Being an animal lover myself, especially dogs, I'm so sorry to read about your allergic reaction. For what it's worth, years ago my grandmother had this problem and lived with my parents who had a little dog. There was some kind of a lotion kind of stuff they put on the dog to keep the dander down so she was able to tolerate it with no allergic reactions. Maybe somebody else has heard of such a thing......perhaps your pcp might know....before you take him back. Just a thought. Good luck!

Hugs.......
