Pet allergies occur when a person's immune system reacts to proteins found in a pet's skin cells, urine, or saliva. Common pets that can trigger allergies include cats and dogs. Symptoms may include sneezing, itchy eyes, and skin rashes, making it uncomfortable for those affected. To manage pet allergies, individuals can take several steps. Regular cleaning, using air purifiers, and keeping pets out of certain areas can help reduce allergens in the home. In some cases, allergy medications or immunotherapy may be recommended by a doctor to alleviate symptoms and improve quality of life.
