Is your German Shepherd constantly suffering from digestive issues and skin problems? If so, food allergies could be the hidden culprit behind their discomfort. These allergies can wreak havoc on your furry friend’s well-being, causing a range of health concerns.
Food allergies in dogs can manifest as skin irritation, gastrointestinal problems, or even chronic ear infections. The culprits behind these reactions can be found in common ingredients like beef, chicken, grains, or dairy products.
It’s essential for proud GSD parents like us to understand the signs and symptoms of food allergies so we can take proactive measures to alleviate our child’s discomfort.
So, in today’s post, we will discuss effective strategies to manage these allergies and ensure our pup lives a happy, healthy life.
What is a Food Allergy in Dogs?
A food allergy in dogs occurs when a dog’s immune system reacts abnormally to certain proteins present in their diet. The immune system identifies these proteins as harmful invaders and responds by releasing chemicals, such as histamines, to protect the body. This immune response can lead to various symptoms and health issues. (Source)
Common signs of food allergies in dogs include:
- Skin issues: Itchy skin, redness, hives, or inflammation.
- Gastrointestinal problems: Vomiting, diarrhea, or excessive gas.
- Ear infections: Chronic ear inflammation or infections.
- Respiratory symptoms: Sneezing, coughing, or wheezing.
It’s important to distinguish between food allergies and food intolerances. Food allergies involve an immune system response, while intolerances typically result from a lack of certain digestive enzymes and don’t involve the immune system.
Common food allergens for dogs include beef, dairy, chicken, lamb, fish, eggs, soy, and wheat.
Symptoms of German Shepherd Food Allergies
If you suspect that your German Shepherd may have a food allergy, keep an eye out for these common symptoms:
1. Frequent itching, scratching, or biting at their skin
If you notice your dog constantly licking or chewing on their paws, legs, or any other part of their body, it could be a clear indication of a food allergy.
This constant itchiness can lead to redness, inflammation, and even open sores on their skin.

Which are the common food allergens for German Shepherds?
Identifying and avoiding common food allergens is crucial to keeping your German Shepherd healthy and happy. Here are some of the most common food allergens for German Shepherds:
1. Proteins
- Beef: Beef is a common protein source in many dog foods. Allergies to beef can manifest as skin issues, digestive problems, and ear infections.
- Chicken: Chicken allergies are also relatively common. Dogs may exhibit similar symptoms as with beef allergies, including itching, gastrointestinal upset, and ear infections.
- Lamb: Although considered a novel protein source in some hypoallergenic diets, lamb can still be an allergen for some dogs.
2. Grains
- Wheat: Wheat is a common allergen for dogs, and gluten intolerance can lead to digestive issues. Some dog owners opt for grain-free diets to address potential sensitivities.
- Corn: Corn is another grain that some dogs may be allergic to. It’s often used as a filler in commercial dog foods.
3. Dairy
- Lactose: Many dogs are lactose intolerant, meaning they lack the enzyme needed to properly digest lactose found in milk and dairy products. This can lead to gastrointestinal upset.
4. Artificial Additives
- Preservatives: Artificial preservatives, such as BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene), can cause allergic reactions in some dogs.
- Colorings and Flavorings: Artificial colors and flavors are sometimes added to enhance the palatability of dog food, but they can trigger allergies in sensitive individuals.
5. Common Fillers
- Soy: This study found that soy is sometimes used as a protein source or filler in dog food. It can be an allergen for certain dogs.
- Corn: In addition to being a grain, corn is also used as a filler in some dog foods and treats. Dogs with corn allergies may experience itching and digestive issues.
6. Fish
- Salmon and Other Fish: Fish, including salmon, is a common ingredient in many dog foods. While fish is an excellent source of omega-3 fatty acids, some dogs may be allergic to it, leading to skin problems and gastrointestinal disturbances.
Remember, every dog is unique, and what may be an allergen for one German Shepherd may not affect another. If you suspect that your German Shepherd has a food allergy, it’s important to consult with your veterinarian for proper diagnosis and guidance.
They can help you create a suitable diet plan that avoids allergens and meets your dog’s nutritional needs.
How to diagnose food allergies?
To accurately diagnose food allergies in dogs, veterinarians employ various diagnostic methods. These methods help identify the specific allergens causing adverse reactions in our furry friends.
Let’s take a closer look at how veterinarians go about diagnosing food allergies in dogs.
