6 Scientifically Proven Foods That Can Cause Dog Allergies

 Is your Boxer dog scratching excessively, vomiting, or having diarrhea? These could be signs of a food allergy.

Based on data collected from 15 experimental studies from different continents, cited in Food Allergies, A Canine Review, and a veterinary article, Food Allergies in Dogs indicates the top 6 foods causing food allergies in dogs are

  • Beef
  • Dairy Products
  • Wheat
  • Lamb
  • Chicken Egg
  • Soy

The data from these studies showed beef, dairy products, and wheat accounted for 69% of reported cases of adverse food reactions.

Lamb, chicken egg, and soy accounted for 25% of adverse reactions in these studies.

Does this mean that you shouldn’t feed your boxer any products containing these ingredients? Not necessarily, but boxer dog allergies such as skin or gastrointestinal problems, may be caused by one of these culprits.

The only way to find out with some certainty is to do an 8-12-week elimination diet with your boxer.  Elimination diets will be discussed in further detail later in this article.

The best way to find out if these products are in your boxer’s food is to look at the product’s ingredient labeling.  Ingredients in the product in the highest amounts will be listed first on the label.

Dog Scratching

According to the National Institute of Allergy, a food allergy is defined as “the clinically abnormal exaggerated immunological reaction/response to the ingested allergen present in food”.

Food allergies are usually associated with an immune response related to the protein component being fed to your dog.

Food allergies show 

  • No age predisposition
  • No sex differences
  • No seasonal occurrences

In studies on dogs, German Shepherds and Labradors were found to have the highest incidence of food allergies, however, any breed of dog including mixed dog breeds can be affected by food allergies.

The incidence by age of dog showed

  • 33% of dogs less than 1 year old
  • 51% of dogs between 1 and 5 years old
  • 16% of dogs between 5 and 11 years old

What Causes Boxer Dog Food Allergies?

According to veterinarians Dr. Barnett, DVM, and Dr. Ward DVM of Pet Services, VCA Animal Hospitals, in their article Food Allergies in Dogs, a pet allergy occurs when the immune system overreacts and produces antibodies to foods they would usually tolerate.

Different Types of Dog Food Allergies and How They Develop

Food allergies are one of the most common types of allergies in dogs, affecting up to 10% of the canine population. A food allergy occurs when a dog’s immune system overreacts to a particular protein in their food. This can cause a variety of symptoms, including itchy skin, gastrointestinal upset, and respiratory problems.

The most common types of dog food allergies are to:

  • Beef
  • Chicken
  • Dairy
  • Eggs
  • Soy
  • Wheat

However, dogs can be allergic to any protein in their food, including proteins from fish, pork, lamb, and duck.

Food allergies typically develop over time, with repeated exposure to the allergen. The first time a dog eats a food containing the allergen, their immune system will produce antibodies to that allergen. When the dog eats the food again, the antibodies will bind to the allergen and release histamines, which cause the allergic reaction.

The severity of a dog’s food allergy can vary depending on the individual dog and the amount of allergen they are exposed to. Some dogs may have only mild symptoms, while others may have severe reactions that require medical attention.

Identifying and Treating Boxer Dog Food Allergies

The first step in identifying a food allergy in a dog is to rule out other possible causes of the dog’s symptoms. This may involve conducting a food trial, which involves feeding the dog a diet that is restricted to a single protein source and carbohydrate source for 6-8 weeks. If the dog’s symptoms improve on the food trial diet, it is likely that they have a food allergy to one of the proteins or carbohydrates that were excluded from the diet.

Once a food allergy has been identified, the best way to treat it is to avoid feeding the dog the allergen. This may require switching the dog to a hypoallergenic diet or a diet that is restricted to a specific protein source.

If you suspect that your dog may have a food allergy, it is important to talk to your veterinarian.

They can help you to identify the allergen and develop a treatment plan for your dog.

Top Symptoms of Boxer Dog Food Allergies

The symptoms of dog food allergies can vary depending on the individual dog and the severity of the allergy. However, the most common symptoms include:

Skin problems

  • Itching
  • Redness
  • Inflammation
  • Rashes
  • Hives
  • Hair loss
  • Licking and chewing of the paws, feet, and/or underarms

Gastrointestinal problems

  • Diarrhea
  • Vomiting
  • Gas
  • Abdominal pain
  • Blood in the stool

Respiratory problems

  • Sneezing
  • Coughing
  • Wheezing
  • Difficulty breathing

Other possible symptoms of dog food allergies include:

  • Weight loss
  • Lethargy
  • Hyperactivity
  • Behavioral changes
  • Ear infections

