Background/Purpose

Dander is the material shed by the Dog into the environment through hair and "dandruff". Dander is the "end product" and by far the most common source of Dog allergens and contains the highest proportion of dog specific allergens. It has naturally figured very prominently in clinical research, but all three allergen sources are important for an understanding of Dog allergy. Dog dander clearly represents an important source of inhalant allergens, and many studies report that Dog may frequently induce symptoms in sensitised individual. Symptoms include asthma, allergic rhinitis and allergic conjunctivitis. The dominant allergen in dog epithelium (e2). Dog dander (e5), however, contains several allergens such as albumin and other serum proteins, and is thus a more sensitive test.
