Allergies in dogs are more common than you might think, and they can cause a range of issues, from mild discomfort to severe health problems. Just like humans, dogs can be allergic to a variety of things, including certain foods, environmental factors, and parasites like fleas. 

These allergies can lead to skin irritation, digestive issues, and other health problems that can greatly affect your dog’s quality of life.

Dog Allergy Alleviation

Addressing your dog’s allergies is incredibly important, not only to relieve their discomfort but also to prevent secondary infections and other health issues that can arise if left untreated. 

Allergies can also be a sign of an underlying issue, so it’s essential to get a proper diagnosis and treatment plan from your veterinarian.

In this blog, we will discuss the common symptoms of allergies in dogs, the different types of allergies, and how to manage and prevent them to keep your furry friend happy and healthy. Let’s get started!

Understanding Common Allergies in Dogs

Allergies in dogs can manifest in various ways and can be triggered by different factors. Here are some of the most common types of allergies in dogs:

Food Allergies

Food allergies are caused by an immune system reaction to one or more ingredients in a dog’s diet. Common food allergens for dogs include beef, dairy, wheat, egg, chicken, lamb, soy, pork, rabbit, and fish. 

Symptoms of food allergies can include itching, ear infections, skin infections, and gastrointestinal issues like diarrhea and vomiting. It’s essential to identify the specific ingredient causing the allergy, which often involves feeding a hypoallergenic diet and gradually reintroducing different ingredients to see which one triggers a reaction.

Environmental Allergies

Also known as atopic dermatitis, environmental allergies are caused by an allergic reaction to substances in the environment. Common environmental allergens for dogs include pollen, grass, mold, dust mites, and dander. 

Symptoms can include itching, redness, and skin infections. These allergies can be seasonal or year-round, depending on the allergen.

Contact Allergies

Contact allergies, also known as contact dermatitis, are caused by direct contact with an allergen. Common contact allergens for dogs include carpet fibers, plastic, laundry detergent, and chemicals found in shampoos and other grooming products. 

Symptoms of contact allergies can include redness, itching, and skin irritation at the point of contact.

Flea Allergy Dermatitis

An allergy to flea saliva, known as flea allergy dermatitis, is the predominant skin ailment among pets. Just one bite from a flea has the potential to cause significant itching, redness, and swelling. Failure to address this can result in loss of fur and subsequent skin infections.

Symptoms of Allergies

Recognizing the signs of allergies in your dog is crucial for early intervention and treatment. Although, a few symptoms of certain allergens are mentioned above, here are some common symptoms associated with allergies in dogs:

Itching and Scratching

Symptoms of Allergies in Dogs

This is often the most noticeable sign of an allergy. Your dog may constantly scratch, bite, or lick their skin, especially around the ears, paws, and rear end.

Red, Inflamed Skin

The skin may appear red, inflamed, and irritated, especially in areas that your dog has been scratching.

Hair Loss

Excessive scratching and biting can lead to hair loss in affected areas.

Ear Infections

Repeated ear infections can be a sign of food allergies or environmental allergies.

Watery Eyes or Runny Nose

Just like in humans, allergies in dogs can cause watery eyes or a runny nose.

Sneezing or Coughing

Some dogs with allergies may sneeze or cough frequently.

Vomiting or Diarrhea

Gastrointestinal issues like vomiting or diarrhea can be a sign of food allergies.


Swelling of the face, ears, lips, eyelids, or earflaps can be a sign of an allergic reaction.

Diagnosing Allergies in Dogs

If you suspect your dog has an allergy, getting a professional diagnosis is crucial. Here’s why:

Importance of Professional Diagnosis

Allergies in dogs can present with symptoms that are similar to other health conditions. For example, itching and skin irritation can also be caused by parasites like fleas or mites, bacterial or fungal infections, or other skin conditions. 

A proper diagnosis is essential to rule out other possible causes and to determine the best course of treatment.

How to Get a Proper Diagnosis

A proper diagnosis involves a thorough examination by a veterinarian. Your vet will take a detailed history of your dog’s symptoms, diet, and environment. They will also perform a physical examination to check for signs of allergies or other health issues. 

Your vet may recommend additional tests, such as blood tests or skin tests, to help identify the cause of your dog’s symptoms.

