My dog has kennel cough. Can I give meds early? Is mucus normal?

4 year old 40lb dog diagnosed with a bad cold/kennel cough. I was given dex/guaifenesin tabs with instructions of giving them 3x a day (as well as a course of doxy). Can I give the dex/guaf a few hours early to calm cough before bedtime? Also, dog has been coughing up mucus - is that because of the expectorant?

Expectorants aid in the clearance of mucus from the airways, so yes Wilco's coughing up mucus is due to that medication. I would not give the dex/guaf early, it's very important to take the drugs as the vet has prescribed.
