It really doesn't matter what it is, as long as there is a constant load on the tissues, it will cause a problem over the long term.
This is based on my experience of working with dogs everyday with this problem. As I said, some young and some old.
It is not a natural state of breathing, when there is reversing sneezing or coughing; doesn't matter; this is an out of balance condition (an indication thereof).
Chinese medicine says that any chronic coughing (honk in this case) is "the escape of qi" (qi is energy)
That makes sense...because any chronic condition wears away at the natural resources of the body, weather it is a dog or a human.
