Inflamed skin, hot spots, ear infections, chronic diarrhea, upset stomach, and constant scratching. If even a few of these symptoms sound like your dog, the odds are pretty good they are suffering from some kind of food allergy or intolerance.
If you’re at a loss of how to help your pup find some relief, you’ll want to keep reading.
In this article, we’ll discuss how to tell if your dog has a food allergy or sensitivity and then outline the best way to use an elimination diet to nail down exactly which food it is that’s making your pet so miserable. Then we’ll review our top five picks of the best dog foods for allergies to help you and your dog find some much-needed relief.
What Causes Allergies In Dogs
If you’ve ever suffered from allergies, you know what it feels like. For humans, it usually means a running nose, itchy eyes, constant sneezing, and maybe even swelling in the throat and face.
But allergies affect dogs in a much different way.
Mast cells are the part of the immune system that is responsible for allergic reactions. In humans, the bulk of these cells lie in the respiratory tract, but in dogs, most mast cells exist in the gut, and by extension, the skin.
This means that, while a human who consumes a food they are allergic to will often show signs like difficulty breathing and swelling in the face, a dog will typically show signs like diarrhea, vomiting, and itchy skin.
In fact, the most common cause of dermatitis in dogs is allergies. And food sensitivities and intolerances can also cause itching.
The most common food allergies in dogs, listed in order, are beef, dairy, chicken, wheat, soy, lamb, corn, and eggs, according to a study by BMC Veterinary Research.
But how do you know if your dog is suffering from a food allergy or sensitivity or if they are allergic to something in the air like dust or pollen?
If your dog’s itching comes and goes with the seasons, then odds are they are suffering from an environmental allergy. But, if they have digestive issues in addition to itching or their itching remains constant even during travel or with the use of air purifiers and filters, there is a good chance they are reacting to something in their diet.
Dog Food Elimination Diet
While there are blood and skin tests to determine what a dog is allergic to, these tests tend to be very inaccurate for food allergies and completely useless for sensitivities and intolerances.
Instead, the best way to determine if your dog is suffering from a food allergy or intolerance is to do an elimination diet.
In an elimination diet, you remove all possible allergens from a dog’s diet. If their symptoms subside after a set period of time, then you can be relatively sure one of the ingredients you eliminated was the culprit.
First, List All Possible Allergies
Before you begin an elimination diet for your pooch, you need to make a list of all possible foods your dog is allergic to. But how do you know what your dog might be allergic to?
Easy. They can be allergic to literally anything they have consumed in the past.
That means you need to list every ingredient in their current dog food and any past dog foods you are aware of, as well as ingredients in their treats, human food they have been given, flavors in their medication and any other food product they have consumed.
Next, Find a New Diet Without Possible Allergens
Once you have a full list of potential allergen foods, then your rather difficult task is to find a dog food that doesn’t contain any of those ingredients.
Below, we have included many limited ingredient dog food reviews. This would be a great place to start looking for a new food that might work for your dog.
The best limited ingredient dog foods (LID) for this new trial diet should have only one protein source and one starch. On this ingredients label, you should see something like “salmon, peas” and then a long list of vitamins and minerals.
Make sure neither the listed protein or starch are on your possible allergen list. And that the remaining ingredients are also free of any potential allergens.
Slowly transition your dog to the new diet and be sure they are not receiving any treats, table scraps, or even medications that contain ingredients on your list.
If your dog suffers from digestive issues due to a food allergy, you should see symptoms clear within two weeks, according to Whole Dog Journal. For dogs who suffer from allergy induced itchy skin, it is likely to take much longer, even up to three months for symptoms to clear.
Make sure you wait at least three months before deciding if the new diet helped your dog. If their symptoms remain the same, find a different LID and repeat the process.
If your dog is still showing symptoms, then it is likely their issues are caused by some other type of allergy or disease.
But, if your dog’s symptoms do clear on the new diet, then you can start to celebrate because you are well on your way to figuring out exactly what your dog is allergic to.
Finally, Reintroduce Possible Allergens
Many people are happy to stop the trial diet process here. They’ve found a food that works well for their dog and they are fine with leaving that long list of ingredients out of their dog’s diet for the rest of the dog’s life.
Luckily, at least the best LID dog foods provide balanced and complete nutrition and can be fed long term. If you are happy with where your dog is at on their new diet, then there is little harm in stopping here.
But, the healthiest dogs eat a variety of different foods and your allergy-prone dog should have that option as well. If you want to be able to offer your dog a variety of different foods or just need to find a less expensive protein that they can eat, then you’ll need to continue with the elimination diet process.
Once your dog’s symptoms have ceased, then it is time to reintroduce one ingredient from their possible allergens list. You can do this by finding a new dog food that includes the previous two ingredients you were feeding plus the one you want to introduce, or you can add the test ingredient in whole form to the current food you’re using.
Once you start adding the test ingredient to your dog’s diet, you’ll need to wait at least a month to see if their symptoms return.
If not, then you can add a second test ingredient into their diet and repeat the process. If the allergy symptoms do return, then you can be relatively certain that your dog is allergic to that test ingredient.
If that’s the case, you should remove that ingredient from their diet again, wait until symptoms subside and then continue testing the ingredients on your list one at a time to make sure your dog doesn’t have any additional food allergies.
How to Choose a Quality Hypo-Allergenic Food
Once you have figured out exactly what all your dog is allergic to, then you can start hunting for a new complete diet to feed them.
When choosing the best dog food for allergy-prone dogs, the first thing you’ll need to do is thoroughly read the ingredients list. Any food can work for a dog with allergies so long as it doesn’t contain ANY ingredients they are allergic to.
The best dog food for sensitive skin and dogs with sensitive systems is one that is all-natural and not overly processed.
Most importantly, remember that the best allergy-free dog food for one pup may not be the best dog food for allergies in another pup. The most important thing is what’s in a dog food, not how it’s marketed or who it’s marketed to.
Below, we have picked the top five best dog food brands for allergies and food intolerances. These foods made our list because they contain limited ingredients, novel proteins, and novel plant ingredients.
Our hope is that you will be able to find a quality food that will work around your dog’s allergies and help them find some relief.
