The 18 Best Low Fat Dog Foods of 2025: Vet-Approved

This content was reviewed and fact-checked by veterinarian Dr. Sandra Tashkovska, DVM.

Every extra pound your dog carries is another strain on their heart, another ache in their joints, and another step closer to health problems you never want to face. The right low-fat dog food can mean the difference between a few more good years together or heartbreak too soon. Yet, many dog owners unknowingly pick “low-fat” formulas that are packed with fillers and barely better than regular kibble. So, how do you tell a truly healthy low-fat dog food from one that’s just clever marketing? In this guide, we will reveal the best low-fat dog foods and what to look for when selecting them.

What Is Considered a Low-Fat Dog Diet?

​A low-fat dog diet is typically defined as one containing less than 10% fat on a dry matter basis (DMB), or less than 17% of calories from fat, to be considered low-fat. Veterinarians and pet nutritionists commonly use this threshold to manage conditions like pancreatitis, obesity, hyperlipidemia, and other fat-sensitive health issues. Some veterinary diets, designed for dogs with pancreatitis, can have levels as low as 4% DMB.^[1]

How The Best Low-Fat Dog Food Can Help

According to the latest research, the best low-fat dog food can be beneficial for pets suffering from certain health conditions, like:

Always consult your veterinarian before making changes to your dog’s diet. Alternatively, you can receive personalized nutritional guidance from an online registered vet nutritionist through platforms like Vetster. You can also chat with an online vet to determine whether a low-fat diet is appropriate for your dog’s age, breed, and specific health conditions. In addition, at-home dog gut health tests can offer insight into your dog’s microbiome, helping identify digestive imbalances that may benefit from a lower fat intake. Likewise, at-home dog food allergy tests can pinpoint potential sensitivities that might be contributing to gastrointestinal issues, making it easier to select a low-fat formula that fully supports their digestive and overall health.

Best Overall Low Fat Dog Food

Flavor: Chicken

Protein: 30.8%

Fat: 11%

Fiber: 7.7%

Diet: AAFCO | Human-grade

Why we recommended it: Ollie Chicken Dish With Carrots recipe uses human-grade ingredients, minimal processing, and vet-formulated recipes. Unlike many low-fat kibbles that rely on fillers or artificial additives, this fresh food uses whole ingredients like chicken, chicken livers, carrots, and spinach to deliver essential nutrients without empty calories. It’s naturally lower in calories and fat compared to most commercial dog foods, yet rich in protein to help maintain lean muscle mass during weight loss. The pre-portioned delivery and personalized model also make calorie control easy—no need to second-guess serving sizes.

What sets it apart from competitors: Ollie’s meals are gently cooked and delivered fresh, preserving more nutrients, bioavailability, and flavor than regular kibble. Its lower calorie content compared to other Ollie recipes makes it especially helpful for weight management.

Best Low Fat Dry Dog Food

Flavor: Chicken & whitefish

Protein: 29.5%

Fat: 8.5%

Fiber: 10%

Diet: AAFCO | Human-grade

Why we recommended it: Open Farm’s Healthy Weight recipe combines lean proteins with a low-fat, high-fiber profile that supports healthy digestion and satiety, important for fat management. Unlike many standard “diet” kibbles, it avoids empty fillers and instead relies on nutrient-dense ingredients, such as pumpkin, coconut oil, and legumes, to provide balanced energy. It includes L-carnitine, which aids fat metabolism, while prebiotic fiber and fructooligosaccharides promote digestive health and beneficial gut bacteria. We love the brand’s commitment to transparency, ethical sourcing, and sustainability.

What sets it apart from competitors: Every ingredient is 100% traceable to its geographic origin, and the brand uses humanely raised, G.A.P.-certified chicken and Ocean Wise-recommended wild-caught whitefish. It also avoids rendered meat meals, artificial preservatives, and fillers, focusing instead on whole, non-GMO ingredients. The company’s environmental efforts, such as recyclable packaging through Terracycle, further distinguish it from other brands.

