While most of us know that people can be allergic to animal fur or feathers, fewer people know that pets can be allergic to human dander. In fact, people can be allergic to other people too, specifically the skin cells and hair found in dust. Pet allergies to human dander are actually not so rare, and there are a number of veterinary facilities that run allergy panel tests on pets. A pet's allergic reaction to human dander, which can take months or years to develop, usually results in extreme itching, rather than the respiratory problems that human allergies often manifest as.