Allergy Tests

Blood Tests: A blood test can measure the level of certain antibodies (IgE) in your dog’s blood that are produced in response to allergens. 

However, this test is not always definitive, as some dogs with allergies may not have elevated IgE levels, and some dogs without allergies may have elevated IgE levels.

Intradermal Skin Test: This is considered the gold standard for diagnosing environmental allergies in dogs. Small amounts of common allergens are injected into the skin, and the reaction is observed.

If your dog is allergic to a specific substance, it will develop a small raised bump at the injection site.

It’s important to note that there is no definitive test for food allergies in dogs. The most reliable way to diagnose food allergies is through an elimination diet.

Allergy Tests in Dogs

In this type of test, your dog is fed a diet with a limited number of ingredients that they have not been exposed to before. If their symptoms improve, ingredients are gradually reintroduced to identify the culprit.

Treatment Options For Dog Allergies

Once your dog has been diagnosed with an allergy, the next step is to develop a treatment plan. 

The goal of treatment is to reduce or eliminate symptoms, prevent secondary infections, and improve your dog’s quality of life. Here are some common treatment options for dog allergies:


Antihistamines: These are drugs that block the effects of histamine, a chemical released by the body during an allergic reaction that causes itching and inflammation. 

Corticosteroids: These are anti-inflammatory drugs that can help reduce itching and inflammation. However, they can have side effects, especially with long-term use, so they are usually used for short periods or as a last resort.

Immunosuppressive Drugs: These are drugs that suppress the immune system and can be used to treat severe allergies. However, they also have potential side effects and are usually reserved for severe cases.

Topical Medications: These are creams, ointments, or sprays applied directly to the skin to relieve itching and inflammation.

Lifestyle Changes

Diet: If your dog has a food allergy, it will be necessary to change their diet to avoid the allergen. Your vet may recommend a hypoallergenic diet or a home-cooked diet with specific ingredients.

Environment: For environmental allergies, it’s important to minimize your dog’s exposure to the allergen as much as possible. This may involve keeping your dog indoors during certain times of the year, using air purifiers, or regularly cleaning your home to remove allergens.

Treatment Options For Dog Allergies

Natural Remedies

Omega-3 Fatty Acids: These are natural anti-inflammatory agents that can help reduce itching and inflammation. They can be found in fish oil supplements or flaxseed oil.

Aloe Vera: Aloe vera gel can be applied to the skin to help soothe and heal inflamed areas.

Oatmeal Baths: Oatmeal has natural anti-inflammatory properties and can help soothe itching and irritation. Make sure to use colloidal oatmeal (oatmeal that has been ground into a fine powder) and not regular oatmeal.

It’s important to remember that while these treatments can help manage your dog’s symptoms, they may not cure the allergy.

Dietary Considerations

The food that your dog eats plays a crucial role in managing their allergies. Some dogs are allergic to certain ingredients found in commercial dog foods, and in such cases, diet modification is a key component of treatment.

Identifying Food Allergies

Elimination Diets: An elimination diet is the most reliable method for identifying food allergies in dogs. This involves feeding your dog a diet that contains a limited number of ingredients that they have not been exposed to before. 

Typically, this will be a protein and a carbohydrate source that your dog has never eaten. You will need to feed your dog this diet exclusively for a period of 8-12 weeks. 

If your dog’s symptoms improve during this time, it suggests that something in their previous diet was causing the allergy. After this, you can gradually reintroduce ingredients one at a time to identify the culprit.

Reading Food Labels: It’s important to carefully read the labels of any commercial dog food you purchase. Many commercial dog foods contain a mix of different proteins and carbohydrates, making it difficult to identify the cause of an allergy. 

Additionally, some dog foods may contain additives or preservatives that can trigger an allergic reaction in sensitive dogs. Look for dog foods with a short ingredient list and avoid those with artificial colors, flavors, or preservatives.

Recommended Dog Foods for Allergies

Grain-Free Options: Grains are a common allergen for dogs, and some dogs may benefit from a grain-free diet. However, it’s important to note that grain-free does not mean carbohydrate-free. 

Many grain-free dog foods substitute grains with other carbohydrates like potatoes or legumes.

