How can you tell the difference between mild and not mild. Does it go by how much the trachea is collapses on the test or how often they have the symptoms? My dog makes a hack noise at least a few times a day since I got him at 4 months and he is now 1. Not a full blown cough just like the chi does in the video. Should he be treated?
