From my past experience Jen, Kennel Cough is a dog's version of the human cold. Being viral in nature it normally has to run it's course. However as with humans, the very young and old can have adverse affects of something that is normally simple for the body to handle, Pneumonia being the worse end of it.
Jayda, our oldest Italian Greyhound had it when we go her as a puppy. She came from a puppy store. Jayda was about 25% underweight, did not want to eat much. After a few weeks of the Vet trying this and that to treat her, I suggested putting her on Azithromycin, as my biggest concern was for it to go from an Upper Resp infection, to a lower Resp infection, which could have easily lead to Pneumonia. It seems the Azithromycin did the trick. We also had Jacki and a few other dogs here at that time, but none of them caught it.
If you are going to give anything on your own, just make sure it has NO Tylenol in it. Tylenol is Lethal to dogs.
This could also be seasonal allergies they are suffering from, it is that time of year for running noses, itch watery eyes and sneezing, and reverse coughing that dogs do, which could very well be confused for Kennel Cough.
Charlie, are you Hungry ?
