Top Picks for the Best Dog Foods to Help Your Pup Reach a Healthy Weight

Low fat dog foods can be beneficial for pets with health conditions such as pancreatitis, obesity, and inflammatory bowel disease (IBD). However, finding a quality low fat dog food can be challenging because pet food companies tend to reduce fat by incorporating less meat, resulting in low protein and high carbohydrate content. To assist with selecting a suitable low fat dog food, our research team has identified products that meet the following criteria: well below-average fat content, reasonable protein levels, and a rating of 4 stars or higher. To meet these requirements, low fat dog foods may contain less meat and more plant-based protein.

How to determine the best food for your dog

When it comes to ensuring your dog’s food promotes good health, two primary factors come into play: nutritional completeness and balance, as well as appropriate portion sizes based on your dog’s weight and size. According to Dr. Megan Shepherd, a certified veterinary nutritionist and owner of Veterinary Clinical Nutrition, PLLC, it’s essential to look beyond just the label when selecting your pet’s food.

While the label can provide important information, such as the AAFCO statement indicating the food’s suitability for specific life stages and how it’s substantiated, there are other critical factors to consider. The World Small Animal Veterinary Association’s Global Nutrition Guidelines recommend researching the brand to determine who formulates and manufactures the product and whether they regularly analyze their finished products for nutrient content, pathogens, and other harmful substances.

Dr. Brian Roberts, a board-certified veterinarian and regional medical director for VCA Animal Hospitals in the Mid-Atlantic region, stresses the importance of brands that invest in research and employ board-certified veterinary nutritionists. To help you navigate the world of high-quality dog food, we’ve outlined some key considerations recommended by experts.


What is the number one healthiest dog food? 

There is no single healthiest dog food. Generally, healthy foods meet the AAFCO’s nutritional requirements for complete and balanced nutrition and contain only high-quality ingredients. However, no individual dog food can be considered the healthiest. 

What is the best dog food recommended by vets?

Given the wide variety of dog foods and the different health needs they cater to, there’s no one best dog food that veterinarians recommend. A vet will consider many factors, such as a dog’s overall health status, life stage, and lifestyle, to determine which dog food is most appropriate for an individual dog. 

What is the best food I can feed my dog?

Every dog is different, so there’s no end-all-be-all, best dog food. Shepherd shares a few indications that your dog is eating a food that’s right for them: 1) maintaining a healthy weight (body condition score of 4 or 5 out of 9, normal muscle condition score); 2) having normal poop (easy to pick up and not overly firm); 3) no vomiting between meals; 4) having healthy skin and coat (no dry, flaky skin); and 5) achieving appropriate growth if they’re a puppy. The best food for your dog will also be one they enjoy eating, which can take some trial and error. 

What is human-grade dog food?

If a dog food says it’s “human-grade,” it means the finished food is processed, handled, stored, and transported according to the manufacturing practices for human foods. This process must be meticulously documented, and the label should clearly mention the food is for dogs. In his years of experience, Swanson has tested a few human-grade pet foods in his lab. “While I don’t have a strong preference to any one type or brand of diet, I can say that the human-grade foods I have had experience with are highly palatable, highly digestible, and resulted in a low volume of stool that allowed for easy clean up,” he says.

Do dogs need grain-free food?

No. No. Despite pet food marketing suggesting that grain-free foods are better for dogs than grain-containing foods, no scientific evidence supports this claim. “Animals require nutrients, not ingredients,” says Swanson. Concern over grain-free dog foods began in 2018, when several veterinary cardiologists noticed unusually high numbers of non-genetic dilated cardiomyopathy (DCM) in dogs. As of November 2022, approximately 1,400 cases of DCM in dogs have been reported to the FDA, up from several hundred cases since 2018. In its latest update, the FDA notes that this increase in reported cases does not indicate a definitive link between grain-free dogs and DCM in dogs. The investigation is ongoing.

Are meat byproducts bad?

Not necessarily. The AAFCO defines byproducts as “secondary products produced in addition to the principal product.” Pet food advertising often portrays byproducts as undesirable and unappetizing, but properly processed byproducts are safe and nutritious. For example, liver is a byproduct full of vitamins and minerals that are good for pets. Before meat byproducts can be used in dry or canned pet food, they must be heat-treated and undergo additional processing to eliminate all disease-causing bacteria. Sometimes pet food manufacturing facilities render byproducts, meaning that the byproducts are cooked to kill disease-causing bacteria. On a dog food label, you will see a meat byproduct listed as “byproduct” or “meal.” This indicates that the meat ingredient has undergone additional processing and is safe for your dog to eat.

How often should I feed my dog?

Several factors determine how often you should feed your dog, such as their life stage, health status, and the food’s palatability. Your veterinarian can provide recommendations for your dog to ensure proper nutrition and calorie intake. “The most important thing is to feed a complete and balanced diet and provide controlled amounts of food,” Swanson says. “Monitor your dog’s body weight and body condition over time and adjust feeding amounts so that a healthy body weight is maintained.” Because dogs aren’t known for their portion control, don’t leave food out for all-day eating. Treats should comprise no more than 10% of a dog’s daily caloric intake. Your veterinarian can help you determine how many “treat” calories your dog can have daily.
