But is it actually better, or should you include grains in your pup\u2019s diet? This myth-busting guide aims to help you make an informed decision, backed by expert nutritionist advice.<\/p>\n\n\n\n<p><strong>Key takeaways<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Grain-free food and food that uses grains can both be healthy options \u2013&nbsp;it depends on your dog.&nbsp;<\/li>\n\n\n\n<li>Some dogs have a wheat allergy, or are sensitive to all grains, meaning they might need a diet that avoids these ingredients.&nbsp;<\/li>\n\n\n\n<li>Most dogs thrive on food that includes grains \u2013 they\u2019re packed with nutrients, fibre and energy.&nbsp;<\/li>\n\n\n\n<li>While wolves are carnivores who need meat, dogs have evolved to be able to digest grains and other forms of starch.&nbsp;<\/li>\n\n\n\n<li>Some scientists believe grain free diets may have certain risks for dogs, especially if the ingredients are not nutritionally balanced, leading to deficiencies in important micronutrients.<\/li>\n<\/ul>\n\n\n\n<h6 class=\"wp-block-heading\" id=\"h-table-of-contents\"><strong>Table of contents<\/strong><\/h6>\n\n\n\n<p><a href=\"#h-what-does-grain-free-dog-food-mean\">What does grain-free dog food mean?<\/a><br><a href=\"http:\/\/h-#why-do-some-owners-choose-grain-free-diets\">Why do some owners choose grain-free diets?<\/a><br><a href=\"#h-are-grain-free-diets-better-for-dogs\">Are grain-free diets better for dogs?<\/a><br><a href=\"#h-potential-health-risks-linked-to-grain-free-dog-food\">Potential health risks linked to grain-free dog food<\/a><br><a href=\"#h-when-grain-free-may-be-helpful\">When grain free may be helpful<\/a><br><a href=\"#h-grain-vs-grain-free-which-should-you-choose\">Grain vs grain free: which should you choose?<\/a><br><a href=\"#h-common-myths-about-grain-free-dog-food\">Common myths about grain-free dog food<\/a><br><a href=\"#h-nutritionist-backed-takeaways\">Nutritionist-backed takeaways<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-does-grain-free-dog-food-mean\"><strong>What does grain-free dog food mean?<\/strong><\/h2>\n\n\n\n<p>Grains are edible plant seeds like oats, barley, maize, rice and wheat, so grain-free dog food doesn\u2019t include any of these ingredients. This type of dog food was initially developed for dogs who are sensitive to grains, but over the years it\u2019s found wider popularity.&nbsp;<br><br>Grain-free dog food isn\u2019t the same thing as carbohydrate-free food, as these recipes can use ingredients like potato and legumes instead of grains. At Tails.com, our <a href=\"https:\/\/tails.com\/gb\/diet\/grain-free-dog-food\/\">grain-free kibble blends<\/a> use nourishing sweet potato, potato and beet pulp.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-do-some-owners-choose-grain-free-diets\"><strong>Why do some owners choose grain-free diets?<\/strong><\/h2>\n\n\n\n<p>There are a couple of different reasons why people might choose to feed their dogs this diet.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-suspected-allergies-or-sensitivities\"><strong>Suspected allergies or sensitivities<\/strong><\/h3>\n\n\n\n<p>Some people give their dogs a grain-free diet because their dog is allergic to wheat or other grains, or because they think their dog might be. Symptoms like itchy skin, ear infections or digestive issues can indicate your dog has an allergy or food intolerance. However, symptoms like skin problems are more commonly caused by environmental allergies or flea bite allergies, so make sure you get a diagnosis from your vet before thinking it\u2019s food related.&nbsp;<\/p>\n\n\n\n<p>While some dogs are sensitive or allergic to grains, there are other allergies that are more common. For instance, dogs are more likely to be allergic to certain proteins, like beef, than they are to grains. [<a href=\"https:\/\/www.thekennelclub.org.uk\/health-and-dog-care\/health\/health-and-care\/a-z-of-health-and-care-issues\/food-allergies-in-dogs\/\">1<\/a>] For dogs with extra sensitive stomachs, our <a href=\"https:\/\/tails.com\/gb\/diet\/hypoallergenic-dog-food\/\">hypoallergenic dog food<\/a> avoids the ingredients dogs are most likely to be allergic to: beef, dairy and wheat.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-perception-of-being-healthier-or-more-natural\"><strong>Perception of being \u2018healthier\u2019 or \u2018more natural\u2019<\/strong><\/h3>\n\n\n\n<p>On the other hand, some people go for grain-free dog food because they believe it is healthier or more natural for dogs to avoid this type of ingredient. While dogs\u2019 wild wolf ancestors are carnivores, dogs are omnivores, which means they\u2019ve adapted to be able to digest starches like grains and cereals. In fact, they can get lots of important nutrients and fibre from these ingredients.&nbsp;<\/p>\n\n\n\n<p>Sometimes grain-free diets are advertised as a more premium option, but you don\u2019t have to avoid grains to give your dog a top quality diet that\u2019s full of nutrition. It all depends on your dog\u2019s specific needs and preferences.