1. Elimination Diets
One of the primary methods used by veterinarians to diagnose food allergies is through elimination diets. This process involves removing potential allergens from the dog’s diet and gradually reintroducing them while closely monitoring any allergic reactions. Here’s how it works:
- The veterinarian will recommend a hypoallergenic diet that contains novel protein sources and carbohydrates that the dog has not been exposed to before.
- The dog will be put on this special diet for a period of 8-12 weeks, during which time their symptoms should improve if they have a food allergy.
- After this initial period, individual ingredients are reintroduced one at a time to determine which ones provoke an allergic response.
- By carefully observing the dog’s reaction to each ingredient, veterinarians can pinpoint the specific allergens causing the adverse reactions.
Elimination diets are considered highly effective because they provide concrete evidence of food allergies by directly linking symptoms with specific dietary components.
Blood Tests
In addition to elimination diets, veterinarians may also use blood tests as part of their diagnostic approach for food allergies in dogs.
These tests measure specific antibodies or allergen-specific immunoglobulin E (IgE) levels to identify potential allergens triggering an immune response within the dog’s body.
There are two commonly used types of blood tests:
- Serum Allergen-Specific IgE Test: This test measures IgE levels in response to specific allergens present in a panel of common foods or environmental triggers.
- Food Sensitivity Test: This test measures IgG and IgA antibodies to identify potential food sensitivities that may be causing adverse reactions.
While blood tests can provide valuable information, it’s important to note that they may not always yield definitive results.
False negatives and false positives are possible, which is why they are often used in conjunction with elimination diets for a more accurate diagnosis.
3. Intradermal Skin Testing
This involves injecting small amounts of potential allergens under your dog’s skin and observing their reaction. If a raised bump or redness occurs at the injection site, it suggests an allergic response to that particular allergen.
Treatment of Food Allergies in German Shepherds
To effectively manage food allergies in German Shepherds, it is crucial to avoid the identified allergens. By eliminating these triggers from their diet, you can help alleviate their symptoms and improve their overall well-being.
There are various treatment options available that can further aid in managing allergies in German Shepherds.
1. Veterinary Consultation
If you suspect your dog has a food allergy, the first step is to consult with a veterinarian. The vet will conduct a thorough examination, consider the dog’s medical history, and may recommend diagnostic tests to confirm the presence of a food allergy.
2. Elimination Diet
The most common method for identifying food allergies in dogs is through an elimination diet. This involves feeding the dog a novel protein and carbohydrate source that they have not been exposed to before.
Common choices include venison, rabbit, duck, or other novel proteins, along with a carbohydrate like sweet potato or pea.
3. Hydrolyzed Diets
Hydrolyzed diets involve proteins that have been broken down into smaller components, making them less likely to trigger an allergic response.
These diets are designed to be hypoallergenic and can be a useful option for dogs with food allergies.
4. Limited-Ingredient Diets (LID)
Limited-ingredient diets contain a minimal number of ingredients, reducing the likelihood of triggering an allergic reaction.
These diets often feature novel protein and carbohydrate sources and avoid common allergens.
5. Home-Cooked Diets
Some pet owners choose to prepare home-cooked meals for their dogs using ingredients known to be hypoallergenic.
This allows for better control over the dog’s diet, but it’s essential to ensure the diet is nutritionally balanced.
6. Avoidance of Allergens
Once the allergen is identified, it’s crucial to eliminate it from the dog’s diet completely. This includes avoiding treats, table scraps, and any other sources of the allergen.
7. Supplements
In some cases, veterinarians may recommend supplements such as omega-3 fatty acids to support skin health and reduce inflammation associated with allergies.
8. Prescription Medications
In severe cases, where the dog is experiencing significant discomfort or complications, veterinarians may prescribe medications such as antihistamines, corticosteroids, or immunosuppressants to manage symptoms.
However, these are typically short-term solutions due to potential side effects.
9. Immunotherapy
Immunotherapy, also known as allergy shots or desensitization therapy, is another option for treating allergies in German Shepherds. This treatment involves injecting small amounts of specific allergens into your dog’s body over time.
The goal is to gradually desensitize their immune system and reduce their sensitivity to those particular allergens.
It’s important to note that the effectiveness of the treatment plan may vary from one dog to another. Patience is key, as it may take several weeks on a new diet to see improvements. Additionally, strict adherence to the prescribed diet is crucial to prevent accidental exposure to the allergen.
