Best Grain Free Dog Food for Skin Allergies

The 7 Best Grain Free Dog Foods for Skin Allergies

Pooches can be like us, some have more sensitive stomachs and others are prone to skin allergies. Grain-free dog food adopts the ancestral diet to some level, which takes after the diet of wolves.

Wolves didn’t used to eat grains, which is what spawned the idea that grain-free and raw diets are what’s best for our pups. Grains are what research has shown can aggravate the stomach and skin due to certain dispositions the dog may have.

However, if you must include grains in your dog’s diet, whole grains are the way to go. Any sort of whole foods, contribute valuable nutrition such as vitamins, minerals, and much needed fatty acids.

Dog food that lacks grains makes up nutrition in other areas such as added fats, protein, and carbs. Let’s take a look at some of the best grain-free dog food options for skin allergies.

Best Grain-Free Dog Food to Stop Skin Allergies

1. Blue Buffalo Basics Limited Ingredient Diet, Grain-Free

No products found.

Dog food, to be a high-end or just quality food that your dog should absorb should always contain one main ingredient. That is usually the first ingredient listed on the ingredients list.

We always suggest feeding your pup dog food with meat as the first ingredient. The contents are listed in order of percentage that makes up the recipe. The first ingredient is what mainly makes up the meal, and the last ingredient is the one that appears the least. 

This Blue Buffalo grain-free dog food contains deboned lamb as the main source of protein and is the only source in this recipe. This dry dog food is 100% grain-free and gluten-free, reducing the risk of skin allergies and stomach irritation.

As for carbs, instead of grains, they utilize peas and potatoes, so your dog can get his dose of vegetables and the pumpkin and pea fiber help with digestion. When digestion is smooth it eliminates bloat in dogs, which could have fatal effects for some breeds.

What really defines whether a dog food is good for dogs with sensitive skin are the omega fatty acids, Omega 3 and 6 to be exact. This is mostly derived from fish or eggs and even flaxseeds.

Otherwise known as essential fatty acids, they are responsible for your dog’s skin and coat health. Food helps your dog’s appearance as much as other grooming tools listed here.


  • As a limited diet recipe, it greatly reduces the chance for food sensitivities and choosing the ingredients carefully maximizes nutritional value.
  • Deboned lamb as the first ingredient and only source of meat makes this a quality dog food.
  • The carbs chosen in this recipe are easily digestible which helps with sensitive stomachs.
  • Fibers from peas and pumpkins aid in digestion, therefore minimizing bloating. 
  • For skin allergies, the essential fatty acids support skin and coat health.

The grain-free recipe doesn’t contain any by-products, which should never take the place of wholesome ingredients. It’s also important to note whether the dog food contains artificial flavors, colors, preservatives or additives. Naturally, you don’t want any of this in your dog’s food.

What to Look for When Buying a Grain Free Dog Food for Sensitive Skin?

Chances are, dogs with sensitive skin also suffer from other allergies or have sensitive stomachs. There are certain ingredients proven to aggravate allergy symptoms or cause discomfort in a sensitive pup. Y

ou can see more on our article about the best-recommended dog food for anal gland problems. These are ingredients you should avoid. But on the other side of the coin, there are ingredients that help soothe these issues, and you should make sure they rank high on the ingredients list. So what is it that you should be looking for?

Omega Fatty Acids (Essential fats)

Since the focus of this list is on skin allergies, we’re going to start off the list by stating that Omega fatty acids (3 & 6) are vital in the upkeep of your dog’s skin and coat.

Like antioxidants, they also boost the immune system and cell growth. Telltale signs of a dog with an essential fatty acids deficiency are skin irritation such as rashes, dry or flaky skin, and a dull and limp coat. You can change this by adding Omega fatty acid supplements into his or her diet. But we would always suggest taking in nutrition from real food.

Clear Ingredients List

The next parts are important for all dog food. Make sure all the ingredients listed in the ingredients list are clear and identifiable. They should never be suspicious and unclear with the listing, this suggests they are trying to hide some of the sources.

