While some people have extreme reactions to allergens such as dog hair, usually it is more subtle, with the allergen causing an immune response in the affected people, with symptoms arising such as sneezing, itchy or swollen eyes, a runny nose, and puffiness in the face among other things.
It is a protein found in dog saliva that is the cause of many allergic reactions, though dander (dead skin particles) can also be a cause. As different dog breeds shed varying amounts of hair and dander, they will be more or less problematic for people with allergies./p>
People with other kinds of pets such as cats, rabbits, or guinea pigs may also experience issues with allergies. Whenever a pet sheds hair and dander, there is the possibility of triggering an allergic reaction in people susceptible to this immune response.
However, the more time your pet spends outdoors, the less contact you will have with their shed hair and skin. Therefore, the less of an allergic response you will have.