Dietary Considerations in Dogs

Single-Protein Foods: Some dogs are allergic to specific proteins, such as beef, chicken, or dairy. In such cases, feeding a single-protein diet can help identify and manage the allergy. 

For example, if you suspect your dog is allergic to chicken, you can try feeding a diet that contains a single, alternative protein source, like fish or lamb.

Wet vs. Dry Food: There is no one-size-fits-all answer to whether wet or dry food is better for dogs with allergies. Some dogs may prefer wet food, while others may prefer dry food. 

It’s important to choose a high-quality food that meets your dog’s nutritional needs, regardless of whether it is wet or dry. If you are unsure, consult your veterinarian for a recommendation.

Daily Care Tips

Managing your dog’s allergies is a daily commitment. By implementing a few daily care tips, you can help keep your dog comfortable and minimize their exposure to allergens.

Bathing and Grooming

Frequency: Bathing your dog regularly can help remove allergens from their coat and skin. However, bathing too frequently can dry out your dog’s skin and cause irritation. 

The ideal frequency of bathing will depend on your dog’s specific needs and the severity of their allergies. Your veterinarian can help you develop a bathing schedule that is appropriate for your dog.

Types of Shampoos and Conditioners: Not all pet shampoos and conditioners are created equal. Some products may contain fragrances, dyes, or other ingredients that can irritate your dog’s skin or trigger an allergic reaction. 

It’s important to use hypoallergenic shampoos and conditioners that are specifically formulated for dogs with sensitive skin. Your veterinarian can recommend products that are suitable for your dog.

Exercise and Play

Safe Materials for Toys: Just like with cleaning products, some materials used in dog toys can cause allergic reactions. Look for toys made from natural, hypoallergenic materials. 

Additionally, some dogs may be allergic to latex or rubber, so be mindful of the materials used in your dog’s toys.

Exercise Considerations for Dogs with Allergies: Exercise is important for all dogs, but it can be a bit more challenging for dogs with allergies.

For example, if your dog is allergic to grass, you may need to find alternative exercise options, such as playing fetch on a paved surface or indoor play.

Daily Care Tips

Additionally, if your dog has skin allergies, swimming may help soothe their skin but be sure to rinse them off thoroughly afterward to remove any chlorine or salt.

Preventative Measures

Keeping your dog healthy involves not only managing existing allergies but also taking steps to prevent future problems. Here are some preventative measures you can take to help keep your dog healthy and comfortable.

Regular Check-ups

Importance of Keeping Veterinary Appointments: Regular veterinary check-ups are crucial for all dogs, but especially for those with allergies. 

Your veterinarian can monitor your dog’s condition, adjust their treatment plan as necessary, and catch any new issues before they become more serious. 

Make sure to keep all scheduled appointments and consult your veterinarian if you notice any new symptoms or changes in your dog’s condition.

Routine Blood Tests: Routine blood tests can help your veterinarian monitor your dog’s overall health and identify any potential issues early on. 

For dogs with allergies, blood tests can also help identify any underlying conditions that may be contributing to their symptoms.


Allergy Shots: Allergy shots, or immunotherapy, is a treatment option for dogs with certain types of allergies. This involves injecting small amounts of the allergen(s) to which your dog is allergic, in order to help their immune system build up a tolerance. 

This treatment is usually reserved for dogs with severe allergies that do not respond to other forms of treatment.

Pros and Cons: Immunotherapy can be very effective for some dogs, but it is not suitable for all dogs or all types of allergies. The treatment usually takes several months to start working and may need to be continued indefinitely. 

Some dogs may experience side effects, such as soreness at the injection site or, rarely, an allergic reaction. Your veterinarian can help you weigh the pros and cons of immunotherapy for your dog and decide if it is the right option.

Exercise and Play


Caring for a dog with allergies may feel like an overwhelming task, but it’s entirely manageable with the right strategies in place. From understanding the root causes of allergies to knowing what treatment options are available, each element contributes to a comprehensive approach to your dog’s well-being. 

It’s essential to stay in close consultation with your veterinarian for diagnosis, treatment plans, and regular check-ups. 

Your commitment to understanding and addressing your dog’s allergies can make a significant difference in the quality of their life. After all, a comfortable and happy dog is the ultimate goal for any pet owner.
