what i have found..... is that these things pretty much sound the same!!!!......... my toby had kennel cough (and we let it run its course because it was not serious and he didnt have a secondary infection) and we took him to a friend of mine that knows yorkies through and through and at first the diagnosis was kennel cough, then reverse sneeze, then possibly collapsing trachea, and then back to kennel cough again........ if you look up the definition and the symptoms on all these things, they all describe the same thing (someting caought in the throat, honking, ect....) scared the hell out of me...........toby started out doing it periodically then it got progressivly worse, then he stopped doign it competely ...... now hes done it once or twice in the past three days (i took him on a walk when it was raining
........ i know i know... bad me...... but he had fun and we dried him off really good and made him a nice warm spot by the fireplace)
