Possibly. At least a third of people with asthma have pet allergies, which can make it difficult to manage asthma. If you’re not sure whether your daughter has allergies, her pediatrician may recommend seeing an allergist for testing. If she is allergic, the best way to stop symptoms is to remove the dog from the home. If that’s too emotionally difficult, talk to her doctor about managing symptoms with allergy medications and air purifiers and getting rid of upholstered furniture and carpeting. If you have to get rid of your dog, make sure your child knows it’s not her fault.
