Yes! Thank you to all for responding to my post as well. The environmental issues are a good one for me to research. We live in south Texas on a peninsula in the Gulf of Mexico, so humidity and high levels of mold are the norm. We've been gutting our house room-by-room over the last 13 years to repair and update it, so there have been a lot of new materials, construction dust, etc. And then our town took the direct hit from Hurricane Harvey, our home was flooded, and we're still not back in it. We've decided to abandon our coastal life and move inland, so those environmental factors will be changing. If our gal's health has been impacted by the home and location, maybe the move will make a difference. I hope it's not too late if that's the case.