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-are-grain-free-diets-better-for-dogs\"><strong>Are grain-free diets better for dogs?<\/strong><\/h2>\n\n\n\n<p>Grain-free or gluten-free food might be better in some cases, such as if your dog is allergic to wheat or other grains, but it\u2019s not automatically better in every case.&nbsp;<br>All in all, a balanced diet is what\u2019s healthiest for your dog \u2013 with or without grains. The most important thing is that their diet is what\u2019s called \u2018nutritionally complete\u2019. [<a href=\"https:\/\/www.pdsa.org.uk\/pet-help-and-advice\/looking-after-your-pet\/puppies-dogs\/your-dogs-diet\">2<\/a>] This means that it contains all the vitamins, minerals and other nutrients they need to be healthy, in the right balance for their age, size and activity level. It\u2019s totally possible for your dog to enjoy a healthy, balanced diet whether they eat grains or not.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-potential-health-risks-linked-to-grain-free-dog-food\"><strong>Potential health risks linked to grain-free dog food<\/strong><\/h2>\n\n\n\n<p>While grain-free food can be a perfectly healthy option, there are some risks associated with this type of food, especially when it contains specific ingredients.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-fda-investigation-into-dcm-dilated-cardiomyopathy\"><strong>FDA investigation into DCM (dilated cardiomyopathy)<\/strong><\/h3>\n\n\n\n<p>In 2018, the US Food and Drug Administration began investigating grain-free diets. They looked into whether certain grain-free foods, especially those which had legumes or potatoes as key ingredients, might have any connection to a heart condition called dilated cardiomyopathy (DCM). [<a href=\"https:\/\/www.ukpetfood.org\/resource\/canine-dcm-and-pet-food.html\">3<\/a>] These reported cases weren\u2019t in the UK, and&nbsp;the UK and the US have different legislation and quality standards for pet food. However, there have been more papers published since then which suggest there may be a link between a grain-free diet and heart conditions, although none were published in the UK investigating food made here.&nbsp;<\/p>\n\n\n\n<p>This ongoing research is something to be aware of, although no link has been officially confirmed yet. On this basis, some nutritionists and vets advise that dog breeds who are prone to heart conditions shouldn\u2019t eat a grain-free diet. If your dog belongs to one of these breeds, you can speak to your vet to get personalised recommendations on how to protect their heart health.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-nutritional-imbalance-risks\"><strong>Nutritional imbalance risks<\/strong><\/h3>\n\n\n\n<p>When choosing the best diet for your dog, it\u2019s always important to make sure it\u2019s formulated properly. Some studies have looked into whether legume-based, grain-free diets might be more likely to cause dogs to be deficient in taurine, an important amino acid. [<a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC6396252\/\">4<\/a>]&nbsp;<\/p>\n\n\n\n<p>So swapping grains for other ingredients might change the breakdown of nutrients your dog gets, unless you go for a commercially made grain-free diet that\u2019s designed to be nutritionally balanced. At Tails.com, all our kibble blends are perfectly balanced for every individual dog and their specific needs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-when-grain-free-may-be-helpful\"><strong>When grain free may be helpful<\/strong><\/h2>\n\n\n\n<p>Grain-free diets can be great for some dogs, especially those who have a grain allergy or intolerance.&nbsp;<\/p>\n\n\n\n<p>You might be recommended grain-free or hypoallergenic food for your dog as part of an \u2018exclusion diet\u2019 under vet supervision. This is when you\u2019re trying to find out which ingredients your dog is sensitive or allergic to \u2013 feeding your dog a very limited diet for a few weeks, gradually introducing new foods one at a time. [<a href=\"https:\/\/www.pdsa.org.uk\/pet-help-and-advice\/pet-health-hub\/other-veterinary-advice\/how-to-conduct-a-food-trial-dog\">5<\/a>] If your dog is on an exclusion diet, remember to check the ingredients in their treats, too, otherwise you won\u2019t truly know which ingredients are affecting your pup.<\/p>\n\n\n\n<p>If you\u2019re considering switching to a grain-free diet, speak to your vet first to find out if it would be a good option for your dog. You can also always speak to the friendly nutrition team at Tails.com.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-grain-vs-grain-free-which-should-you-choose\"><strong>Grain vs grain free: which should you choose?<\/strong><\/h2>\n\n\n\n<p>So which should you choose, dog food with or without grains?