Types of Pets

Some pets are more likely to trigger asthma symptoms than others. While there is no completely hypoallergenic pet, certain species or breeds may produce fewer allergens or be less likely to cause asthma symptoms. It is crucial to consider individual sensitivities and consult with a healthcare provider before bringing a pet into the home.

Pet Allergens

Common pet allergens include pet dander, which consists of tiny flakes of skin shed by animals, as well as saliva and urine. These allergens can trigger an allergic reaction in individuals with asthma, leading to symptoms such as coughing, wheezing, and difficulty breathing. Minimizing exposure to these allergens is essential for managing asthma symptoms effectively.

Allergens from Pets

Understanding the specific allergens associated with pets can help individuals manage their asthma symptoms and make informed decisions regarding pet ownership.

Pet Dander

Pet dander refers to the tiny particles of dead skin shed by pets, and it is a common allergen that can trigger asthma symptoms. Even if a pet does not shed much hair, dander can still be a concern. It can become airborne and easily spread throughout the house, making it crucial to take steps to reduce exposure to dander.


Pet saliva can also contain allergenic proteins that can trigger asthma symptoms in sensitive individuals. When pets groom themselves, their saliva can dry on their fur and become airborne, potentially causing an allergic reaction. Avoiding close contact with areas contaminated with saliva can help minimize exposure.


Pet urine can also contain allergenic proteins that can trigger asthma symptoms. In homes with pets, urine can end up on various surfaces, including carpets and furniture, making it important to clean and sanitize these areas regularly to reduce exposure to allergens.

Differences between Pet Allergies and Asthma

Although pet allergies and asthma can have similar symptoms, it is essential to understand the differences between the two to ensure proper diagnosis and treatment.

Pet allergies are caused by a specific reaction to allergens produced by animals, such as pet dander, saliva, or urine. On the other hand, asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways. While pet allergens can trigger asthma symptoms in some individuals, asthma itself is not solely caused by pet allergens.


Both pet allergies and asthma can cause symptoms such as wheezing, coughing, and shortness of breath. However, pet allergies typically present with symptoms such as sneezing, runny nose, itchy eyes, and skin rashes, in addition to respiratory symptoms. Asthma symptoms are primarily focused on the respiratory system, including difficulty breathing and chest tightness.


The treatment approaches for pet allergies and asthma differ. Pet allergies can be managed by avoiding exposure to pet allergens, taking over-the-counter antihistamines, or using prescribed medications. Asthma requires a more comprehensive treatment plan, including medication to manage inflammation and bronchodilation, as well as avoidance of triggers. It is crucial to consult with a healthcare provider for a proper diagnosis and personalized treatment plan.

Minimizing Exposure to Pet Allergens

If you or someone in your household has asthma, taking steps to minimize exposure to pet allergens can significantly improve symptoms and overall lung function.

Creating Pet-free Zones

Designating specific areas of the house as “pet-free zones” can help reduce allergen exposure. Keep pets out of bedrooms and other areas where individuals with asthma spend significant time. This can provide a safe space where individuals can find relief from their symptoms.

Regular Cleaning

Regular cleaning of the house is crucial to reduce pet allergens. Vacuuming carpets and upholstery frequently, dusting surfaces, and washing bedding in hot water can help remove allergens from the environment. Choosing cleaning products that are labeled as “asthma-friendly” can also minimize exposure to irritants and chemicals.

Air Filtration

Using high-efficiency particulate air (HEPA) filters or air purifiers can help remove pet allergens from the air. These devices are effective at trapping microscopic particles, including pet dander, and can greatly improve indoor air quality. It is important to regularly clean or replace the filters to maintain their effectiveness.

Choosing Pet Breeds for Asthma Sufferers

While no pet breed is completely hypoallergenic, certain breeds may produce fewer allergens, making them a better choice for individuals with asthma. Consider the following factors when choosing a pet breed:

Hypoallergenic Breeds

Some breeds are known to produce fewer allergens or have hair instead of fur, which can help minimize allergic reactions. Examples of hypoallergenic breeds include poodles, bichon frises, and sphynx cats. It is essential to spend time with the specific breed to assess personal sensitivities before bringing them home.

Low-shedding Breeds

Pets that shed less hair or have shorter hair may produce fewer allergens. Breeds such as Yorkshire terriers, shih tzus, and Devon Rex cats are known to shed less and may be more suitable for individuals with asthma. Regular grooming and bathing of pets can also help reduce allergen exposure.