Best Low Fat Dog Food For Pancreatitis

Flavor: Turkey & beef

Protein: 45% Dm

Fat: 14% DM | 3% As fed

Fiber: 27% Dm

Diet: AAFCO | Human-grade

Why we recommended it: Raised Right’s Pancreatic Support meets the strict dietary needs of dogs diagnosed with pancreatitis without sacrificing ingredient quality. With exceptionally low fat levels and simple, clean ingredients, it helps minimize pancreatic flare-ups while providing complete and balanced nutrition formulated by veterinarians. The recipes are lab-tested for safety and nutritional adequacy, meeting AAFCO standards for adult maintenance. Raised Right’s commitment to ingredient transparency, batch testing, and omission of unnecessary fillers and preservatives sets a high bar for quality and safety. Both the beef and turkey pancreatic support recipes contain fat levels as low as 3 to 7% (as-fed) and carbohydrates of 2 to 4% (as-fed), making them well-suited for dogs with pancreatitis.

What sets it apart from competitors: Raised Right uses whole, human-grade ingredients (USDA-certified meats and organic vegetables) you can recognize—no rendered meals, preservatives, or fillers. It’s lightly cooked, rather than extruded, which retains more nutrients and makes it easier for sensitive digestive systems to process.

Best Prescription Low Fat Dog Food

Flavor: Chicken

Protein: 26%

Fat: 7.5%

Fiber: 1.8%

Diet: AAFCO

Why we recommended it: Hill’s Prescription Diet i/d Low Fat Digestive Care is clinically proven to lower blood triglyceride levels, a key factor in managing pancreatitis and hyperlipidemia, a condition characterized by having abnormally high levels of lipids (fats) in the blood. Its low-fat profile reduces pancreatic strain while providing essential nutrients through highly digestible hydrolyzed chicken protein. The inclusion of ginger soothes the gastrointestinal tract, and omega-3 and omega-6 fatty acids promote skin and coat health, making it a holistic choice for sensitive dogs. The inclusion of ActivBiome+, a proprietary prebiotic blend, supports gut microbiome health, improving stool quality and nutrient absorption, which is critical for dogs with chronic digestive issues.

What sets it apart from competitors: S+OXSHIELD technology helps prevent kidney stones and urinary crystals, addressing common comorbidities in patients with pancreatic disease and obese dogs.

It’s crafted with wild-caught whitefish, a lean protein that’s gentle on digestion. The inclusion of a proprietary GI Health blend, which includes prebiotics and dietary fiber, supports gut microbiome balance. Meanwhile, Omega-3 fatty acids (DHA and EPA) reduce inflammation and improve skin and coat health. Veterinarian-formulated and free from artificial additives, it’s crafted for dogs needing a low-fat diet and digestive reassurance. Owners report fewer episodes of vomiting or diarrhea, even in dogs with chronic gastrointestinal issues.

What sets it apart from competitors: SquarePet’s formula prioritizes sustainable, MSC-certified fish and avoids poultry and beef allergens common in sensitive stomach diets. Its dual focus on low-fat nutrition and prebiotic support distinguishes it from competitors.

Flavor: Chicken

Protein: 30%

Fat: 10%

Fiber: 10%

Diet: AAFCO

Why we recommended it: Dr. Tim’s Metabolite Formula is one of the few low-fat options that directly targets fat metabolism through a science-backed nutritional profile. It includes ingredients like L-carnitine to support energy conversion, and it’s carefully balanced with a higher protein-to-fat ratio to help older dogs maintain lean body mass. The recipe also features Omega-3 fatty acids, L-carnitine, and antioxidants, which are important for joint, brain, and fat metabolism, as well as reducing inflammation and supporting immune health in seniors. The inclusion of prebiotics (chicory root) and probiotics (Bacillus coagulans) promotes gut health, addressing common digestive concerns in seniors. Dr. Tim’s uses high-quality meat concentrates and functional fibers, including psyllium husk and beet pulp, to balance satiety and nutrient absorption.

What sets it apart from competitors: This formula actively supports metabolic function through patented ingredients, including DMG (dimethylglycine) and prebiotics, which promote gut health. The kibble is also designed to be easily digestible, which is crucial for older dogs with more sensitive systems.

