US Vet: “This is the Best Limited Ingredient Dog Food in 2022”

A limited Ingredient food can benefit your allergic dog. However, it’s crucial to ensure that your dog will get all the necessary nutrients from fewer ingredients.

I used my 12 years of Veterinary experience to review over 30 dog food products to find the best limited ingredient dog food.

After evaluating over 30 dog food recipes, I found that “Wellness Simple Limited Ingredient Diet Grain-Free Salmon & Potato Formula Dry Dog Food” has the best overall combination of nutrients, and quality sources. 

But I understand that no two pups are alike, and your doggie might have a different life stage or have different needs, such as a sensitive stomach or skin allergies. That’s why I prepared a shortlist of the best limited ingredient dog foods that address these common conditions.

Before you pick the best limited ingredients dog food for Fido, it’s always important to consider whether it’s the right thing to do. That’s why I explained how to know if your dog needs to get on a LID diet.

After you decide that Limited Ingredient Dog Food is right for your doggie, you can check out these 10 limited ingredient dog foods that I shortlisted for you

If my shortlist doesn’t cover your doggie’s needs for some reason, I prepared a quick checklist that would assist you in finding the best limited ingredient dog food for her. I wrote the checklist in plain & simple English so that you can follow it easily.

Finally, I answered popular questions patients have asked me regarding limited ingredient diets.

Always remember that the recommendations in this review are not intended to replace a doctor-patient relationship. Always consult your veterinarian before making significant adjustments to your furbaby’s diet.

Let’s get started.

Is a Limited Ingredient diet safe for your dog?

A Limited Ingredient dog food is a dog food with significantly less ingredients than the average dog food. It is extremely useful in diagnosing sensitivities to certain ingredients.

If your dog doesn’t display signs of allergies or stomach sensitivity, it would be good to pick a different diet.

Feeding a LID does not mean that you’re offering your pooch limited nutrition. If the product contains the right blend of protein, carbs, healthy fats, and essential vitamins and minerals, you’re offering complete nutrition.

When your pup has food sensitivities requiring a tailored diet, limited ingredient dog food may be wise. These products, also known as limited antigen dog foods, rely on a minimal number of materials in the formula. This usually includes a single animal protein source and a single carbohydrate source.

Diagnosing Food Allergies by Feeding a Limited Ingredient Diet

If you suspect that your pup has a food allergy but don’t know which material is the trigger, consult with your veterinarian about using a limited ingredient diet (LID) also known as an elimination diet to identify the problem food or foods.

With an elimination diet, you transition off your dog’s current diet to a balanced recipe with a single protein and a single carbohydrate. These ingredients should be novel to your pooch so that his digestive system hasn’t built any resistance to them. Any treats you offer should have the same ingredients as those in the LID. Feed the elimination recipe until your furbaby has no allergy symptoms (eight to twelve weeks). Then you can gradually reintroduce the suspected allergens, one at a time. If no symptoms appear in two weeks, that food is likely not the culprit. Any time you see a reaction, remove the offending ingredient. 

How Many Ingredients Are There in a Limited Ingredient Dog Food?

There are currently no regulatory guidelines for the number of ingredients in limited ingredient dog food. These products tend to have fewer materials than the average dog food, but the number varies between manufacturers and recipes. Commercial limited ingredient foods usually have between four and nine ingredients and may use novel protein and carbohydrate sources.

A strictly limited ingredient recipe such as one may use in an elimination diet usually has the following features:

  • No fillers – beet pulp, corn, wheat
  • No animal by-products
  • Often grain-free
  • Usually only has one animal protein and one carbohydrate
  • No supplements

Provide all the Nutrients with Less Ingredients

When picking the right dog food formulation, you need to ensure that your dog will receive all the required nutrients. With limited ingredient diets, it’s highly important. Since we’re going to eliminate the majority of the ingredients, we need to make sure that we won’t eliminate the important nutrients.

Not very long ago, there were only a few limited ingredient dog food options available. But now, you can choose from gluten or grain-free options, various protein sources, and many different brands. 

For your convenience, we’ve created a rule of thumb checklist to make it easier for you to choose the right LID formulation that fits best for your doggie:

  • Protein – If your pup has a food sensitivity, you should look for a diet with a single novel protein such as duck, wild game, or venison. For some dogs, protein from lamb and fish may also qualify if they’ve never had food with these ingredients. The most common food allergens for canines include the proteins beef, chicken, and pork.
  • Carbohydrates – Some pups are sensitive to grains or the gluten that’s in common cereal grains. When choosing a LID, look for a shortlist of novel carbohydrates, including garden vegetables and ancient grains.
  • Grain-Free – Most but not all LID foods are grain-free. At a minimum, look for products that are free of corn, wheat, and soy. Some ancient whole grains like millet and quinoa may be a good fit, depending on your pooch. 
  • No Supplements – Limited ingredient diets focus on easily digestible foods that are gentle on the gut. The label should have a simple list that includes no additives or supplements that could be upsetting. 
  • Less Rigorous LIDs – Some less strict versions of an elimination diet may offer one protein and two carb sources or a protein, a fat, and a carb source in their food. They will usually have a range of between four and nine total ingredients. 

In the case of commercial products, some foods may have two novel proteins or two novel carbs. They may also use different variations of a single protein source such as venison, venison meal, and venison liver. Prebiotics and probiotics are also acceptable in commercial LID products.

