Best Hypoallergenic Dog Food for Dogs with Allergies

When you are seeking a good food to eliminate your dogs allergies, you are really looking for a food that does not include the most common allergens (chicken, beef, wheat, eggs, and corn). But you should also avoid foods that contain unnecessary additives and byproducts, which may contain allergens too.

Many such foods are labeled as hypoallergenic, but this just means that they contain fewer allergens than normal food (the prefix hypo means less or fewer).

Obviously, there is a great deal of wiggle room in this definition, so it is important to consider all the ingredients contained in a given dog food, and not just the marketing claims.

Additionally, some good foods for dogs battling allergies feature hydrolyzed proteins, which should (theoretically) prevent allergic reactions from happening at all.

The following products are all generally good choices for dogs with food allergies, although, of course, the best food really depends on your dogs unique issues.

Why Dog Food Allergies Are So Difficult to Deal With

Food allergies are a tough issue to crack in canines.

Treating your dogs environmental allergies typically involves reducing your pets exposure to the offending allergen, and then starting them on a therapy to gradually desensitize their body to the substance.

Although theres no guarantee of success, these strategies can help alleviate the symptoms of many canine allergy sufferers.

But food allergies present an especially challenging problem. After all, you cant very well reduce your pets exposure to food at least not for more than 12 to 24 hours at a time.

Accordingly, food allergies must be treated by altering your pets diet in very specific ways to help eliminate the allergens, without neglecting your dogs nutritional needs.

Symptoms of a Food Allergy in Dogs

Dogs suffering from food allergies often exhibit a collection of relatively consistent symptoms. However, because these symptoms can mimic the symptoms of other illnesses, its wise to bring your dog to the vet for an evaluation if you suspect a food allergy is involved.

Fortunately, while food allergies are troubling and frustrating problems to deal with, they are rarely life-threatening as they are for humans so thats a plus!

Whereas humans often suffer from a swollen throat or difficulty in breathing after consuming an allergen, dogs most frequently suffer skin ailments as the result of allergic reactions.

Dogs express allergies a bit differently than us. It may seem natural to humans that an environmental/inhalant allergy results in sneezing, while a food allergy results in vomiting or a swollen throat.

However, most dogs exhibit nearly all their symptoms through itchy, irritated skin, and possibly chronic ear infections.

Some of the most common symptoms of food allergies in dogs include:

Other, less common symptoms that may also signify a food allergy include:

• Poor growth in young dogs
• Wheezing
• Coughing
• Sneezing
• Excessive gas
• Vomiting
• Diarrhea

Temporal factors can also provide clues to your dogs condition. Because dogs are typically exposed to food-born allergens on a consistent basis, their symptoms dont wax and wane as they would with exposure to an environmental allergen, such as pollen, dust or dander (which are more common during certain seasons).

Dog Breeds That Frequently Display Food Allergies

Food allergies can afflict dogs of any breed or combination thereof. However, they appear to be more common among some breeds than others.

Some of the breeds that commonly suffer from food allergies include:

• Lhasa apso
• West Highland white terrier
• Dachshund
• Cocker spaniel
• Boxer
• American pit bull terrier
• Dalmatian
• German shepherd
• Labrador retriever
• Golden retriever
• Miniature schnauzer

If you own one of these breeds, be especially alert for signs of a food allergy.

Common Dietary Allergens for Dogs

Allergies are caused by proteins that over-stimulate the immune system.

The most common meat allergies for dogs are:

Beef, chicken, lamb, fish, and pork are all dog food meat ingredients that have been known to cause allergic reactions in dogs.

Youll notice that theyre some of the most popular ingredients in dog food, and since exposure to these ingredients is common, theyve become common allergens.

Other common dog food allergens that are not meat-based include:

• Dairy
• Corn
• Wheat
• Soy
• Yeast

As you can see from this list, allergens arent only caused by foods humans think of as protein sources. In reality, most foods even vegetables and grains contain some proteins. Accordingly, the proteins in things like wheat, soy and corn can also elicit allergic reactions.

Unfortunately, these are all common ingredients in commercial foods, and unless you actively work to avoid these ingredients, your pooch will likely be chomping them up in her kibble.

When your dog has a food allergy,your dogs digestive system fails to digest some of the proteins in the allergy-inducing food. When these whole proteins contact specialized receptors in the intestines, the body treats them as dangerous invaders.

This causes the immune system to launch a disproportionate response, which causes the side effects associated with a food allergy.

