Pros & Cons of Grain-Free Diets For Dogs

Before we dive into the benefits or drawbacks of grain-free dog foods it is first best to examine exactly what it is and how it differs from traditional and low-fat dog foods currently found on the market.

What’s a Grain-Free Dog Food?

Quite simply, grain-free dog foods remove any grain-based ingredient from their recipe. A grain-free diet for dogs aims to move more in line with what dogs would have eaten before humans stepped in and began to mass-produce the type of dog food we are now so used to seeing stacked on our shelves. By removing grain, compared to typical dog food, a grain-free diet will attempt to insert more meat protein and digestible animal fats into your dog’s diet.

Now you hopefully have a better understanding of what grain-free dog food is, it is time to try and clear up some of the myths attached to this type of dog diet. There is still some divide as to how beneficial grain-free dog foods are but this guide will attempt to answer your questions and leave you feeling far more confident about what you’re feeding your pet.

Benefits of Grain-Free Diet for Your Dog

With grain-free pet foods growing in popularity you may be asking the question of why. What is it that is making a huge number of pet owners switch to a grain-free diet and what exactly are the core benefits of making the change?

Ultimately we all want what is best for our pup and below we have outlined the four main reasons why switching to a grain-free diet could be advantageous for your dog — a grain-free dog food helps with:

  • reducing the risk of allergic reactions to wheat, corn, or other grains typically found in dog food
  • getting closer to a meat-based diet that dogs would have evolved within the wild
  • avoiding cheap carbohydrate-based fillers and low-quality alternative dog foods
  • improving your dog’s digestion thanks to healthy fats and quality proteins

These benefits are very much centered on improving the overall health of your dog by moving to a more natural and holistic approach to their food. As with human diets that avoid processed or ‘fad’ foods that we would have had no exposure to in the wild, you can view your dog’s diet is very much the same way.

However, even with the popularity of grain-free dog food continuing to grow, it is extremely important to make the decision based on your own dog’s needs — simply because what might be the right approach to dieting for one dog may not necessarily be true for the next one.

For example, if you own a specific breed with unique needs such as a bully breed, try to have a diet adapted to them, with for example the best dog food for Pitbulls: higher in proteins and fat, much lower in carbs.

Are Grains Bad for All Dogs?

Although you may have read the above section and decided emphatically that making the switch to a grain-free diet is the right thing to do, it is important to consider both sides of the debate. To help you make a well-rounded decision here, we will consider a number of drawbacks to grain-free dog foods and why you need to make the decision based on the entire corpus of information, and not just what is the hypest dog diet currently.

Many of the cons associated with switching to a grain-free diet for your dog relate to the many misconceptions people have in regards to whether or not pets should be eating grains, or more loosely, carbohydrates.

As already mentioned, one of the benefits associated with grain-free dog food will mean less chance of an allergic reaction taking place, however, while food allergies do affect dogs, grain and corn intolerance only represents 10% of all allergies diagnosed by vets. This means that adopting a grain-free diet makes perfect sense if your does is allergic, but if your pet isn’t affected, there is no reason to rush to avoid these ingredients.

If you are worrying about an allergy affecting your dog then it is well worth looking into the issue further, itchiness and hair loss can both be common symptoms but as research has shown, beef and dairy cause far more reactions in dogs than grains.

Another benefit for some dogs to avoid grains is how they can also ease digestion issues. However, if your dog doesn’t currently have any negative health issues with their digestion, then their current grain-based diet may not be a problem whatsoever. Transitioning to a new diet when there is no visible need may cause more problems than it can solve.

Studies have even shown that domesticated dogs have had to adapt to how their stomachs digest starch and other food types. This means that although as wolves this is not something they would have done regularly, with the genetic mutations that happened for centuries, domesticated dogs are now able to digest traditional dog food quite comfortably. This is proven by the overall low number of issues related to typical diets dogs have become used to, even though some experts tout the negative effects of such high carbohydrate/low protein intake.

