My Chi Pin is coughing

[Bandittodd]

My Chi Pin has been having a cough like a cat coughing up a hairball we thought it was kennel cough but after 3 weeks of treatment that has been ruled out they are telling me he may have a Tracheal collapse where his air way gets blocked when he gets too excited or gets over heated it is something that is common for smaller breeds has anyone else had this problem