Some grains, such as cereal grains, also have the potential to cause allergic reactions in dogs. Interestingly, this isnt necessarily due to the grains themselves in some cases, its a result of the bugs that get into these grains.

Yes, bugs get into grain supplies on occasion. Sorry to share such gross news, but it is the truth.

Accordingly, grain-eating bug carcasses and their droppings can be found in some dog foods. And since grain mites are close relatives of dust mites (which are common allergic triggers for humans),its no shock that the grain mites that wind up in your poochs food and possibly be the culprit of allergic reactions.

Whether its the actual grains or the bugs within the grains that are at fault, grains occasionally cause dogs to have allergic reactions. It should be noted though that there are plenty of great healthy grains for dogs that dont usually cause any issues the majority of dogs digest grains without issue.

Distinguishing Between Food Allergies vs. Simple Food Intolerance

In addition to recognizing the possible signs of a dog food allergy, its also important to distinguish between true food allergies versus a simple intolerance.

When your dog has an allergy, it means that your dogs immune system is overreacting to a normally harmless substance (called an allergen). Intolerance simply suggests your dog has trouble digesting something, in which case switching to a dog food for dogs with sensitive stomach may provide a quick fix.

You should always consult your veterinarian before self-diagnosing your dogs food allergies or intolerances. However, in general, dogs that have true food allergies will generally exhibit skin problems, while dogs with a food intolerance will just display intestinal upset. This commonly takes the form of gas, bloating, vomiting, or diarrhea.

Some food allergies may also cause digestive upset, but skin conditions are almost always the most prevalent problem.

Its very common for dogs to be intolerant of things like dairy products (in fact most adult mammals lack the necessary biochemistry to properly digest the whey protein found in dairy humans capable of doing so are the exception!) and fatty foods.

While dairy and high-fat foods often cause digestive issuesin canines, many pooches can eat one but not the other. For example, my Rottweiler is capable of digesting fast-food quantities of fat (just like her daddy), but a teaspoon of ice cream can make her hurl.

In an ideal world, you should probably avoid giving either type of food to your dog, regardless of the different biological factors at play.

Your dog may appear to take stomach ailments in stride, but you can bet they arent fun and they often lead to further problems.

What Causes a Dog to Develop a Food Allergy?

Unfortunately, while researchers understand that food allergies are the result of an immune system overreaction, they do not understand what makes some dogs more vulnerable to the food allergy phenomenon.

Some believe that food allergies are the result of a genetic anomaly (as they are thought to be in humans) something your pup is simply born with.

Others believe that food allergies are environmental that they happen as a result of what your dog is fed and exposed to.

The fact that some breeds and bloodlines appear to be more prone to food allergies than others supports the genetic argument, but the fact that dogs from similar regions often exhibit similar allergies supports the environmental hypothesis.

Despite the many questions surrounding food allergies, researchers are pretty sure of one thing: Allergies occur in response to exposure to a given allergen, and they often take some time to develop.

Dogs do not often show signs of an allergy to a food the first time they consume it; symptoms appear after repeated exposure.

Some veterinarians recommend limiting the number of proteins you offer your dog over the course of her life. This will hopefully limit the number of allergies that develop, and it can make treatment much easier if a food allergy ever occurs.

For example,a dog fed lamb, beef and chicken throughout her life will have been exposed to these various foods, which could cause them all to spark an immune response. This woulddrastically limit your options for a safe food source.

While a dog fed a vast array of protein sources may be at risk for several different allergens,by contrast, a dog raised solely on chicken can continue to be offered a variety of different protein sources to which she has never been exposed.

Are Antibiotics At Play?

Some veterinarians suspect that antibiotics administered early in a pups life may also lead to allergies.

As a potential solution, they recommend providing young dogs with a probiotic supplement to help bolster healthy gut flora.

However, this proposed treatment hasnt yet been investigated thoroughly in dogs, and human-based research into this area has yielded mixed results, so theres no guarantee of a solution quite yet.

In all likelihood, the answer will eventually turn out to be a combination of factors, but only time (and more research) will reveal the answer.

When Do Dogs Develop Allergies?

No matter the case, dog food allergies can manifest at any point in your pups life.

You may, for example, feed your dog chicken-based food for most of her life, only to discover that at some point, she begins exhibiting signs of an allergy to the food. And because the proteins contained in chicken are very similar to those in turkey, she may become allergic to all varieties of poultry.

How Likely Is It That My Dog Has a Food Allergy?

While allergies among dogs arent unusual, food allergies are somewhat uncommon.

