Spanky has been reverse sneezing a lot and my other dogs (who have never done this before) are doing the same thing. They aren't coughing, so I don't know if it's kennel cough, but Spanky has a snotty nose and keeps doing the reverse sneezing thing. I have been giving him Robitussin, which seems to help, and he just had a Bordatella vaccine a few months before the show, but if anyone else is having the same problem, please let me know how you are treating them.
