Best Grain-Free Dog Food: Top 7 Brands Most Recommended By Experts

Grain-free dog food has gained popularity among pet owners due to its perceived benefits for canine health. Some believe that grain-free diets can help alleviate allergies, digestive issues, and sensitivities, while others view them as a more natural and wholesome option for their furry companions. However, studies on the long-term effects of grain-free diets are still ongoing, and veterinarians recommend consulting with a professional before making a switch in your dog’s diet. With that in mind, we listed the top seven best grain-free dog food brands.

Why is it that some dog owners have gotten on board the grain-free hype train? There are some pretty convincing reasons. Here are the most often cited reasons as to why some owners are opting for a grain-free dog diet:

Digestive Advantages:

  • Improved Digestion: Grains, especially wheat, corn, and soy, can be difficult for some dogs to digest. This can lead to digestive issues like bloating, gas, and diarrhea. Grain-free food eliminates this potential source of discomfort, promoting smoother digestion and optimal gut health.
  • Reduced Allergic Reactions: Food allergies are common in dogs, with grains being a frequent culprit. Grain-free food minimizes the risk of allergic reactions, leading to less itching, scratching, and skin irritation.

Enhanced Energy Levels:

  • More Bioavailable Protein: Grain-free food often boasts a higher protein content compared to traditional kibble. This readily available protein translates into sustained energy levels, supporting your dog’s active lifestyle.
  • Improved Nutrient Absorption: The absence of grains allows for better absorption of essential nutrients like vitamins, minerals, and antioxidants. This boosts your dog’s immune system and overall health.

Weight Management:

  • Lower Carbohydrate Content: Grains are a significant source of carbohydrates, which can contribute to weight gain, especially in less active dogs. Grain-free food typically has lower carb content, promoting healthier weight management.
  • Increased Nutrient Density: Grain-free food often packs more protein and healthy fats per serving, keeping your dog feeling fuller for longer and reducing the urge to overeat.

Overall Health and Well-being:

  • Shinier Coat and Healthier Skin: Grain-free food can contribute to a shinier, healthier coat and reduced skin irritation due to improved digestion and nutrient absorption.
  • Increased Vitality: The combination of improved digestion, enhanced energy levels, and better nutrient absorption leads to a more vibrant and energetic dog.

Grain-free dog food has been heavily marketed in recent years, and some dog owners are simply drawn to the idea of feeding their dogs a grain-free diet. They may believe that grain-free dog food is healthier or more premium for their pooch. Our sources helped us learn about the best grain-free dog food brands to switch to for a heathy puppy.

  1. The headline of best grain free dog food should not be about just being grain free as that in itself does not relate to a biologically appropriate, highly nutritious food for dogs.
    This subject is about the kibble convenience and we won’t call that a food for dogs. As the Pet food industry in Australia goes highly unregulated, the ingredient profiles are very susceptible to additives, fillers, carbohydrates, rendered meats (roadkill or non human grade food groups), chemical antibiotics and the list goes on. The ingredient lists on the packaging do not list the full profiles of ingredients.
    Besides all of that, the process required to create kibble is extreme where very high temperatures are used around 280 to 350 degrees C to ensure no pathogens exist before it goes into an extrusion machine to make the kibble pellets. After that heat process, extrusion and cooling what health nutrients would be available in the kibble???
    Please do your research on that!
    If it was human grade foods, there would be no pathogens and therefore no extreme heat treating process required.

    As you can imagine, there’s a very strong movement growing in Australia and the US where people actually care about their pets and feed them biologically appropriately fresh food diets.

    Please don’t refer to Vets knowing anything about nutrition when one of the largest players in the kibble pet food market provide them with advice on products and training. (Hills)

    So, for me to see some nonsense, non scientific research on the values of kibble in a market loaded with this junk makes me wonder who you represent?

  2. You haven’t published my previous comments because it does not agree with your so called “expert” recommendations.
    Don’t ask for realistic comments if you don’t like the truth!

  3. Veterinarians have established that feeding your dog a grain free diet will result in heart damage leading to death. Dogs MUST have grain their diet. This is a widely known fact and your promoting a grain free diet with this article is not only scandalous but also irresponsible. Shame on you.
