How To Tell If Your Dog Is Allergic To Food

Our Backstory: Common Food Allergies For Dogs

Explaining Dog Food Allergies and Diet Trial

After Rascal turned a year old or so, he started developing really strange eating habits. He wasnt finishing his food, had loud intense stomachaches and frequently threw up. We went through a number of blood tests. He had been diagnosed with things like pancreatitis, anxiety and one vet even thought he had parvo. We were stressed and at a loss at how to move forward. That is until we did an allergy test.

We uncovered that Rascal was allergic to a dozen different food items, one being beef, the main ingredient in his traditional dry dog food. Our vet introduced us to an all-natural human-grade dog food company called Just Food for Dogs. The company sells premade food and teaches people how to make a homemade dog food recipe at home. Once we started this all-natural diet, the stomach aches subsided and he was the happiest we had ever seen him.

A Quick Word About Food Allergies Versus Food Intolerance

A food allergy isnt the exact same thing as a food intolerance. Food allergies are characterized by a genuine allergic reaction, which happens because your dogs immune system is hypersensitive to a protein contained in a particular food. The bodys immune cells produce immunoglobulin E antibodies when they encounter that protein, even though its actually harmless. These IgE antibodies bind to a receptor on the proteins surface, essentially treating it as if it were a virus or a parasitic microbe.

This sets off a series of immune system events that involve the release of histamine and other inflammatory compounds, causing itchiness, rashes, runny noses, and in severe cases, difficulty breathing and even anaphylaxis.

A food intolerance is a separate condition, and like food allergies, it can occur in dogs as well as in humans. Unlike allergies, food intolerances are not an immune reaction. They are usually caused by malabsorption of certain nutrients, or by the lack of certain enzymes needed to break down certain chemicals in food.

Food intolerances are far less acute and obvious than food allergies, and theyre also less dangerous. They can cause hives, respiratory symptoms, or gastrointestinal problems. Usually, the onset of the symptoms will be around half an hour to an hour after your dog eats the food, but in some cases, the onset can be delayed by as much as 48 hours.

Talk With Your Veterinarian

As always, talk to your veterinarian if you suspect that your dog may have allergies. They may perform tests to rule out more common or more serious diseases that can cause similar symptoms.

To decide whether allergies are likely the culprit, your veterinarian will also take into account:

  • The age of onset

  • Your dogs breed

Most Common Dog Food Allergens

“Meat, dairy, and eggs are often thought to be the most common dog food allergens,” says Shmalberg. “Yet generally, it’s the protein part of those foods that tend to be problematic, rather than, say, the meat itself.” Keep in mind, veggies can contain protein, so they’re not automatically safe.

That same review BMC Veterinary Research identified some of the most frequently reported dog food allergens involved in adverse food reactions. Here’s a look, from most-reported to least-reported.

Shmalberg calls out two important caveats to keep in mind here.

  • Newer research is needed. Many of the studies out there, and those sourced in this review, are older, when dog foods were being made and processed differently than they are today. Allergies tend to change over time along with foods, and as new studies emerge, we may see different allergens rising to the top of the list.
  • The more common a food is, the more likely the allergy. “For an allergy to a food to develop, a dog needs to be exposed to that food,” says Shmalberg. “That may explain why the proteins most commonly found in dog food, like beef and chicken, fall higher on the list.”

    What Is Inhalant Allergy And How Is It Treated


    The term inhalant allergy in the dog is often used as a synonym for atopy. The main inhalant allergens are tree pollens , grass pollens, weed pollens , molds, mildew, and house dust mites. Many of these allergies occur seasonally, such as ragweed, cedar, and grass pollens. However, others such as molds, mildew, and house dust mites occur year-round. When humans inhale these allergens, the resulting allergy primarily manifests with upper respiratory signs: runny eyes, runny nose, and sneezing . Although sometimes the symptoms of allergies include allergic rhinitis or bronchitis, in most dogs, inhalant allergy manifests with itchy skin . Due to these clinical signs, the condition is also called inhalant allergic dermatitis. The dog may rub its face, lick its feet and scratch the axillae .

    “Symptoms of atopy can be controlled but a permanent cure is not usually possible.”

