What is pet dander?

Most people believe that that the airborne fur/hair of pets causes allergies but it is the airborne saliva and urine-derived proteins that cause allergies from pets. Glands in the skin of the pet also produce these allergies and pets shed the upper layers of their skin cells.29Dander is the name used for the microscopic particles of skin shed by pets and it is these tiny flecks of skin that can cause allergic reactions, as well as the proteins found in the saliva, urine and faeces.25 The fur may be coated with allergen proteins deposited from dried saliva when the pet licks its fur but the skin (dander) is the major source of the pet allergen.29

Pet dander can be found on clothing, bedding, upholstery, cars, rugs – in fact anywhere where the pet has been present and may have deposited dander or where the dander has stuck to clothing and the clothing has been present (for example on public transport, in the office or at school). It can remain in a home for up to six months or more after the pet has been remove.29