By-products aren’t something we consider to be great for your dog’s diet, but it depends on what the by-product is. Meat by-product could be a good source of glucosamine. Poultry by-products are preferred over meats, but meat meals are almost never good. Dogs that suffer from sensitivity issues shouldn’t ingest any questionable ingredients.

Balanced Nutrition

Perhaps we weren’t clear before, but a balanced meal is one that contains all the necessary nutrients that a dog needs to stay healthy and fit.

This means there needs to be a blend of protein, carbs, healthy fats, and micronutrients (vitamins and minerals). The AAFCO (The Association of American Feed Control Officials) have profiles, which a dog food can pass to obtain a “complete and balanced” badge.

There are other badges a dog food can get, but this is just to prove it is a balanced meal for your pup. There are dog food recipes that exceed these profiles, so you would need to do a bit of research.

It doesn’t require hard digging, because if a dog food has obtained a badge from the AAFCO, they will most likely broadcast that fact.

Wholesome Animal Ingredients

Wholesome ingredients mean less processing and more natural food. From the meat to the vegetables and fruits, whole ingredients will benefit your dog’s overall health.

It leads to healthier digestion as well, as fresh food is more easily absorbed into your dog’s body. With the right foods, your dog will build stronger muscles and a stronger immune system. 


Fruits and vegetables that are packed with micronutrients such as antioxidants, vitamins, and minerals promote a healthier digestive and immune system. Vitamin C is commonly seen and essential for collagen synthesis. As for minerals, you’ll often find calcium, iron, and phosphorus labeled on the back of the box.

No Harmful/Artificial Ingredients

Even if you have the healthiest ingredients, the quality of the dog food can go down the drain if there are harmful additives included. Avoid flavor enhancers, preservatives, and even food coloring.

Anything that is used to make the food looks more delicious is only for your benefit. Your dog will not notice if the kibble or wet dog food is a rich brown color riddled with wet morsels or if it’s puke green.

The more natural the food is the better, and props if you can find organic dog food, which is becoming increasingly more popular nowadays.

If you adhere to these rules, the food may be higher priced, but it’s worth it in the end as it concerns your fur baby’s health. Never should you settle for a cheaper dog food that contains these synthesized materials.

Meat as the 1st Ingredient

As briefly mentioned before, you should look for animal protein as the first ingredient. Ingredients are listed by portion, which means having a clear animal-sourced protein is crucial.

Named animal proteins are words like chicken, lamb, deboned bison, etc. Meat meals and by-products as the first ingredient should be avoided, although they could be acceptable as secondary supporting ingredients.

Dry or Wet Dog Food?

Grain-free dog food can come in the form of wet or dry food. Wet dog food is typically more flavorful and palatable for your fur baby. There is less processing involved and of course, it contains more water.

This is good for fur babies that forget to hydrate. They are less filling and don’t last as long as dried kibble though. It can also be messy and get all over the place.

As for dry dog food, it’s much more popular among dog parents due to the cheaper price and longer shelf life. It’s easy to store and travels well.

Some kibble can even help with dental care by reducing plaque and tartar buildup. However, for older and young pups, kibble could be too hard to digest/chew. Therefore, you may need to soak it in water.

There are Good Grains

There are such things as good grains such as quinoa. If your dog doesn’t seem to have sensitivities to grains, they can do a world of good. If grains are in your dog’s diet, make sure they are wholesome grains.

More examples of “good” grains are brown rice and oats. Grains can be your dog’s main source of amino acids. 

Final Thoughts

Dog food is a very inconsistent topic. There are always new studies coming in debating what new diet trend is the best for your pet. We often see this with human diets as well such as the Keto diet. Each pet’s needs are also different.

It’s important to understand your dog, his needs and his preferences before you throw money away. A lot of the brands do come with a satisfaction guarantee and allow you to switch out the food for a new flavor/recipe if your dog doesn’t take to it.

The more expensive price tag on higher quality dog food is there for a reason because better ingredients are used. Don’t skimp on food as it could be detrimental to your dog’s health.
