26% of European adults coming to the clinic for suspected allergy to inhalant allergens are sensitised to cats and 27% to dogs (Consensus document on dog and cat allergy http://bit.ly/2qYqzMQ).Dust samples were collected from the floor of infants' bedrooms and processed for the main dog allergen Canis familiaris 1 (Can f 1). The characterization of the dog was based on coat type, dander level, and shedding.
The number of dogs in the home was not related to dog allergen levels. Homes with exclusively outdoor dogs had lower levels of dog allergen than homes with indoor dogs. Homes where the dog was allowed in the infant's bedroom had significantly higher Can f 1 levels on the child's bedroom floor.
Dogs in the home corresponded to dog allergen in the home. No dog characteristic, other than altered status, was associated with allergen levels in the home.
