Definition: Animal Dander

Animal Dander

All warm-blooded animals shed tiny flakes from their skin called dander. (It's like dandruff in humans but much harder to see.) It's this dander — along with proteins from saliva and other fluids that may be on an animal's skin — that causes allergies in humans.
