Are they sure Cooper is causing the cough? When I was having allergies and bad headaches, my doctor asked if I let my dog (Biscuit) on the bed. I said I did. Without any further testing or questions, he sent me away with "Don't let him get on the bed!" I wasn't satisfied with this... well, it turns out I'm actually allergic to mold, not Biscuit
I'm just sharing this because it's something to think about if your cough persists. I hope Cooper sleeps well tonight and your cough goes away
