Understanding Environmental Allergies in Dogs

Environmental allergies in dogs are different from food allergies and are caused by common allergens found in the environment that can trigger allergic reactions.

Difference Between Food Allergies and Environmental Allergies

Food allergies and environmental allergies in dogs comprise two different mechanisms, yet both elicit tangible discomfort. In a nutshell, food allergies occur when a dog’s immune system reacts adversely to specific ingredients present in their diet.

For instance, common culprits include dairy products, wheat, and certain types of meat. The symptoms often manifest as gastrointestinal issues like vomiting, diarrhea or bloating.

On the contrary, environmental allergies are triggered by substances your pooch encounters in its surroundings rather than what they eat. Common allergens could be pollen from trees or grasses, mold spores or dust mites.

The immune system mistakenly identifies these harmless substances as threats and overreacts, producing immunoglobulin E (IgE) antibodies that attach to mast cells found in connective tissues, triggering the release of histamines that result in itching and inflammation seen on the skin.

Common Allergens in the Environment for Dogs

Pollen, dust, mold, and grass are the top perpetrators in stimulating allergic reactions in dogs. These environmental elements often sneak into homes unnoticed, triggering allergies to your furry friend.

As pet owners become more conscious of their dog’s health, they should be aware that these allergens could be causing itchy episodes or irritated skin.

Seasonal changes also bring about different types of pollen, which dogs may inhale or come into contact with on walks or outings to parks.

Signs and Symptoms of Environmental Allergies in Dogs

Environmental allergies in dogs can manifest through signs such as excessive scratching and itching, persistent licking of paws, and face rubbing.

Scratching and Itching

Environmental allergies in dogs often manifest through persistent scratching and itching. This is typically driven by the body’s release of histamines, which can cause various reactions, including redness, inflammation, sneezing, and skin irritation.

While scratching is a natural response to itchiness for dogs, chronic scratching can lead to more serious problems, such as sores and infections. Environmental allergens include common substances like dust mites or pollen, which can trigger this excessive itching behavior.

Licking, Especially the Paws

Dogs with environmental allergies often exhibit signs of discomfort, and one common symptom is excessive licking, particularly of the paws. This behavior can indicate itching and irritation caused by allergens in the environment.

When allergens enter a dog’s body, mast cells release histamines, leading to inflammation and triggering scratching or chewing behaviors. Licking the paws is a way for dogs to alleviate their discomfort, but it can also lead to further irritation and create a cycle of itching and licking.

Face Rubbing

Face rubbing is a common sign of environmental allergies in dogs. When dogs are allergic to certain environmental substances, such as pollen or dust mites, it can cause itching and irritation.

This discomfort often leads to excessive scratching and licking, including rubbing their face against furniture or the floor. The allergens trigger mast cells in the dog’s body to release histamines, which then result in redness, inflammation, and itchiness.

Diagnosing Environmental Allergies in Dogs

Various allergy testing options are available for dogs, and it is important to work with a veterinarian to determine the best approach for diagnosis.

Allergy Testing Options

Allergy testing options are crucial for diagnosing environmental allergies in dogs. Understanding the specific allergens that trigger your dog’s symptoms is essential for effective treatment and management.

Blood tests, like the immunoglobulin E (IgE) antibody test, measure the levels of antibodies in your dog’s blood that react to certain allergens. This type of test can provide a comprehensive analysis of potential allergens, helping you identify what triggers your dog’s allergic reactions.

Working with a Veterinarian for Diagnosis

Your veterinarian is a crucial partner in diagnosing and managing environmental allergies in dogs. To accurately diagnose your dog’s allergies, the vet will conduct thorough testing, such as skin or blood tests, to identify specific allergens triggering your dog’s symptoms.

By considering all these factors, the veterinarian can provide an accurate diagnosis and tailor a treatment plan to suit your furry friend’s needs. Remember that each dog is unique, so it’s important to have professional guidance from a veterinarian when dealing with environmental allergies.

Treating Environmental Allergies in Dogs

Treating environmental allergies in dogs involves avoiding allergens, administering medications for symptom relief, and considering immunotherapy options.

Avoiding Allergens

To help manage environmental allergies in dogs, it’s important to take steps to avoid allergens. One way is by keeping your dog’s living environment clean and allergen-free. Regular cleaning and vacuuming can help remove dust, pollen, and other irritants from your home.

Additionally, using hypoallergenic bedding for your furry friend can prevent exposure to potential allergens.

Another way to avoid allergens is by paying attention to the outdoor environment. During peak allergy seasons, such as spring when pollen counts are high, try limiting your dog’s time outside during those times of day when pollen levels are at their highest.

Medications for Symptom Relief

Treatment options for environmental allergies in dogs often include medications that provide symptom relief. These medications can help alleviate itching and other allergy symptoms, improving the dog’s overall comfort.

Some commonly prescribed medications for dog allergies are steroids, such as prednisone, anti-allergy drugs like Atopica or Apoquel, and injectable drugs like Cytopoint.

Immunotherapy Options

Immunotherapy options are available for treating environmental allergies in dogs. These options aim to induce tolerance to allergens and reduce sensitivity. Immunotherapy can be used alongside other medications to help reduce itching in dogs with atopic dermatitis, a common allergic skin condition.

In some cases, blood protein supplements rich in immunoglobulins may also be beneficial for reducing inflammation and promoting healing. It’s important to note that managing atopic dermatitis may require a combination of therapies tailored to the individual dog’s response, so consulting with a veterinarian is crucial for determining the best course of action.

