Hypoallergenic dog diet is a must for every pet that may have food allergies. These kinds of foods help minimize the triggering of an allergic reaction in highly susceptible breeds and help prevent the development of itchy and dry skin, vomiting, diarrhea, and excessive gassiness as well as skin and ear infections. Choosing the best nutrition type and products is thus, important if we want to ensure optimum gastrointestinal, immunologic, and overall health for our furry friends.

Unfortunately, not all products can provide such guarantees. There are certain brands that contain substances that can somehow trigger an allergic reaction. This can be particularly frustrating especially for the new pet owner who has very limited knowledge about canine allergies, much less its management. While there are plenty of products on the market to choose from, one of the major issues that every pet owner has to confront is choosing which product is the right one for their respective dogs. Each dog is inherently unique and may respond to a particular product differently. This can complicate the selection process as owners will have to jump from one brand to the next until they’ve found the “ideal” food for Fido.

It is for this reason that we’re sharing with you the results of our extensive research in the hope of making it a lot easier for you to make the correct decision when it comes to choosing the right and most appropriate type of diet or product for your pet. We spent considerable time reading through the hundreds of consumer reviews as well as technical papers written about these products, analyzing each entry to help guarantee that you’re getting only the best ones your puppy deserves.

All of the formulations are also ensured not to contain meat by-products as well as highly allergenic ingredients such as wheat or wheat-gluten.

One of the major drawbacks of Holistic Select, as observed by some dog owners, is that it doesn’t allow for the efficient identification of a possible allergen, especially if you purchase non-single-protein source variants like salmon and anchovy and anchovy, sardine, and salmon. This has led to some cases of worsening of allergic symptoms in dogs. Nevertheless, you still have single-protein choices in turkey, lamb, duck, and chicken.

2. Wellness Simple Natural Limited Ingredient Dry Food

Wellness Simple Natural Limited Ingredient came up as one of our top picks and the highest rated hypoallergenic dog food that you can give to your beloved pet. Each formulation of this product consists only of two ingredients – a protein source and a carbohydrate source, either potato or oatmeal.

Being a single-protein source, Wellness gives you the ability to determine which among the different kinds of protein sources your beloved pet is particularly reactive to. This essentially gives you the power to identify which proteins are healthy for your dog and which ones are not.

Nevertheless, being able to identify that your pet is allergic to these protein sources is already a significant step towards the determination of a more gut-friendly diet for your dog.

Another important issue raised by concerned pet owners is the significant difference in the quality of the Wellness Simple.

Also added are Vitamin C and Vitamin E for optimum cellular and immune system functioning, respectively.

What many dog owners noted is that their pets have become less prone to diarrhea and itching and showed signs of continuously improving overall health. The moisture content of Instinct is also noteworthy, allowing for greater skin health.

Unfortunately, the new formulation of Instinct Limited has substantially less animal protein component than its previous versions leading to some dog owners to comment that it is a very bad move for the company, destroying a credible product just to cut down on manufacturing costs. Sadly, too, the new formulation has produced some allergic reactions in a few dogs. Nevertheless, it should still be a very formidable diet to give to your canine friends what with the long history of Instinct’s high animal protein content.

  • Fortified with essential fatty acids, vitamins, and minerals


  • Substantially less animal protein than it used to have
  • May cause allergies in dogs that are sensitive to plant-based proteins

4. Royal Canin HP Hypoallergenic Hydrolyzed Protein

First and foremost, the Royal Canin HP Hydrolyzed Protein is a prescription canine diet that’s specifically designed for dogs with food allergies.

Its formulation requires the breakdown of major plant-based proteins – mostly soy – into smaller substances known as amino acids.

However, on the brighter side, once your dog has completely recuperated from its illness and its digestive system has fully recovered, you can always slowly make the transition to other diets that are less expensive than the Royal Canin HP.

  • Soy-based amino acids as main components


  • Very pricey

How to Choose the Right Diet for Pet’s with Allergies?

Choosing the right food for your pet dog requires a careful understanding of how food allergies occur in the first place. Since dog allergies have the same physiology as in human allergies, it is important to take note that any food item that may have a particular protein molecule to which your dog’s immune system cells are particularly reactive to has the potential to cause an allergic reaction. As such, here are some things you need to consider.

* Always check with your veterinarian about the most appropriate type of diet.

* Choose a product that contains a single protein source and one that is highly uncommon, known as novel proteins, such as turkey, duck, bison, rabbit, venison, and fish. Lamb used to be a novel protein. However, because it is now increasingly used in a lot of commercially available dog foods, it has somehow lost its hypoallergenicity.  

