Hidden trigger

My husband has asthma, and it really hasn't been bad for a very long time I thought it was the new dog that was putting him over the edge, and causing his troubles, but it looks like it was my pillows, I bought these 2-3 weeks before Moe came home , voila, I looked they were not down but their more allergic counterpart feathers, oops, no wonder and with four of them in this little area every time he has been home he has had trouble, so I packed the inserts up , and I can find polyester fill ones. Problem solved.