Once we’ve decided which ingredients we’d like to have, we need to ensure that the dog food would match the highest standards.

  • Look for Products Manufactured in a Country With Rigorous Safety Protocols – One way to minimize the risk of feeding a product that contains unidentified ingredients is to choose food that’s produced in a nation that follows strict protocols for sanitation and manufacturing. Countries such as the United States, Canada, Great Britain, and Australia follow good manufacturing practices to help ensure safe and wholesome food production.
  • Avoid Dog Foods With Artificial Additives – It’s not just animal proteins and grains that can cause food sensitivities or allergies. Artificial ingredients such as colors, flavors, or preservatives can be irritating to the gut. And some have been linked to other health issues like cancer. Choose products with natural ingredients and preservatives such as herbs or tocopherols like vitamin C.
  • Choose Foods That List Specific Ingredients – It’s best to avoid products that use general descriptions like “poultry” particularly if your pooch has an allergy to a specific poultry species such as turkey or chicken. Look for species-specific terms like duck, pheasant, or turkey. Another term to watch out for is “blend.” Many times blends of vitamins or other ingredients can include botanicals, condiments, plants, or other materials that may trigger an allergic reaction or sensitivity.
  • Choose Food Appropriate for Your Dog’s Life Stage – When choosing LID food for your furbaby, it’s important to select a product that’s formulated for his life stage. Puppies have different nutritional needs than adults or seniors because their bodies are still growing. If you have a senior that’s less active, choose a senior formula to provide the appropriate levels of protein and energy for his needs.

Frequently Asked Questions

dog smiling after finishing his limited ingredients based meal

What food is best for dogs with itchy skin?

LID dog foods are an excellent choice for animals suffering from itchy skin. These products can help you to pinpoint and avoid trigger ingredients. To further support skin health, you should look for products that have sources of omega-3 and 6 fatty acids. Because grains and starches like potatoes and legumes break down into sugars that can lead to yeast infections, you should avoid these ingredients.

What is the most common food allergy in dogs?

The most common food allergens for dogs are from proteins, particularly animal-based proteins.

What protein are dogs most allergic to? 

Proteins from dairy, beef, chicken, chicken eggs, lamb, gluten from wheat, or soy are the most common allergens for dogs.

Is Limited Ingredient Dog Food Good For Dogs?

Limited Ingredient Dog Foods aren’t necessary if you have a healthy dog, but they can be very helpful if your pooch has food allergies or sensitivities.

How can I help my dog with allergies?

If your dog has allergy symptoms like pawing at the ears, constant licking and itching, skin rashes, recurring ear infections, or loose stools, consult with your veterinarian. You may want to conduct a food elimination trial to identify food allergens. Then, choose an appropriate LID to reduce the risk of reactions.

What’s the Difference Between a Food Allergy and a Food intolerance?

A true food allergy involves an immune response of the body to specific food or foods. For this to occur, your dog would have to eat the material to develop a hypersensitivity. If he consumes the food again, there will be an adverse reaction. Food allergies are rare. Food intolerances, on the other hand, will yield an adverse reaction that is not immunologic.

Can a dog be allergic to all protein?

Any pooch can develop an allergy to any protein source if the body identifies the substance as a threat or invader. However, dogs usually have a limited scope of allergies, and food allergies are not that common.

What do you feed a dog with a protein allergy?

If you can identify a particular protein as the source of your furbaby’s allergies, you can select limited ingredient diets that do not contain those foods.

Can too much protein cause itchy skin in dogs?

It’s more about the type of protein than the amount of protein. If your pooch has a sensitivity to certain proteins, you should eliminate them from his diet.

What is the easiest protein for dogs to digest?

The most digestible protein for dogs is eggs followed by fish meal, lamb, chicken, then beef.

What’s the Difference Between LID Food and Grain-free Food?

Although both foods are formulated to help pups with sensitivities, there are significant differences between LID and grain-free foods. 

Grain-free Foods

The main difference is that grain-free foods contain absolutely no grains, including:

  • Cereal grains such as wheat and corn
  • Whole grains including rice and oats
  • Ancient grains like amaranth and quinoa.

When you look at the label of a grain-free food, you also may notice a long list of ingredients. These products can include other substances like vegetables and fruits to provide essential nutrients. They also may have multiple protein sources.

LID Foods

LID foods may contain one or two grains as their carbohydrate sources. However, the grains are probably not the traditional wheat or corn but rather an ancient grain such as millet. These products have a short ingredient list of about four to nine items. Under the definition of a LID that we shared above, they will only have one or at most two proteins and one or two carbs.

Final Woof

dogs thanks his owner for choosing him the right food

When dogs develop sensitivities or allergies to food materials, you need to find products that don’t contain the offending foods. Whether you’re trying to determine which allergens affect your furbaby or avoiding the ones you already know to be a problem, LID foods can help.

The top commercial products will feature a short list of ingredients (around four to eight) and a single animal protein source. They should be free of substances that could trigger a reaction, including artificial ingredients and fillers. 

For the best results, limited ingredients should provide natural omega fatty acids and other essential nutrients. 

After evaluating over 30 products on the market and comparing them to our criteria and key considerations for the best Limited Ingredient dog food, we recommend Wellness Simple Limited Ingredient Diet Grain-Free Salmon & Potato Formula Dry Dog Food.

This product has a single protein source, five digestible key ingredients, and essential nutrients for total health. But, of course, you should always follow your veterinarian’s recommendations for your furbaby.