* Choose one that contains hydrolyzed proteins as these avoids immunogenic detection by immune system cells, thus, not triggering any allergic reactions.

* Choose kibbles that contain starches since these are known to be less allergenic than other types of carbohydrates. Excellent examples are rice, potatoes, sweet potatoes, and sweet peas.

* Choose kibbles that do not contain animal- and plant- proteins that are known to be allergenic including chicken, beef, and now, even lamb.

* Choose products that does not contain any of the ingredients that are commonly found in ordinary products including fillers, preservatives, and artificial colorings and flavorings.

* Pick the products that are free from grains such as soy, corn, wheat, and yeast.

The Main Benefits of Hypoallergenic Products

Aside from the fact that you will be effectively ensuring their optimum health, you will also be able to provide a much safer environment for them just by knowing what to avoid. Here are some of the benefits:

* Helps identify allergenic triggers in your dog’s diet – When used as part of a hypoallergenic trial you can use these types of kibbles to identify the different allergenic triggers in your pet’s diet. While it usually takes a few months before you can expect the results, at any rate, you will be glad to learn which type of food your pooch is allergic to.

* Improves digestive health – Giving your pet hypoallergenic kibbles essentially rests its digestive system. This is especially true if you give hydrolyzed proteins as the digestive tract no longer has to work as hard to digest and process large protein molecules. This allows your digestive tract to rest and recuperate, leading to optimum digestive health. This translates to better nutrient absorption and healthier elimination of wastes.

* Enhances immune responses – By slowly removing the allergenic substance from your dog’s system, the immune system is thus, primed for optimum functioning since it doesn’t have to constantly mount an allergic response every time a potential allergen is detected.

* Supplies the canine body with needed vitamins and minerals – Many of these products come fortified with essential fatty acids, minerals, vitamins, and other nutrients that are essential in the promotion and maintenance of optimum canine health.

  • What is a hypoallergenic type of diet?

This kind of diet consists of products that have a decreased tendency to stimulate or provoke an immune response that leads to an allergic reaction.

  • Why does my pet need it?

Like allergies in humans, allergic reactions can produce a variety of problems that can ultimately affect the overall health and wellness of the dog. By providing a special diet, the symptoms are minimized, the digestive tract is rested and allowed to recuperate, and the immune system is tamed for more appropriate immunologic responses.

  • What are the symptoms of food allergy in dogs?

The symptoms can include, but not limited to, itching, chronic ear inflammation, poor quality of coat, skin rashes, paw biting, obsessive licking, chronic diarrhea, vomiting, nausea, hives, chronic gas, and even itchy rear end.

  • Why is my dog allergic to some types of food?

Allergic responses are triggered by the recognition of the body’s immune system cells of the presence of a substance that is considered to have a certain protein marker that is deemed as “harmful” by the immune system cells. Any protein source that carries this “marker” can eventually trigger an allergic response. It is also because of this that some ingredients are known to be more allergenic than others because of the way their proteins are structured.

  • How is allergy diagnosed in my dog?

It can be diagnosed in one of two ways. The first is the introduction of a novel protein source to help reduce the incidence of an allergic response. The second is the introduction of hydrolyzed proteins which effectively bypasses the recognition of these molecules by the immune system as allergenic. In either method, the dog should be fed these hypoallergenic dietary products for a minimum of 8 weeks to assess the pet’s immunologic response. Confirmation is needed by feeding your puppy with the regular diet again for about 2 weeks upon which the usual allergic reactions should be observed. In such cases, you can say your dog has a fair case of food allergy.

  • What are the best food options for your dog with allergies?

Novel proteins and hydrolyzed proteins are two of the currently recognized types of diets that are specially designed for this. However, it should be understood that those brands that are prescribed by veterinarians are often better and more effective, albeit more expensive than those that can be bought off the shelf.

Meeting your pet’s dietary needs helps ensure optimum health by facilitating the recuperation and return to optimum health of its digestive system. It is also beneficial in the sense that the canine immune system will be better equipped to respond to other immunologic insults to further improve the overall health of your dog. These types of kibbles also help in the promotion and maintenance of optimum canine health through the inclusion of other helpful nutrients in their formulation. Best of all, these types of food allow you to identify the best and most appropriate nutrition for your best friend.

In choosing the best one though, it is important to always seek the advice of a veterinary professional since he is in the best position to determine whether your dog really has an allergy or some other health condition that mimics the signs and symptoms. As a general rule, choose products that do not contain anything commonly found in ordinary kibbles, are free from grains and gluten, and are composed of only a single-protein source, preferably one that is considered as novel protein.
