Top 9 Best Grain Free Dog Foods 2020

One of the prevalent trends in human nutrition are grain-free diets. Some people have a gluten intolerance, a medical condition, or other reason they cannot have grain in their diets. The same has occurred with dogs. Grain-free dog foods have become a new buzz word in the pet food industry.

Are there benefits of grain-free dog food? If so, are they any better than dog foods that contain grain? In this article we’ll touch on the benefits of grain-free dog food, how to choose the best one, and some of our favorites.

Benefits of Grain Free Dog Food

Grain-free dog food offers some benefits, but that does not necessarily mean that they’re better than dog foods that contain grain. Through the course of their evolution, a dog’s metabolism has developed to digest complex carbohydrates such as grains. This stands in contrast to the common misconception that dogs cannot, quite literally, stomach them.

One benefit of a grain-free diet is that dogs with a grain sensitivity should not see any symptoms associated with that dietary condition. Dogs that have a grain allergy may experience any of the following symptoms:

  • Itchiness
  • Excessive hair loss
  • Sores and scabs
  • Inflammation of the skin
  • “Hot spots”
  • Bald patches

Typically a grain-free dog food will also contain more natural and better ingredients such as animal protein, animal meal, fruits, vegetables, and added vitamins and minerals. So if you find a grain-free dog food you like, check the ingredients. Chances are that it’s a great choice for your dog!

How to Choose the Best Grain Free Dog Food


Before we begin looking at some of the best grain-free dog foods on the market, let’s talk about how to select the best one for your pup. Put simply, some dog foods are better than others. Many cheaper brands contain fillers and other ingredients that can potentially be harmful to your dogs.

When reviewing the nutrition and ingredient information on dog food labels, keep in mind that the higher on the list an ingredient appear, the more of that ingredient appears in the food.

For instance, if you see animal protein at the beginning of the list, that means animal protein is a key ingredient in the dog food.

1. The Best Stuff to Look For

  • High animal protein content

Dogs are carnivores. Therefore, it’s important that animal protein makes up a large portion of dog food. Look for named animals like beef, chicken, lamb, rabbit, venison, buffalo, or duck. If the label fails to specify the animal protein, consider looking elsewhere. Would you feed yourself “meat” if you didn’t know the animal from which the meat originated?

  • Other animal protein meal

Animal protein meal is another term for the bones, connective tissues, meat, tissue, and other parts that have been processed and dried in the manufacturing process.

Why animal meal? Surprisingly, animal meal has more protein than animal meat alone. There’s an inverse relationship in the amount of protein and moisture in animal meat versus animal meal. Animal meat has more moisture and less protein. The opposite is true for animal meal.

  • Fruits and vegetables

Unprocessed foods such as fruits and vegetables offer a wealth of healthy vitamins, minerals, and nutrients to keep our canine companions happy!

2. The Not-So-Good Stuff to Look For

There are also some ingredients you should avoid in dog food as much as possible. Some dog foods contain fillers or artificial ingredients to add “fluff” to the dog food. Here are a few ingredients to keep an eye on.


  • Meat or Poultry By-Products

In general meat or poultry by-products are not as healthy as animal protein or other whole ingredients found in dog food. These tend to be cheaper ingredients as well. Avoid these if you can.

  • Artificial Sweeteners

Dogs love sweet things just as much as people do. If dogs eat food containing artificial sweeteners, they’re less likely to get the kind of protein and nutrients necessary to keep them happy and healthy.

  • Artificial Anything Else (Preservatives, Flavoring, Colors)

Just like human food, you should try to avoid dog food which contains preservatives, flavoring, or colors derived from artificial sources. They’re less likely to matter to your dog. Plus, there’s always a chance they could impact your pup’s digestion system or cause other issues down the road.

If you’re concerned about the shelf life of your dog food, you can always check the “best by” date.

  • Fillers

You’ll want to avoid dog food brands that contain fillers such as corn bran, cereal by-products, and other items that may fill a dog’s stomach but may not have much nutritional value.
