Dander is the primary airborne allergen trigger for humans allergic to pets, distinct from fur itself.
The story behind the word. Emerged in 16th-century English dialects, likely derived from Scandinavian roots meaning scurf or scaling skin. It became a crucial medical term in the 20th century as immunologists identified skin protein flakes as primary pet allergens.