    Most dogs that have inhalant allergy start showing signs between one and three years of age. Affected dogs will often react to several allergens and often experience concurrent flea or food allergies. If the offending allergens can be identified by intradermal skin tests or blood tests, the dog should be protected from exposure to them as much as possible. Because most of these allergens are environmental, this is difficult and recurrent bouts are likely. Symptoms of atopy can be controlled but a permanent cure is not usually possible.

    Allergy Symptoms In Dogs

    If your dog is experiencing symptoms like itchy ears and skin or stomach issues, theres a good chance your dog may have a food allergy.

    Allergies in dogs are usually genetic. When this issue is triggered, its because the dog came into contact with whatever it is he or she is allergic to. Environment can affect your dogs allergies but a genetic predisposition is almost always the root cause.

    According to pets webmd, 10% of all allergy cases in dogs are food allergies. Studies are still being conducted to determine just what causes some dogs to express the trait of food allergies.

    Itchy Skin Red Underbelly And Dull Coat

    Together, these signs can indicate an allergy. Your dog itches constantly without relief, possibly causing hair loss in the affected patches.

    What It Looks Like: Skin underneath the hair is red or pink, dry, and inflamed. No relief with baths, conditioners, or over-the-counter allergy medications. Excessive, near-constant scratching.

    What It Means: Environmental allergies or food allergies.

    But First! Rule Out

    Shampoo residue on your dogs skin is a leading cause of contact dermatitis, and often resolves by switching to a milder shampoo and rinsing thoroughly. Try this trick: Shampoo your dog, and rinse him until you think you are done. Then, rinse two more times to be safe!

    Shampoos containing artificial colors , sodium laurates, phthalates, mineral oil, and fragrances can all cause irritation. Try switching to a species-appropriate, all natural rinse for your dog, such as ones that contain apple cider vinegar or coconut oils.

    Pollen Allergy: Your dog may also have a pollen allergy: try wiping him down with a cool, damp cloth every time he comes inside to eliminate exposure to pollen.

    Fleas: Make sure your dog does not have fleas, as flea allergy dermatitis will also cause irritated skin.

    How Are Dog Food Allergies Diagnosed

    Diagnosing food allergies in dogs isnt always a straightforward process. Its not like theres a simple test that can instantly tell what your dog is allergic to or, if indeed, he has food allergies at all.

    You have to start at the beginning, with the help of your veterinarian, to know for sure whether your dogs skin or ear issues are caused by food allergies.

    What Signs Should I Watch Out For

    Unlike a human’s reaction to, say, a shellfish allergy, a dog’s food allergies are generally expressed as out-of-season itching. Common symptoms include red skin or rashes, particularly on the ears and feet. In some cases, allergies may cause a dog to develop gassiness, vomiting and diarrhea.

    Most commonly, these signs will appear before the dog’s first birthday, but a food allergy can develop at any point in an animal’s life.

    How To Help Dog Allergies And Allergy Medicine For Dogs

    Obviously, figuring out the exact cause of your dogs allergies and helping them avoid whatever that is is the best way to treat them. But even then, you should probably keep up with preventative measures to stop your pups itchiness for good. Finding the source of your dogs allergy and discussing a specific treatment plan with your veterinarian is recommended, Klein says.

    Here are the ways in which dog allergies are most often treated:

    Antihistamines: Yeah, like Benadryl vets often use it for dogs with mild allergies. This treatment is generally inexpensive and safe with little side effects, but different types can have variable effects and dont work on all dogs, Klein says. Just make sure to contact your veterinarian before giving your dog any form of medication, so they can guide you on the right dosage and whatnot.

    Flea Prevention: Flea prevention is obvious, relatively easy and will help dogs who suffer from allergies to fleas, Klein says. Seriously, flea prevention is super easy to keep up with even if only for the sake of keeping your home free of fleas and there are tons of great products out there.

    Environmental and External Aids: Air purifiers can help reduce certain molds that may trigger allergies in dogs, Klein notes. Dusts and pollens are best controlled by using an air cleaner with a HEPA filter. An added bonus of having an air purifier: You get to breathe fresh air, too!
