan.

Offer healthy treats occasionally. While reducing food and increasing exercise, positive reinforcement is key. Healthy treats can serve as rewards. Ensure the snacks are nutritious and satisfying. Here are some options:
- Bran or grated vegetables mixed into their food
- Raw green beans or snap peas
- Apples (in moderation)
- Bananas (in moderation)

Encourage activity for food. Teach your dog to work for their meals instead of eating from a bowl. Use puzzle toys or food-dispensing games where your dog must move pieces or roll a ball to release food. This engages them physically and mentally, preventing boredom during dieting. Shift their focus from food to fun activities.
- Training is another effective way to keep your dog active and entertained. Since training relies on rewards, use small portions of their meal as incentives during sessions.

Monitor weight loss progress. Weigh your dog every 1-2 weeks to track their progress. This helps evaluate the effectiveness of the diet and routine. If your dog isn’t losing weight, reassess the plan. Ensure the goals are realistic and nutritionally balanced. Avoid expecting rapid weight loss; slow and steady progress is more sustainable. Aim for no more than 120 g per week for small dogs or 0.5 kg for larger breeds.
- If you can’t weigh a large dog, use a measuring tape. Measure a specific body part, such as the chest or waist, and mark the highest point for consistent tracking.
Exercising Your Dog

Establish an exercise routine. It’s not just about starting exercise; you need to create a consistent routine tailored for your dog. Overweight dogs unfamiliar with activity should gradually adapt to exercise. Suddenly taking your dog on long walks daily might cause joint pain or injuries instead of aiding weight loss. Consult your vet to determine the appropriate starting activity level.
- For less active dogs, place food a short distance away and encourage them to fetch it. Simple games like rolling a ball and rewarding them with a small portion of their meal when they retrieve it can also help.

Take your dog on moderate walks. Gentle walks are ideal for overweight dogs. Use a leash and walk at a comfortable pace, paying attention to the duration and distance. Gradually increase the walking time by 5 minutes each week.
- For example, if your dog can only walk for 5 minutes in the first week, extend it to 10 minutes in the second week, 15 minutes in the third, and so on. If your dog can only handle short walks, take them out 2-3 times daily to build endurance and aid weight loss.
- Ensure your dog is actively walking and not just sniffing around during the walk.

Increase exercise intensity. Gradually extend the duration, frequency, and intensity of walks to enhance weight loss and overall health. Incorporate other activities to keep your dog engaged. Once your dog is comfortable walking, try these exercises:
- Cycling: As your dog’s stamina improves, let them run alongside your bike. This benefits both you and your dog, but ensure safety for everyone involved.
- Swimming: Start with short swims and gradually increase the time. Swimming is excellent for overweight dogs as it’s low-impact and easy on the joints. Use a life jacket to prevent fatigue or drowning risks.
- Interactive toys: Use toys like balls, frisbees, or stuffed animals to encourage activity. Toss their favorite toy repeatedly until they tire. If you have back pain, consider a toy launcher for easier retrieval.

Motivate your dog positively. Praise your dog verbally and physically before, during, and after exercise. For example, pet them, scratch their ears, and say "Good dog!" Positive reinforcement keeps your dog excited about exercising. Linking rewards to exercise makes it more enjoyable and motivating.
- Be patient with the exercise program. It may take months for your dog to reach their weight loss goals, but consistent and structured exercise will yield results.
