My DD8 has daily Zyrtec and Nasonex to control allergies with the option for nebulizer, Singulair and spacer+puffer as needed. Attacks are now rare and generally preceded by another upper respiratory illness or severe allergies. Getting rid of carpet was helpful. The dogs don't bother her. Going to homes with indoor cats is a problem. She does seem to be outgrowing it as she gets older. Ditto what everyone else said about getting flu shots and hand washing. Asthma specific checkups every 6 months with our pediatrician have been helpful for adjusting medications as needed over the years.
