Collapsing trachea update

Paris has been having more trouble with his coughing lately. It has almost been a year since he was diagnosed with collapsing trachea and over a year since he started coughing.
Just this week I have had to increase his cough medicine to twice a day. I was home because of the holidays and I noticed him coughing much more, poor thing.
Thankfully the medicine does help, and I don't have to go to something stronger yet.
He just keeps on smiling and playing and being Paris.
