Buyer’s Guide: Choosing the Best Low-Fat Dog Food
The amount of fat that a dog needs in their diet will vary depending on the individual dog. Young, highly active dogs can eat more fat than less active, older dogs that don’t move as much. Age, metabolism, activity level, and health status all factor into what each dog needs.

Why Is Fat Bad for Dogs?
Just like too much fat in a human’s diet can cause problems, the same is true for dogs. Obese dogs are at an increased risk of diabetes, pancreatitis, heart disease, and joint/mobility problems. This can shave years off their lifespan. Keeping your dog slim and healthy is one way to ensure that they live a long, happy life.
Why Choose Low-Fat Dog Food?
Diets with more than 20% fat are considered high fat and less healthy for your adult dog. Dog owners are encouraged to feed their dogs a low-fat diet to keep their pups as healthy as possible and avoid unintentional weight gain. Low-fat foods can also be helpful for dogs with certain health issues because they are usually lower in carbohydrates too. Dogs should have some fat in their diet, but it should take up no more than 10%–15% of the nutritional content. Fat content lower than 10% will help dogs lose weight without sacrificing nutrition.
No dog owner wants their dog to go hungry, though. With low-fat dog food, your dog is automatically getting fewer calories. This means you don’t have to give your dog less food to have them eat less fat and calories.
Before buying any new food for your dog, always consult your vet first to make sure you’re feeding them what they need for their age, health status, and activity level.
Conclusion
Our best overall choice for low-fat dog food is Solid Gold Fit & Fabulous Weight Control Dry Dog Food. It has a low-fat content of only 6.5%, along with probiotics for healthy digestion. For the best value, we like Iams ProActive Health Dry Dog Food. It has a 9% fat content and uses chicken as the first ingredient. Blue Buffalo Healthy Weight Dry Dog Food is our premium choice, with its LifeSource Bits of added nutrients. It also contains glucosamine and chondroitin for joint health. We hope that our reviews have helped you find a low-fat food that your dog loves.
