Animal allergies occur when a person's immune system reacts to proteins found in the skin cells, urine, or saliva of animals. Common allergens come from pets like cats and dogs, but other animals, such as horses and rabbits, can also trigger allergic reactions. Symptoms may include sneezing, itching, and difficulty breathing. Diagnosis typically involves a physical examination and allergy testing, which can help identify specific triggers. Treatment options include avoiding contact with the animal, using antihistamines, or receiving allergy shots. Managing an animal allergy often requires a combination of strategies to reduce exposure and alleviate symptoms.