Best Low Fat Dog Food for Small Breeds

Flavor: Chicken

Protein: 29%

Fat: 10%

Fiber: 3.9 %

Diet: AAFCO

Why we recommended it: Eukanuba Fit Body Small Breed stands out for offering a low-fat formula with a high protein content that supports muscle retention while reducing fat. The kibble is specifically shaped for smaller mouths, making it easier to chew and digest. Additionally, it contains L-carnitine—a nutrient that aids in converting fat into energy, which is crucial for dogs that need to slim down without compromising their strength or stamina. It’s particularly beneficial for breeds like Dachshunds, Pomeranians, and Chihuahuas that gain weight easily and have faster metabolisms compared to larger breeds.

What sets it apart from competitors: It’s specifically calibrated for the metabolism and energy needs of small breeds. It also includes added DHA and antioxidants for brain and immune health. The addition of higher levels of glucosamine and chondroitin sulfate (over 50% more than the standard formula) provides enhanced joint support, which is particularly crucial for small breeds that carry extra weight. 

Best Low Fat Dog Food for Large Breeds

Flavor: Chicken & rice

Protein: 27%

Fat: 9.5%

Fiber: 5.5%

Diet: AAFCO

Why we recommended it: Purina Pro Plan’s Large Breed Weight Management formula strikes an effective balance between calorie control and optimal nutrition support for large breeds. Its well-balanced macronutrients help retain lean muscle while promoting fat loss, making it ideal for breeds like Labradors, Great Danes, and Mastiffs—dogs that are prone to obesity but still require robust joint support. The formula is also fortified with glucosamine and EPA, omega-3 fatty acids that support joint function, which is especially important for heavier dogs susceptible to hip and elbow issues. Antioxidants and live probiotics (600 million CFU/lb) are added to support gut health and immune function, critical for aging large breeds.

What sets it apart from competitors: Breed-specific focus tailored to meet the metabolic and structural demands of large breeds. Wheat bran and natural fiber sources aid digestion and help curb hunger, addressing the “always hungry” feedback often associated with diet foods.

Best Low Fat Dog Food for Puppies

Flavor: Fish, chicken, beef & more

Protein: 38.8%

Fat: 11.1%

Fiber: 16.6%

Diet: AAFCO

It’s a vet-recommended option, carefully balanced to meet AAFCO nutrient profiles for puppy growth. The moisture-rich formula promotes hydration and helps dogs feel full on fewer calories—something most dry kibble options can’t offer for weight-conscious pups. The use of wild-caught white fish (cod, pollock, haddock) provides easily digestible protein and a rich supply of omega-3 fatty acids, which promote skin and coat health. High calcium and phosphorus levels meet the nutritional needs of growing puppies, supporting the development of strong bones and tissues.

What sets it apart from competitors: The recipe is hand-prepared in open kitchens using 100% human-grade ingredients and contains no additives, preservatives, or growth hormones, which appeals to owners seeking transparency and quality.

Fiber: 6%

Why we recommended it: Addiction’s Wild Kangaroo & Apples recipe is a rare find in the world of allergy-friendly diets that also support fat loss.

The formula is grain-free and enriched with antioxidant-rich fruits and vegetables, such as apples, spinach, and cranberries, to support immune and skin health.

Best Low Fat Wet Dog Food

Flavor: Venison, chicken, beef & more

Protein: 28.5%

Fat: 10.7%

Fiber: 1.4%

Diet: AAFCO

Why we recommended it: PetPlate’s Lean & Mean Venison offers a lean, high-protein profile that promotes fat loss while preserving lean muscle, crucial for healthy weight reduction. The wet, gently cooked format is more hydrating and palatable than dry food, which is a big plus for dogs with low water intake or those who tend to be finicky eaters. Portion-controlled containers make it easy for owners to serve exact calorie amounts without guesswork. This recipe utilizes USDA-inspected venison as its primary ingredient—a novel protein rarely found in mainstream dog foods, which reduces the risk of allergic reactions and makes it ideal for elimination diets. The inclusion of venison liver provides bioavailable vitamins, while apples, carrots, and sweet potatoes offer natural fiber and antioxidants to aid digestion.

What sets it apart from competitors: Prepared in USDA-approved kitchens with 100% human-grade ingredients, the recipe avoids artificial additives, fillers, and common allergens, such as soy and corn.

Each batch is also lab-tested for safety and nutritional adequacy, and the company shares full transparency around its formulations—something rarely matched in the veterinary diet space.
