12 Best Low-Calorie Dog Treats: Healthy Rewards Without the Weight Gain

Treats are one of the great joys of dog ownership — and one of the most common causes of unnoticed weight gain. Most commercial dog treats are far more calorie-dense than owners realise, and the habit of giving several throughout the day adds up to a meaningful calorie surplus that quietly pushes dogs toward overweight territory. The solution is not to stop giving treats — it is to choose smarter ones. Here are 12 of the best low-calorie treats for dogs, covering both natural whole food options and quality commercial products.

Why Low-Calorie Treats Matter

Treats should make up no more than 10% of a dog's total daily calorie intake. For a 10 kg dog needing around 500 calories per day, that means a maximum of 50 treat calories daily. A single commercial biscuit treat can contain 30 to 50 calories. Give three or four across the day and you have already used the entire treat allowance — or exceeded it. Switching to low-calorie alternatives allows you to reward, train, and bond with your dog more frequently without compromising their daily calorie budget or their weight management goals.

12 Best Low-Calorie Dog Treats

1. Carrot Sticks

Carrots are arguably the single best low-calorie treat for dogs and are recommended by veterinarians and nutritionists worldwide. A medium carrot contains approximately 25 calories, is rich in beta-carotene, fibre, and vitamins, and provides a satisfying crunch that many dogs love. Raw carrots also help clean teeth naturally as dogs chew them. They can be served raw, cooked, or frozen — frozen carrot sticks are particularly popular with dogs and make an excellent cooling treat in warm weather. Carrots are safe for almost all dogs and can be given generously without significant caloric impact.

2. Cucumber Slices

Cucumber is one of the lowest-calorie foods you can give a dog. A few slices contain barely 5 to 8 calories while providing hydration, vitamin K, and a refreshing crunch. Cucumber is particularly excellent for overweight dogs because the volume to calorie ratio is extraordinarily favourable — your dog gets a genuinely satisfying amount of food for almost no caloric cost. Serve plain without seasoning and remove the skin if your dog has a sensitive stomach.

3. Blueberries

Blueberries are a genuine superfood for dogs. A small handful of 10 blueberries contains only around 8 calories while delivering impressive levels of antioxidants, vitamins C and K, and fibre. The antioxidants in blueberries support immune function and have been shown to support cognitive health in senior dogs. Their small size makes them perfect for training treats where many individual rewards are needed in a short session. Most dogs love them and they can be served fresh or frozen.

4. Watermelon Pieces

Watermelon is a hydrating, refreshing, and genuinely low-calorie treat that most dogs enjoy enormously. A 100g serving contains only around 30 calories and provides vitamins A, B6, and C along with significant hydration from its high water content. Always remove the seeds and rind before serving — the seeds can cause digestive upset and the rind is difficult for dogs to digest. Frozen watermelon cubes are an excellent summer treat that provides hydration alongside the caloric benefit.

5. Apple Slices

Apple slices are a popular and nutritious low-calorie treat containing approximately 10 to 15 calories per slice. They provide vitamin C, vitamin A, and fibre, and the firm texture helps clean teeth. Always remove the seeds and core before giving apple to your dog — apple seeds contain trace amounts of cyanide that can be harmful in quantity, and the core is a choking hazard. Serve in thin slices and limit to a few pieces per day due to the natural sugar content.

6. Cooked Chicken Breast

Plain cooked chicken breast is one of the most effective training treats available, combining extremely high palatability with relatively low calorie density compared to commercial treats. A small 10g piece of cooked chicken breast contains approximately 11 calories and provides high-quality protein that supports muscle maintenance. It is especially useful for training high-value behaviours where your dog needs a particularly motivating reward. Always serve plain with no seasoning, oils, or sauces, and ensure it is fully cooked with no bones.

7. Green Beans

Plain green beans are an excellent low-calorie treat that many dogs enjoy. A 100g serving contains only around 31 calories while providing a good source of fibre, vitamins C and K, and manganese. Green beans are particularly popular as a treat substitute for overweight dogs because their bulk and fibre content provide a satisfying sense of fullness at minimal caloric cost. They can be served raw, steamed, or frozen. Always serve plain with no added salt, butter, or seasonings.

