The effect of dog allergen exposure on asthma morbidity among inner‐city children with asthma.

Dog-associated non-allergen exposures were derived from residual effect of dog presence in the main model for the association between dog allergen exposure and asthma morbidity. Asthma morbidity outcomes by dog allergen exposure and sensitization to dog allergen Further, the effects of animal-associated non-allergen exposure derived from the presence of other animals and exposures to allergens were tested and found not to be consistently associated with asthma morbidity, except for mouse allergen (Table S3). Even when exposure to other animal allergens was included in the model, dog allergen exposure remained significantly associated with respiratory outcomes, which suggests that dog allergen is an independent risk factor for asthma morbidity.