Natural Remedies for Environmental Allergies in Dogs

Discover effective and natural ways to alleviate your dog’s environmental allergies, from bovine colostrum to omega-3 fatty acids. Read on for more information!

Bovine Colostrum

Bovine colostrum is a natural remedy that can help dogs with environmental allergies. It contains antibodies that boost the immune system, helping dogs fight off allergens more effectively.

Using bovine colostrum as a supplement can relieve dogs suffering from environmental allergies. By boosting their immunity, it helps reduce their symptoms and discomfort.

Apple Cider Vinegar

Apple cider vinegar is a natural remedy that can relieve dogs suffering from environmental allergies. It has properties that help to reduce itching caused by allergens and can even assist in removing these irritants from your dog’s skin.

This can help soothe itchiness and remove any allergens that may be lingering on the feet. Additionally, you can create a spray by diluting apple cider vinegar with water and applying it directly onto your dog’s coat or affected areas to alleviate itching and provide some much-needed relief.

Bee Pollen

Bee pollen is a natural remedy that can help manage environmental allergies in dogs. It works by desensitizing your dog to the specific pollen they are allergic to, helping to reduce symptoms such as itching and scratching.

Using bee pollen as part of your dog’s allergy management plan has many benefits. Not only does it provide symptom relief, but it also supports their overall immune system health. Bee pollen is packed with vitamins, minerals, and antioxidants, making it a nutritious supplement for your furry friend.


Herbs are a natural and holistic approach to managing environmental allergies in dogs. Some herbs have immune-boosting properties that can help strengthen your dog’s defenses against allergens.

These herbs reduce the release of histamines, which cause allergic reactions in the body. Another effective option for allergy relief is omega-3 fatty acids, which regulate the inflammatory response associated with allergies in dogs.

Omega-3 Fatty Acids

Omega-3 fatty acids regulate the inflammatory response that causes dog allergies. These essential fats can be found in cold-water oily fish like mackerel and sardines, making them a great natural source of omega-3s for your furry friend.

If your dog doesn’t enjoy fish, you can also consider giving them supplements such as green-lipped mussel oil or ahiflower oil – both excellent sources of omega-3 fatty acids. Incorporating omega-3s into your dog’s diet can help support their immune system and manage their environmental allergies more effectively.


Quercetin, a bioflavonoid, is a natural remedy for environmental allergies in dogs. It contains compounds that act as antihistamines, helping to reduce inflammation, redness, and irritation caused by allergies.

You can find quercetin in certain fruits and vegetables like apples, berries, and onions. Alternatively, it can also be taken as a supplement. By acting as an antihistamine, quercetin helps to stop the release of histamines in the body and relieves allergy symptoms in dogs.

Preventing Environmental Allergies in Dogs

Regular grooming and bathing, keeping the environment clean and allergen-free, and managing flea infestations are all crucial steps in preventing environmental allergies in dogs.

Regular Grooming and Bathing

Regular grooming and bathing play a crucial role in preventing environmental allergies in dogs. Keeping your dog’s coat clean can effectively remove allergens such as pet dander, pollen, dust mites, and mold spores that may trigger an allergic reaction.

When your dog is exposed to these allergens, mast cells in their connective tissues release histamines, which cause itching and discomfort. However, regular bathing helps to eliminate these irritants from the coat and reduces the release of histamines.

Keeping the Environment Clean and Allergen-Free

To prevent environmental allergies in dogs, keeping their environment clean and free of allergens is crucial. Regular cleaning of the house will help reduce the presence of dust mites, pet dander, and other common allergens that can trigger allergic reactions in dogs.

Vacuuming carpets, washing bedding with hypoallergenic detergent, and using air purifiers can significantly reduce the allergen load inside the home. Keeping outdoor areas well-maintained can minimize exposure to pollen and other allergens.

Managing Flea Infestations

Flea infestations can be a major concern for dogs with environmental allergies. Flea saliva contains allergenic proteins that can trigger allergic reactions in dogs, worsening their symptoms.

Another key aspect of managing flea infestations involves keeping your home environment clean and free from allergens. Vacuuming regularly helps eliminate fleas and removes any trapped allergens like pollen or dust mites from carpets and furniture.

When to Consult a Veterinarian

If your dog is experiencing severe or persistent symptoms, if symptom management has been ineffective, or if you have any concerns or questions about your dog’s environmental allergies, it is important to consult a veterinarian.

Severe or Persistent Symptoms

Severe or persistent symptoms of environmental allergies in dogs can cause a lot of discomfort for your furry friend. These symptoms include intense itching and scratching, hives or raised bumps on the skin, ear infections, hair loss, constant chewing or licking of paws, frequent sneezing, and watery eyes.

Taking these symptoms seriously is important as they can indicate an allergic reaction that needs attention.

Ineffective Symptom Management

If your dog’s allergy symptoms are not improving despite treatment, it may indicate ineffective symptom management. Steroids and anti-allergy drugs are commonly used for treating environmental allergies in dogs, but they can have side effects or suppress the immune system.

Over-the-counter allergy drugs may provide temporary relief but do not address the underlying cause. It is important to consult with your veterinarian if you notice that your dog’s symptoms are not getting better or if they worsen over time.

Any Concerns or Questions

If you have any concerns or questions about your dog’s allergies, it’s important to consult a veterinarian. Severe or persistent symptoms like constant itching, hair loss, or frequent ear infections may indicate your dog’s allergies are not effectively managed.


Environmental allergies in dogs can cause significant discomfort and health issues. As responsible dog owners, it is crucial to be aware of the signs and symptoms of these allergies and take appropriate measures to prevent and manage them.
