As important as the breed of your furbaby is the other stuff you do to control your allergies. My DH has fought with severe breathing allergies all of his life. I have for a shorter period. Air filtration is very important. We have dust mite covers on our bedding. Our vacuum is a HEPA type. We wash the windowsills with a bleach solution several times a year (mold often grows there, as well as in bathrooms). Our allergist recommended both OTC and Rx allergy meds, as well as on-line sites for asthma/allergy products. DH washes his sinuses with a special device and saline solution (UGH!) this may be more than you wantd to hear, but the dog is not the only hazard.