How to identify each allergy symptom

  • Itching: Dogs with food allergies often itch excessively, especially on their feet, ears, and underarms. You may also notice that your dog is licking and chewing at these areas.
  • Redness and inflammation: Red, inflamed skin is another common symptom of food allergies in dogs. The inflammation may be localized to a specific area of the body, or it may be more widespread.
  • Rashes and hives: Hives are raised, red bumps that can appear anywhere on the body. Rashes can be red, inflamed, and scaly.
  • Hair loss: Hair loss is a common symptom of food allergies in dogs, especially if the allergy is causing chronic itching.
  • Licking and chewing of the paws, feet, and/or underarms: Dogs with food allergies often lick and chew at their paws, feet, and/or underarms to relieve the itching. This can lead to hair loss, redness, and inflammation in these areas.
  • Diarrhea: Diarrhea is a common symptom of food allergies in dogs. The stool may be loose, watery, and/or bloody.
  • Vomiting: Dogs with food allergies may also vomit. The vomit may contain food, bile, or mucous.
  • Gas: Dogs with food allergies may experience excessive gas.
  • Abdominal pain: Dogs with food allergies may experience abdominal pain. This pain may be mild or severe.
  • Blood in the stool: Blood in the stool can be a sign of a serious medical condition, including food allergies. If you see blood in your dog’s stool, it is important to take them to the veterinarian immediately.
  • Weight loss: Dogs with food allergies may lose weight, even if they are eating a normal amount of food. This is because their bodies are wasting energy trying to fight off the allergic reaction.
  • Lethargy: Dogs with food allergies may be lethargic or tired. This is because their bodies are working hard to fight off the allergic reaction.
  • Hyperactivity: Some dogs with food allergies may become hyperactive. This is thought to be a coping mechanism for the discomfort caused by the allergic reaction.
  • Behavioral changes: Dogs with food allergies may experience behavioral changes, such as aggression, anxiety, and/or depression.
  • Ear infections: Dogs with food allergies are more likely to develop ear infections. This is because the inflammation caused by the allergy can create a moist environment in the ear canal, which is ideal for bacteria and yeast to grow.

If you notice any of these symptoms in your dog, it is important to take them to the veterinarian to rule out other possible causes and to develop a treatment plan.

Are Some Allergens More Likely To Cause Boxer Dog Food Allergies?

Beef

Drs. Barnett and Dr. Ward indicate in their article that the most common food allergens causing boxer dog allergies are

  • Beef
  • Dairy Products
  • Lamb
  • Chicken
  • Chicken Eggs
  • Soy

To support these findings, in a scientific review, Food Allergies in Canines, A Review –  Journal of Entomology and Zoology Studies, 2017 the authors report the findings on studies relating to dog food allergies.

15 experimental studies with 286 dogs across multiple continents examining ingredients that were commonly associated with food allergies reinforced the VCA article findings showing that

  • Beef, Dairy products, and Wheat accounted for 69% of all of the reported food allergy cases
  • Lamb, Chicken Egg, and Soy accounted for 25% of all reported allergy cases.

94% of all cases of food allergies in dogs were related to these 6 ingredients.

In another clinical trial, 25 dogs were fed specific food ingredients to determine f they experienced any adverse reactions.

The dogs were fed beef, chicken, chicken eggs, cow’s milk, wheat, soy, and corn.

Among all of the ingredients tested Beef and Soy were found to cause the most skin-related reactions.

All the ingredients caused at least one sign of allergy in at least one dog.

36% of dogs had an allergic reaction to at least one protein but the mean number of suspected food allergens was 2.4 per dog.

Boxer Dog Food Allergies – Elimination Trials

A dog food elimination trial is a process of feeding a dog a restricted diet for a period of time to identify the food or food component that is causing an allergic reaction. This is the most accurate way to diagnose a food allergy in dogs.

How to Conduct a Food Trial

  1. Choose a novel protein source and carbohydrate source. This means choosing a protein source that your dog has never eaten before, such as venison or rabbit. You should also choose a carbohydrate source that is different from the carbohydrate source in your dog’s current food, such as sweet potato or brown rice.
  2. Prepare a homemade diet or purchase a commercial hypoallergenic diet. A homemade diet is more likely to be successful, but it can be more time-consuming to prepare. If you choose to prepare a homemade diet, be sure to consult with a veterinarian or certified veterinary nutritionist to ensure that the diet is nutritionally complete and balanced.
  3. Feed your dog the restricted diet for 6-8 weeks. This is the amount of time it takes for your dog’s immune system to react to the allergen. During this time, your dog should only eat the restricted diet and drink water. Avoid giving your dog any treats, table scraps, or other foods that could contain the allergen.
  4. Monitor your dog’s symptoms. If your dog’s symptoms improve on the restricted diet, it is likely that they have a food allergy to one of the foods that were excluded from the diet. If your dog’s symptoms do not improve, it is possible that they have a non-food allergy, such as an environmental allergy or a flea allergy.

Once you have completed the food trial, you can start to reintroduce foods one at a time to see which food causes your dog’s symptoms to return. When reintroducing foods, start with a small amount of food and wait 24 hours to see if your dog has any reaction. If your dog does not have any reaction, you can gradually increase the amount of food you feed them. If your dog has a reaction, you know that they are allergic to that food.

Tips for Conducting a Food trial

  • Be consistent with the diet. It is important to feed your dog the restricted diet for the full 6-8 weeks, even if their symptoms improve sooner. This will help to ensure that you have accurately identified the allergen.
  • Keep a food diary. This will help you to track what your dog is eating and when they are having symptoms.
  • Be patient. It can take several weeks to identify the allergen.

If you are unsure about how to conduct a food trial, talk to your veterinarian. They can help you to choose a restricted diet and monitor your dog’s progress.
