Its see-saw temps where I am right now. It was freezing a few days ago and today its 60 degrees. LOL I always wondered if he has hayfever TBH. I do saline spray whenever he sounds congested and it seems to help but only for a few hours and then he's back stuffy. Its worse at night and sometimes interferes with his sleep. I also use a humidifier at night and those vapor plug in things.....
BTW, his gas also seems worse at night and I do use gas drops but they really dont seem to help.