According to Doctors Foster & Smith, food allergies account for just 10% of all allergies seen in dogs. Theyre the #3 most common form of dog allergies, behind flea bite allergies and atopy. Make sure to investigate these possibilities before moving forward with your food allergy hypothesis.

The truth is that your dog is much more likely to suffer from a different kind of allergy rather than a food allergy.

Treating Dog Food Allergies: What Is an Elimination-Challenge Diet?

When it comes to figuring out exactly what ingredients are messing with your pup, the elimination-challenge diet is generally the best option.

Veterinarians often recommend an elimination-challenge diet for patients suspected of having a food allergy. However, elimination-challenge diets are useful not only for confirming suspicions but also for treating the problem.

An elimination diet involves eliminating certain ingredients from your dogs diet in order to detect which food is causing an allergic reaction.

How Does An Elimination-Challenge Diet Work?

The principle behind an elimination-challenge diet is pretty simple, but implementing it requires some explanation. Well describe the basic steps below but understand that you should always work with your vet to devise the proper procedure for your pet.

Step 1: Eliminating Allergens

You begin implementing an elimination-challenge diet by trying to remove any potential allergens that may be present in your dogs food.

This generally means switching to a food that features a novel protein source, like:

Kangaroo, bison, pheasant, as well asvenison, are generally considered novel protein sources. Few dogs are exposed to these food sources as a matter of practice, so allergies are unlikely to have developed in response to them.

Other recommended hypoallergenic meat protein sources include:

A good elimination-challenge food usually draws its carbohydrate content from brown rice, sweet potato, or even possibly white potato, which rarely cause allergy problems for dogs the way wheat or corn may.

Additives, artificial flavors, yeast, and other supplements should also be kept to a minimum, to help reduce the chances of overstimulating the immune system.

Hopefully, the restricted diet will cause your dogs symptoms to disappear (although it may take several weeks before this occurs). This will allow her to get the nutrition she needs, without suffering from a constant allergic reaction. This can help your dog start to feel better and heal.

When practicing an elimination diet, the following requirements must be met:

• The dog must be fed a unique protein and carbohydratesource that the dog has not been previously exposed to.
• The dog must be kept on this diet for at least 12 weeks.
• Only the special diet and water can be consumednothing else! This means no rawhides, chews, treats, flavored toothpaste, or flavored medication.
• Keep an especially alert eye on your pooch during this time. Dont allow her to sneak into the trash or start chewing up something gross in the backyard, otherwise the process must be reset.
• Dont let your pooch in the dining room during meal times. Even a few crumbs dropped by a messy kiddo can force you to restart your dogs elimination diet.

Youll need to be vigilant, but all the work will be worth it when you finally know exactly what ingredients your pup is allergic to, allowing you to pick the best food for their needs and provide a better quality of life.

What if you have other dogs? Ideally, the easiest way to conduct the elimination diet when you own more than one dog is to do the diet with all the dogs. If thats not possible, feed the pooch you suspect of having allergies in a completely separate room from the other dogs.

After several weeks, its time for the next step: the challenge portion of the diet can begin.

Step 2: Reintroduction

If your dog begins to show a reduction or elimination of allergy symptoms after the 12 weeks, its time to reintroduce those problematic foods you suspect of causing your dogs allergies.

This may seem counter-intuitive since your dog is finally allergy-free. However, the reintroduction of suspected allergy-causing foods is required to confirm your suspicions.

During this portion of the treatment, you slowly add back one food item that you suspect might be an allergen. If no change occurs with the first added food item, you can add another, one at a time. When one of the food items cause allergic reactionssymptoms flare back up, you know which ingredients are to blame.

Then avoid those foods completely.

Its also important to remember that many dogs are allergic to more than one type of protein. This can complicate your efforts to determine the cause of your dogs allergies. You may need to test several ingredients.

Even with all that work, permanent safety is no guaranteeyour dog may eventually develop an allergic reaction to the new protein source after being fed it for a long period of time.

What About Blood Testing?

Elimination diets are a ton of work, so its no wonder owners often look to blood testing as a possible immediate solution to discovering what ails their pup.

Unfortunately, blood testing cant provide an accurate diagnosis for your dogs food allergies.

The good news is that intradermal skin testing is often helpful for diagnosing allergies. If you suspect your dog is suffering from allergies but are unsure what the cause is, intradermal skin testing is an option worth considering.

Since inhalant allergies are much more common than food allergies, skin testing may solve your issue.

