Allergies Vs. Sensitivities: Decoding Your Dogs Reactions

Understanding Allergies and Sensitivities in Dogs

Allergies and sensitivities are common issues that dogs may experience, and understanding the difference between the two can help you better care for your furry friend.

Definition of Allergies

Allergies in dogs occur when their immune system overreacts to certain substances, also known as allergens. These allergens can be found in food, the environment, or even medications. When a dog with allergies comes into contact with these substances, their immune system releases histamines, causing a variety of symptoms.

Definition of Sensitivities

On the other hand, sensitivities in dogs are similar to allergies, but the reactions they trigger are slightly different. Sensitivities can occur when a dog has a specific intolerance or sensitivity to certain substances, such as ingredients in their food or environmental factors. These sensitivities may cause discomfort and negative reactions, but they aren’t typically as severe as allergies.

Differentiating between Allergies and Sensitivities

Differentiating between allergies and sensitivities can be challenging since the symptoms tend to overlap. However, there are some key differences to look out for. Allergies often result in more severe and immediate reactions, such as intense itching, hives, or difficulty breathing. Sensitivities, on the other hand, may cause milder symptoms over time, such as digestive issues, intermittent itching, or chronic ear infections. It’s essential to consult with your veterinarian for an accurate diagnosis to provide the appropriate treatment for your dog’s specific condition.

Common Allergens and Sensitivities in Dogs

Understanding the common allergens and sensitivities that can affect dogs will help you identify potential triggers and make necessary adjustments to their environment or diet.

Food Allergens

Food allergies are one of the most common types of allergies in dogs. Some common food allergens for dogs include beef, chicken, dairy products, wheat, soy, and corn. It’s important to note that dogs can develop allergies to any type of food, so identifying the specific allergen may require a process of elimination or allergy testing.

Environmental Allergens

Environmental allergens can also cause allergies and sensitivities in dogs. These allergens may include pollen, mold, dust mites, and even certain types of grass or plants. When dogs come into contact with these allergens, they may experience symptoms like itching, sneezing, watery eyes, or skin irritations.

Common Sensitivities

Aside from allergies, dogs can also develop sensitivities to various substances. Common sensitivities may include certain detergents or cleaning products, fragrances, pesticides, or even materials like wool or nylon. Identifying and eliminating these triggers can help alleviate your dog’s discomfort and prevent further sensitivities from developing.

Symptoms of Allergies and Sensitivities in Dogs

Recognizing the symptoms of allergies and sensitivities in dogs is crucial for early detection and prompt intervention. Here are some common symptoms to watch out for:

Skin-related Symptoms

Skin-related symptoms are one of the most common signs of allergies or sensitivities in dogs. These may include excessive itching, redness, rashes, hot spots, hair loss, or recurrent ear infections. Dogs with allergies may frequently scratch or lick certain areas of their body, leading to skin infections or irritations.

Respiratory Symptoms

Respiratory symptoms may occur when a dog inhales or comes into contact with airborne allergens. Some common respiratory symptoms include sneezing, coughing, wheezing, nasal discharge, or difficulty breathing. These symptoms may be more prevalent during specific seasons or in certain environments that contain high levels of allergens.

Digestive Symptoms

Food allergies and sensitivities often manifest through digestive symptoms. Dogs may experience vomiting, diarrhea, excessive gas, bloating, or changes in appetite. Chronic digestive issues can lead to weight loss, malnutrition, and a general decline in your dog’s overall health if left untreated.

Diagnosing Allergies and Sensitivities in Dogs

If you suspect that your dog has allergies or sensitivities, it’s crucial to consult with your veterinarian for an accurate diagnosis. Here are some common methods used to diagnose allergies and sensitivities in dogs:

Veterinary Exam

During a veterinary exam, your veterinarian will perform a thorough physical examination of your dog and gather information about their medical history and symptoms. They may inquire about any recent changes in diet, environment, or exposure to potential allergens.

Skin and Blood Tests

Skin and blood tests are commonly used to diagnose allergies in dogs. Skin tests involve injecting small amounts of different allergens under the skin to observe any reactions. Blood tests, such as enzyme-linked immunosorbent assay (ELISA) or radioallergosorbent testing (RAST), measure the levels of specific antibodies in the blood to identify potential allergens.

Elimination Diet

In some cases, an elimination diet may be recommended to identify food allergies or sensitivities. This process involves feeding your dog a hypoallergenic diet that consists of novel protein and carbohydrate sources. Gradually, potential triggers are reintroduced one at a time to observe any adverse reactions. This helps pinpoint specific dietary components causing allergies or sensitivities.

Treating Dog Allergies and Sensitivities

Once your dog’s allergies or sensitivities are diagnosed, several treatment options can help manage their condition and provide relief from symptoms. Your veterinarian may recommend one or a combination of the following approaches:


If the source of your dog’s allergies or sensitivities can be identified, avoiding exposure to those triggers is the most effective way to manage their condition. This may involve changing their diet, using hypoallergenic products, minimizing exposure to environmental allergens, or creating a safe and allergy-friendly living environment.


Medications may be prescribed to alleviate your dog’s symptoms and reduce the immune system’s response to allergens. Common medications used for allergies and sensitivities in dogs include antihistamines, corticosteroids, or immune-modulating drugs. It’s important to follow your veterinarian’s instructions and monitor your dog closely for any side effects.


Immunotherapy, also known as allergy shots, can be a long-term solution for some dogs with allergies. This treatment involves gradually exposing your dog to small amounts of the allergen to desensitize their immune system. Over time, this can reduce your dog’s sensitivity to the allergen and alleviate their symptoms. Immunotherapy requires close collaboration with your veterinarian and regular monitoring to ensure its effectiveness.

Preventing Allergies and Sensitivities in Dogs

While it may not be possible to prevent all allergies and sensitivities in dogs, there are steps you can take to minimize the risk or severity of these conditions. Here are some preventive measures you can implement:

Choosing the Right Diet

Selecting a high-quality, balanced diet that meets your dog’s specific nutritional needs is crucial in preventing allergies and sensitivities. Look for limited ingredient diets or hypoallergenic formulas if your dog has a history of allergies or sensitivities. Avoid common allergens and consult with your veterinarian for dietary recommendations.

Maintaining a Clean Environment

Keeping your dog’s environment clean can minimize exposure to allergens and reduce the risk of sensitivities. Regularly clean and vacuum your home, wash your dog’s bedding frequently, and use hypoallergenic cleaning products. Additionally, ensure your dog’s living area is well-ventilated to prevent the buildup of allergens.

Regular Veterinary Check-ups

Regular veterinary check-ups are essential for monitoring your dog’s overall health and detecting any potential allergies or sensitivities early on. Your veterinarian can provide guidance on preventive measures, including vaccinations, parasite control, and dietary recommendations to support your dog’s immune system.
