Complications
Sinus infections
Ongoing (chronic) inflammation of tissues in the nasal passages caused by pet allergy can obstruct the hollow cavities connected to your nasal passages (sinuses). These obstructions may make you more likely to develop bacterial infections of the sinuses, such as sinusitis.
Asthma
People with asthma and pet allergy often have difficulty managing asthma symptoms. They may be at risk of asthma attacks that require immediate medical treatment or emergency care.