What Exactly is a Hypoallergenic Dog Food?

Technically, the term hypoallergenic dog food is a bit misleading.

There is no such thing as a universal hypoallergenic dog foodits mainly a marketing term. This is because one type of dog food could be considered hypoallergenic for an individual dog, but not another.

For a dog allergic to chicken, any food that does not contain chicken would be considered hypoallergenic for that individual canine.

However, another dog may be allergic to pork rather than chicken. In this case, chicken-free dog food would not be hypoallergenic for that particular dog.

Often, manufacturers label foods as hypoallergenic when the recipe leaves out the most common allergens.However, because commonallergens can be avoided through various methods, there are several types of hypoallergenic dog foods.

The main forms of hypoallergenic dog foods include:

• Limited Ingredient Diet: Limited ingredient diets contain fewer ingredients than standard dog food. Because of the lower number of ingredients, its often easier to narrow down which ingredients are causing your dog problems.
• Novel Protein Diet: Novel protein diets introduce a unique protein that isnt commonly found in most traditional dog foods. Some popular novel proteins (as noted above) include kangaroo, pheasant, venison, and bison.
• Hydrolyzed Protein Diet: Hydrolyzed protein dog food diets break up the protein and carbohydrate molecules down into such small sizes that they wont trigger an allergic reaction in your dog.
• Prescription Diet: These specialized diets prescribed by veterinarians are specially designed to be hypoallergenic and can only be obtained through a veterinariansoffice.
• Homemade Food: Homemade food is often popular when conducting an elimination diet, due to the control owners have over proteins and ingredients. While great for identifying your dogs trouble ingredients, homemade food isnt an ideal long term solution, as its difficult virtually impossible for owners to craft a properly balanced diet. That being said, if you work with your vet and use a homemade dog food nutrient supplement pack, you can make some fantastic, nutritionally-appropriate hypoallergenic dog food.

Note that dog food can fit into more than one of these categories. For example, a hypoallergenic dog food relying on a novel protein source can also have limited ingredients.

Remember that you should look for single-source novel proteins and single-source carbohydrates (so for example, you would not want a food that uses pheasant as well as fish, or sweet potato as well as rice).

Common combinations include:

• Venison & Potato
• Duck & Peas
• Salmon & Sweet Potato
• Kangaroo & Brown Rice

Note: Lamb was once considered a novel protein, but has now become more common in dog foods. Still, if you havent fed your dog lamb before, it could be classified as a novel protein for your pooch.

Is Raw Food the Answer to Dog Food Allergies?

Some owners consider switching to a raw diet to alleviate their dogs food allergies.

While it is true that some raw proteins may have a slightly different configuration than cooked proteins, and these may prevent them from triggering an allergic reaction, no evidence has been collected yet to support such a conclusion.

In addition to the lack of substantial evidence for alleviating allergies, raw diets have a number of drawbacks that limit their appeal.

In fact, both the U.S. Food and Drug Administration and the American Veterinary Medical Association discourage pet owners from feeding raw meat to their pets.

The reasons for these recommendations are varied, but one of the most troubling problems is that raw meats often harbor a variety of bacteria, including Salmonella spp., E. coli and Clostridium spp., among others.

While homemade and raw diets sound all well and good, its actually quite difficult to compose a homemade or raw formula that will match the nutritional profile of a commercial dog food.This can lead to problems that are often worse than the allergy.

Homemade diets must be balanced with the right vitamins, supplements, and minerals, and that is exceedingly difficult for the average owner to accomplish.

If you do choose to go forward with a permanent homemade dog food, make sure to consult a veterinary nutritionist.

Generally speaking, it is wise to provide your dog with a nutritionally balanced, bacteria-free, commercially prepared, hypoallergenic diet if your dog suffers from food allergies.

Dont Forget to Use Hypoallergenic Treats Too

Even though they dont make up a huge percentage of your pups diet, treats can also trigger allergic reactions. Many treats are made from potential allergens, such as corn, wheat, chicken, pork or beef, and these could undermine your efforts to eliminate allergens from your dogs diet.

Fortunately, there are several hypoallergenic dog treats on the market, which are made of ingredients that are unlikely to trigger allergic reactions, such as pumpkin, sweet potato and duck.

Dietary allergies are often frustrating problems for both you and your pup, but they arent the end of the world. Work to determine the causal allergen and find a dog food that does not include it. With a little hard work, determination and perseverance, you can probably find a dog food that eliminates your dogs itchy skin.