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-benefits-of-grain-inclusive-diets\"><strong>Benefits of grain-inclusive diets<\/strong><\/h3>\n\n\n\n<p>For most dogs, grains are a brilliant source of lots of important nutrients \u2013&nbsp;especially wholegrains like brown rice and oats, which we use often in our kibble blends. Grains are a good source of vitamins and minerals, with many grains being high in B vitamins, which support energy levels, metabolism and the immune system. They\u2019re also rich in fibre, which aids digestion and helps your dog feel full and satisfied. Lastly, certain types of wholegrains like oats and barley are great sources of slow release energy, so your dog won\u2019t get an energy crash after dinner time.&nbsp;<\/p>\n\n\n\n<p>As well as the health benefits for many dogs, grains are highly digestible. These ingredients are gentle on the stomach, and are easy to break down so dogs can absorb the nutrients they need.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-factors-to-consider\"><strong>Factors to consider<\/strong><\/h3>\n\n\n\n<p>If you\u2019re wondering if you should give your dog grains or not, there are a few things to think about. Your dog\u2019s health is the top priority! What does your vet say about your dog\u2019s diet, and have they recommended any changes, such as avoiding grains? An ideal diet for your dog will be based on a number of factors such as how old they are, how active they are, and their size, as well as whether they have any food intolerances or allergies.&nbsp;<br><br>You should make sure that your dog\u2019s diet is complete and balanced, whether or not it includes grain ingredients. Vets and nutritionists work together to select the <a href=\"https:\/\/tails.com\/gb\/range\/our-ingredients\/\">ingredients<\/a> we use at Tails.com, in both our wet food and our tailored kibble, to make sure that all our food is balanced.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-common-myths-about-grain-free-dog-food\"><strong>Common myths about grain-free dog food<\/strong><\/h2>\n\n\n\n<p>There are a lot of myths floating around when it comes to grain free food for dogs.

Grains are a great ingredient for most dogs\u2019 diets, but if your dog has an intolerance or allergy, there are delicious, healthy alternatives available. However, if you\u2019re looking to switch to a grain-free diet, you should do this under the supervision of a vet or nutritionist, to make sure that your dog\u2019s diet provides them with everything they need.&nbsp;<br><br>Work together with your vet to find the right diet for your dog &#8211; you can also email <a href=\"mailto:hello@tails.com\">hello@tails.com<\/a> to get in touch with our nutrition team for expert advice.

Currently, there is not enough data to say whether it\u2019s the case, but some nutritionists and vets advise that dogs who might be prone to heart conditions shouldn\u2019t eat this diet.&nbsp;<\/p>\n\n\n\n<p><strong>Do dogs need grains in their diet?<\/strong><strong><br><\/strong><\/p>\n\n\n\n<p>Dogs don\u2019t necessarily need grains, but they are a very healthy ingredient, jam-packed with nutrients, fibre and slow release energy. They can be a great addition to most dogs\u2019 diets.&nbsp;<\/p>\n\n\n\n<p><strong>Can dogs be allergic to grains?<\/strong><\/p>\n\n\n\n<p>Yes, dogs can be allergic to grains, although this is not as common as some other allergies. However, wheat specifically is one of the three most common ingredients that dogs can be allergic to, along with beef and dairy.&nbsp;<\/p>\n\n\n\n<p><strong>Should puppies eat grain-free food?<\/strong><\/p>\n\n\n\n<p>Puppies usually haven\u2019t developed allergies yet, meaning that they won\u2019t need a grain-free diet to prevent allergic reactions. Grains are easy to digest for puppies and have lots of nutrients that will help them as they grow. However, they can definitely eat grain-free food, too, as long as it\u2019s nutritionally balanced with everything that growing puppies need.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-sources\">Sources<\/h3>\n\n\n\n<p>[1] <a href=\"https:\/\/www.thekennelclub.org.uk\/health-and-dog-care\/health\/health-and-care\/a-z-of-health-and-care-issues\/food-allergies-in-dogs\/\">&#8216;Food allergies in dogs&#8217;, The Kennel Club<\/a>&nbsp;<br>[2] <a href=\"https:\/\/www.pdsa.org.uk\/pet-help-and-advice\/looking-after-your-pet\/puppies-dogs\/your-dogs-diet\">\u2018Your dog\u2019s diet\u2019, PDSA<\/a><br>[3] <a href=\"https:\/\/www.ukpetfood.org\/resource\/canine-dcm-and-pet-food.html\">\u2018Canine DCM and pet food\u2019, UK Pet Food, 2021<\/a><br>[4] <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC6396252\/\">\u2018The association between pulse ingredients and canine dilated cardiomyopathy: addressing the knowledge gaps before establishing causation\u2019, Journal of Animal Science, 2019<\/a><br>[5] <a href=\"https:\/\/www.pdsa.org.uk\/pet-help-and-advice\/pet-health-hub\/other-veterinary-advice\/how-to-conduct-a-food-trial-dog\">&#8216;How to conduct a food trial&#8217;, PDSA<\/a>&nbsp;<br>[6] <a href=\"https:\/\/www.science.org\/content\/article\/diet-shaped-dog-domestication\">\u2018Diet shaped dog domestication\u2019, Science, 23 January 2013<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Should your dog eat grain free food?