How To Choose a Grain-Free Dog Food

So you’ve now weighed up the pros and cons and come to the conclusion that a grain-free diet is a right approach for your pet? With such an array of choices, it is now time to focus on what to be on the lookout for when buying the best grain-free dog food — this is so you don’t give in to the hype but actually buy the best product out there!

As with more traditional dog foods, you’re given the choice of both wet and dry grain-free dog foods. With both variants, make sure you are paying attention to the below points:

  • the first ingredient must be a quality protein and not another carbohydrate (e.g. potato)
  • wholesome fruits and vegetables providing great micronutrients (vitamins, minerals, and trace elements)
  • use of nutritious pieces of meat while avoiding the use of meat by-products
  • healthy fatty acids to provide enough omega 3 and 6

Other factors to look out for are how grain-free dog food is what additives are in the recipe. Some brands use probiotics, while others use a number of study-proven antioxidants without any additional artificial colors or flavors which can have a beneficial impact on your dog’s health.

Here is a long eight-minute video about the benefits of low-carb dog food:

Ensuring your dog receives a well-balanced and healthy diet should be one of the main priorities of any dog owner. Just as regular walks and frequent grooming mean your dog can live a happy and healthy life, it is important that you know exactly what you’re feeding your pet to make sure their nutritional needs are met. When it comes to feeding your dog, you must focus on both quantity and quality.

Grain-free diets are hype and they mimic the diet of early dogs: more meat, more fat, and fewer grains such as wheat, rice, barley, quinoa, etc. Just like low-fat dog foods, this grain-free diet is a healthy alternative to the regular kibble most dog owners feed their dogs.

Now, because grain-free dog foods are praised and clearly growing in popularity, dog manufacturers are trying (as usual) to use tricks to get you to buy their particular recipe. This is why we’ve listed the best grain-free dog foods in this article so you know what to buy!

    Hello – I have spend the last hour reading your web site, and found it very helpful with what to feed our newest member of our family. She is a 5 month old Golden Lab (but almost white in color, very smart and quick to learn – thank Heavens). What I was concerned about is her coming in heat, we do not want to breed her, but our Vet said that “They – have researched spaying the larger breeds of dogs before they go through one or two heat cycles, and found out that was one of the reasons they have discovered they have physical problems later in life” – – We have been married for 51 years, and have never been without two labs at one time (a dog needs a dog companion, the same as humans) when we lose one, we all mourn her loss, so we get her a puppy and we start another member of our family. But we have always had them spayed between 3-6 months as the Vet always said to.
    We never breed our girls because there are so many puppys and dogs that are available, there are always one that needs a loving home. So now our oldest golden lab, Kayanne, is on pain meds because her joints are bone on bone and she has a hard time getting around. Our next oldest, a black lab, Kandi Kane, is my support dog, she knows when I say work, that I need help to walk without falling when my dead leg gives out, she knows this before I do and won’t let me move without hanging onto her halter, but she is getting old, like me, her hips, so she is on pain meds too. So we now have Kayleigh, who is being trained as a support dog for me, and she is my worry. The Vet said they wouldn’t spay her until two heat cycles, so I found your site to find out the symptoms, so I would know what signs to look out for. Scarey, worrying now for three weeks or more at a time. Is it true that we should wait for two cycles before having her spays? I want to do what is best for her, what is best for her to eat, etc. We have always watched what they eat, their treats, everything is USA made, they go to the Vets regularly, but if we made mistakes with all our other girls, we want our new girl to benefit from more research that is correct for them. All of our girls names start with Ka – – When the time comes, and we know it will, Kayleigh will need a sister companion, so our next girl will be a Black Lab and her name will be Kahlua. Everyone loves our girls because we trained them with lots of love and praise, they know hand signals and verbal commands as well, they have good manners, and they love us as much as we love them -God showed us Mercy when he came us animals to love and be loved by. Thank you for helping so many people with their concerns, and I would like to know about when is right to spay Kayleigh. Have a great day.
    Sincerely – Suzanna
    (I talk a lot, I’m Italian and a people person)

    1. Yes, you should normally leave a couple of heats go by before spaying a female dog.
