What Is the Best Grain Free Dog Food for Skin Allergies?

By: Serena Law | Updated: September 11, 2019

Allergies and intolerances in dogs can be a serious issue. An allergen is a usually harmless substance with the capability of triggering a response in the immune system. However, when the immune system perceives one as a threat, this leads to an allergic reaction. The allergen can be a substance a dog has eaten, inhaled or has come in direct contact with the skin. Regardless of the cause of the allergic reaction, most symptoms are evident in the skin.

While some allergens such as dust may not be easily avoidable, food certainly is. Grain allergies, for instance, are very common in dogs and usually manifest in the skin. The good news is that grain allergies are easily prevented with grain free dog food. Dogs that will benefit from eating grain free food still need to have a complete and balanced diet with all the necessary nutrients. Not all formulas can provide this, which is why we have completed the extensive research to accelerate your pooch’s road to recovery.

This article features the 5 best grain free dog food for skin allergies. We also describe some of the common symptoms of food allergies, what types of dog food can help prevent allergic reactions and what to look for in grain free dog foods.


What are the most common food allergens?

Just like humans, dogs can develop allergies to a variety of substances. The most common food allergens for dogs include chicken, beef, dairy and egg. Dogs can also become allergic to grains. As you may notice, these are also products commonly found in many commercial dog foods.

What are the symptoms of a food allergy?

The most common symptoms of a food allergy include skin rash, hives, hair loss, itching, paw biting or excessive licking. Dogs can also experience nausea or vomiting.

What other types of allergies could my dog be suffering from?

Food allergies can share the same symptoms of other health conditions or allergies. For example, itchy skin can be a sign of flea allergy. In fact, the most common canine allergy is fleas, followed by environmental allergies such as dust mites. If you notice that your dog’s symptoms come and go as the climate changes, it is likely to be a seasonal allergy. It is important to be attentive to any symptoms as they arise, as seasonal allergies can worsen and continue throughout the year.

If you have ruled out environmental or seasonal allergies, then your dog’s diet is a likely source of the symptoms.

Is My Dog Suffering from Food Allergies Or Food Intolerances?

Food allergies vs food tolerances Best Grain Free Dog Food for Skin Allergies


Food allergies and food intolerances are two different concerns.

Food allergies take place when a dog’s immune system mistakenly labels a particular ingredient as harmful. As a response, the immune system creates defensive antibodies to fight the invaders (the ingredient) leading to an immune reaction such as skin rash and itching.

On the other hand, food intolerances are a digestive-related issue the digestive system is unable to digest a specific ingredient. Lactose intolerance is a common condition for dogs. It is experienced when a dog is unable to break down lactose, a sugar found in milk. You may notice digestive related symptoms such as gas, bloating, diarrhea, nausea or vomiting.

A dog’s symptoms can easily differentiate whether they are suffering from food allergy or food intolerance.

Types Of Dog Food Best for Skin Allergies

To cope with food allergies, most owners opt for a grain free diet for their pooch. As well as being grain free, dog foods should contain limited ingredients or be hypoallergenic.

Grain Free

Grains are small seeds that originate from specific grasses that are a high source of carbohydrates. A grain free diet consists of dog foods made without wheat, corn, soy, rice, oats and similar ingredients that are usually related to food allergies. As a bonus, the carbohydrates used in grain free foods are often healthier options such as sweet potato. This is a great option if you are looking to lower your pup’s weight and carbohydrate intake, as well as managing their food allergies.

Limited ingredients

Typically, these foods consist of a single primary protein source, such as salmon or duck (rather than the usual chicken or beef which are both common allergens) and one carbohydrate source. With fewer ingredients, it reduces the exposure to potential allergens and decreases the likelihood of a break out. Look for formulas that exclude unnecessary additives. Limited-ingredient dog foods can also be used for elimination, making it easier for identifying the specific ingredients that a dog is allergic to.

All our featured products use a grain free and limited ingredients recipe.

Hypoallergenic Foods

Additionally, hypoallergenic dog foods are great to look out for. These foods are often created using proteins that have been broken down into their basic building blocks. This process can make the allergen somewhat undetectable in a dog’s immune system. This then reduces the likelihood of your dog experiencing an allergic reaction to the food.

Benefits of Grain Free Dog Foods

Benefits of the Best Grain Free Dog Food for Skin Allergies


Whether or not your dog experiences allergies or stomach issues, they can benefit from a grain free diet. Some examples include:

  • Easier digestion. Dogs find it difficult to digest refined grains. A diet that is free from grains is less likely to cause stomach problems because it is easier to digest.
  • Nutrition. Many manufacturers use a carbohydrate as the main ingredient in their formula. This is not found in grain free food.
  • Weight management. Grain free formulas consist of healthier carbohydrate sources such as from vegetables. As long as a dog is fed moderately, this type of food will aid weight management and prevent obesity.
  • Allergies. Wheat and soy are one of the most common grain allergens, so excluding grains in a diet will prevent allergic reactions.

What to Look for in Grain Free Dog Foods

In order to look for the best grain free dog food for skin allergies with nutritional value, we recommend looking for the following qualities:

  • Protein as the main ingredient. Formulas that will fulfil a dog’s dietary requirements should have a meat-based protein as the first ingredient.
  • Sources of carbohydrates. Some manufacturers will substitute grains with unhealthy carbohydrates. Try to avoid these and look for formulas with healthy vegetables such as sweet potatoes, carrots and peas.
  • All natural ingredients. A healthy, complete and balanced diet should be free from artificial flavors, colors and preservatives. Like with all dog foods, try to look for products made from high-quality fresh and natural ingredients.

How to Switch to a Grain Free Diet

All food transitions should always take place in a gradual manner.

petMD suggests starting with 20% of the new food with 80% of the old. Increase the new food by 20% while decreasing the old food by 20% per day (e.g. day 2 involves a mix of 40% new food and 60% old food), until eventually your dog is consuming 100% of the new food. The whole process should take around 5-7 days.
