What are dog allergies?

Definition of dog allergies

Dog allergies are a common health condition among humans that are caused by an allergic reaction to certain substances found in dogs. These substances, known as allergens, can be found in a dog’s dander, saliva, urine, fleas and ticks, mold and pollen, food ingredients, and even cleaning products. When exposed to these allergens, some individuals may experience a range of symptoms that can vary from mild to severe.

Common symptoms of dog allergies

The symptoms of dog allergies can manifest themselves in different ways, depending on the individual. Some common symptoms include sneezing, nasal congestion, runny or itchy nose, watery or itchy eyes, coughing, wheezing, shortness of breath, skin rashes, hives, itching, and even gastrointestinal issues. These symptoms can significantly impact the quality of life for allergic individuals, as they can be persistent and interfere with daily activities.

Causes of dog allergies

Dog allergies are caused by an overreaction of the immune system to specific proteins found in a dog’s dander, saliva, and urine. When a sensitive individual comes into contact with these allergens, their immune system releases chemicals, such as histamine, that trigger the allergic response. Although the exact cause of dog allergies is not fully understood, it is believed to be a combination of genetic and environmental factors.

Different types of dog allergies

There are different types of dog allergies that individuals can experience. The most common type is allergic rhinitis, which affects the nasal passages and causes symptoms such as sneezing and nasal congestion. Another type is allergic dermatitis, which results in skin reactions such as rashes and itching. Some individuals may also develop asthma-like symptoms, known as allergic asthma, when exposed to dog allergens. It is important to identify the specific type of dog allergy to determine the most effective treatment approach.

Identifying dog allergies

Methods for identifying dog allergies

Identifying dog allergies can be challenging, as the symptoms can be similar to those caused by other allergens or respiratory conditions. However, there are several methods that can be used to determine if a person is allergic to dogs. These methods include skin allergy tests, blood allergy tests, elimination diets, and keeping a symptom diary.

Skin allergy tests

Skin allergy tests, also known as patch tests or prick tests, are commonly used to identify specific allergens that trigger allergic reactions. During the test, small amounts of various dog allergens are applied to the skin and then gently pricked or scratched. If a person is allergic to any of the tested allergens, a small raised bump, known as a wheal, will appear at the site of the test.

Blood allergy tests

Blood allergy tests, or specific IgE tests, can also be used to identify dog allergies. These tests measure the levels of specific antibodies, called immunoglobulin E (IgE), in the blood. Elevated levels of IgE antibodies to dog allergens indicate an allergic reaction. Blood tests can provide a broader assessment of allergies and may be useful in cases where skin tests are inconclusive or if the person cannot undergo skin testing.

Elimination diet

An elimination diet involves systematically removing potential allergenic foods from the diet for a period of time and then reintroducing them one by one to identify any adverse reactions. This approach can also be used to determine if specific food ingredients are causing allergies in individuals who suspect a food allergy is contributing to their dog allergy symptoms.

Keeping a symptom diary

Keeping a symptom diary can help identify patterns between exposure to dogs and the onset of allergy symptoms. Individuals can record their symptoms, the duration of exposure to dogs, and any other potential triggers. This diary can provide valuable information to healthcare professionals when assessing the extent and impact of dog allergies.

Common dog allergens


Dander refers to the dead skin cells that dogs shed regularly. It is one of the most common allergens associated with dogs and can become airborne, making it easy for sensitive individuals to come into contact with it. These tiny particles can trigger allergic reactions in some people, leading to symptoms such as sneezing, itching, and respiratory distress.


While it may seem surprising, dog saliva can also trigger allergic reactions in susceptible individuals. When dogs groom themselves or lick their fur, the saliva can deposit allergens onto their fur, which can then be transferred to surfaces and cause allergic symptoms when an allergic person comes into contact with these surfaces.


Dog urine contains proteins and other substances that can cause allergic reactions in some individuals. When a person with a dog allergy comes into contact with surfaces contaminated with dog urine, such as carpets or furniture, they may experience symptoms such as skin rashes or respiratory issues.