8. Cooked Sweet Potato Pieces

Small pieces of plain cooked sweet potato are a nutritious, moderately low-calorie treat that dogs tend to love. A 30g piece contains approximately 25 to 30 calories and provides beta-carotene, fibre, and vitamins B6 and C. Dehydrated sweet potato chews make an excellent commercial-style treat with a satisfying texture and chew time that keeps dogs occupied. Always serve plain with no added butter, sugar, or spices. Due to its natural sugar content, sweet potato should be given in moderate quantities for overweight dogs.

9. Plain Rice Cakes

Plain unsalted rice cakes are a surprisingly effective low-calorie treat for dogs. A single small rice cake contains approximately 35 calories and provides a satisfying crunch that many dogs enjoy. They are particularly useful as a treat for dogs with food sensitivities, as they are free from common allergens. Always choose completely plain varieties with no added flavourings, salt, or toppings. Break into smaller pieces to extend the treat duration and reduce the caloric impact of each piece.

10. Frozen Plain Yoghurt Drops

Small frozen drops of plain, unsweetened yoghurt make an excellent low-calorie treat, particularly for dogs that enjoy dairy products. Plain low-fat yoghurt contains approximately 10 to 15 calories per tablespoon and provides beneficial probiotics that support gut health. Freeze small drops on a baking sheet for a ready-made treat supply. Always use plain, unsweetened yoghurt with no artificial sweeteners — particularly xylitol, which is extremely toxic to dogs. Check that your dog tolerates dairy before introducing yoghurt treats, as some dogs are lactose intolerant.

11. Cooked Egg White Pieces

Plain cooked egg whites are an exceptionally high-protein, low-calorie treat option. A single cooked egg white contains only approximately 17 calories while providing around 4 grams of high-quality protein. This makes egg whites one of the best protein-to-calorie ratio treats available for dogs on calorie-controlled diets. Always serve fully cooked — raw egg whites contain avidin which interferes with biotin absorption. Serve plain with no oil, butter, or seasoning. Cut into small pieces for training use.

12. Commercial Low-Calorie Training Treats

When natural whole food treats are not practical — particularly for training sessions requiring many rapid rewards — quality commercial low-calorie training treats are an excellent alternative. Look for products with fewer than 5 calories per treat, a named animal protein as the first ingredient, no artificial colours, flavours, or preservatives, and a small size suitable for training use. Many quality brands offer specifically formulated low-calorie training treats that are highly palatable, easy to carry, and precisely portioned. Always count commercial treats in your dog's daily calorie total regardless of how low-calorie they claim to be.

Foods to Avoid as Treats

Not all human foods that seem like healthy treat options are safe for dogs. Never give grapes or raisins — toxic to dogs and capable of causing sudden kidney failure. Avoid onions and garlic in any form. Never give chocolate, macadamia nuts, or any products containing xylitol. Avoid high-sodium foods like processed cheese or deli meat. And be cautious with high-fat foods like peanut butter — while safe in small amounts for most dogs, it is very calorie-dense and some brands contain xylitol. Always check the ingredient label of any human food before giving it as a treat.

How to Count Treat Calories in Your Dog's Daily Total

The most important habit when using any treats — low-calorie or otherwise — is to count them as part of your dog's total daily calorie intake. If your dog's daily calorie target is 500 calories and treats account for 50, their main meals should total 450. This adjustment is simple but makes the difference between effective weight management and gradual, unnoticed weight gain. The FurrFit Quiz calculates your dog's personalised daily calorie target and can help you understand exactly how much room you have for treats within a balanced daily nutrition plan.

Final Thoughts

Low-calorie treats allow you to reward, train, and bond with your dog as often as you like without compromising their health or weight management goals. Start with whole food options like carrots, cucumber, and blueberries for maximum nutritional value at minimal caloric cost. Use cooked chicken breast or commercial training treats for high-value training rewards. And always count treat calories as part of your dog's daily total.
