I am allergic to dogs too! I also have asthma, but not chronic. I have had immunotherapy for dog allergies as well, Sue. But I still have to take 1 pill a day to control it. I thought I would never do it, but Andrew wanted a dog so badly and I love him so much that I broke down and got the medicine! Almost two years, I could never imagine my life without the Drakester. He has been worth every penny and pill!