Fleas and ticks

Fleas and ticks are common parasites that can infest dogs. In addition to causing discomfort and health issues in dogs, their presence can also trigger allergic reactions in humans. The saliva of fleas and ticks contains allergenic proteins, and when a dog is infested, these allergens can be spread throughout the environment, leading to allergic symptoms in sensitive individuals.

Mold and pollen

Mold and pollen are environmental allergens that can be brought into the home on a dog’s fur or carried through open windows and doors. These allergens can then trigger allergic reactions in individuals who are sensitive to them. Mold and pollen can cause symptoms such as sneezing, congestion, and itchy eyes in allergic individuals.

Food ingredients

Some dogs may develop food allergies or intolerances to certain ingredients in their diet. When individuals come into contact with these allergenic food ingredients, either through direct contact or via saliva or dander, they can experience allergic symptoms. Common food allergens for dogs include beef, chicken, dairy, grains, and certain additives or preservatives.

Cleaning products

Many cleaning products, such as detergents, disinfectants, and air fresheners, contain chemicals that can trigger allergic reactions in humans. When these products are used to clean surfaces or fabrics that dogs come into contact with, the allergens from these products can be transferred onto the dog’s fur and then spread throughout the environment, posing a risk to allergic individuals.

Preventing dog allergies

Creating an allergy-free home environment

To prevent dog allergies, it is important to create an allergy-free home environment. This can be achieved by designating certain areas of the home as dog-free zones, such as bedrooms or living areas with carpeting. Using hypoallergenic bedding and furniture covers can also help reduce allergen exposure.

Frequent cleaning and air purifiers

Maintaining a clean living environment is crucial for reducing allergen exposure. Regular vacuuming with a high-efficiency particulate air (HEPA) filter vacuum cleaner can help remove allergens from carpets and upholstery. Using air purifiers with HEPA filters can also help minimize airborne allergens, providing relief for those with dog allergies.

Regular grooming of the dog

Regular grooming of the dog is essential in managing dog allergies. This includes bathing the dog regularly with hypoallergenic shampoos and brushing their fur to remove dander and potential allergens. It is also important to keep the dog’s living areas clean and free of dust and allergens.

Limiting exposure to allergens

Limiting exposure to dog allergens is key in preventing allergy symptoms. This can be achieved by avoiding direct contact with dogs, especially if they are known allergenic breeds or shedding excessively. Washing hands after touching dogs, avoiding close contact with dog bedding or toys, and removing shoes before entering the home can also help reduce allergen exposure.

Treating dog allergies

Medications for dog allergies

Medications can be used to manage and alleviate the symptoms of dog allergies. The most common medications for dog allergies are antihistamines, corticosteroids, immunotherapy, topical treatments, and alternative treatments.


Antihistamines are commonly used to relieve allergy symptoms, such as sneezing, runny nose, and itching. These medications work by blocking the release of histamine, a chemical that triggers allergic reactions. Antihistamines are available over the counter or as prescription medications, and the selection of the appropriate antihistamine depends on the individual’s symptoms and medical history.


Corticosteroids, commonly known as steroids, can be used to reduce inflammation and suppress the immune response in severe cases of dog allergies. They can be administered orally, topically, or via injections. Corticosteroids are effective in relieving symptoms; however, long-term use requires careful monitoring due to potential side effects.


Immunotherapy, also known as allergy shots, is a long-term treatment option for dog allergies. It involves introducing small amounts of dog allergens into the body to desensitize the immune system gradually. Over time, this can reduce the severity of allergic reactions and minimize the need for medication. Immunotherapy is typically administered by an allergist and requires regular visits over a period of several months to years.

Topical treatments

Topical treatments such as creams or ointments can be used to manage allergic skin reactions caused by dog allergies. These treatments aim to soothe and relieve itching, redness, and inflammation. Corticosteroid creams or ointments may be prescribed for more severe skin reactions.

Alternative treatments

Some individuals may opt for alternative treatments for dog allergies, such as herbal remedies, acupuncture, or homeopathy. It is important to note that the effectiveness of these treatments varies, and it is recommended to consult with a healthcare professional before trying alternative therapies.
