[Kaos]

Kaos went to the vet for checkup/shots like 2 weeks ago. He has reverse sneezed like 5x throughout his whole life, so I know what it is. But since the appointment he does it at least 10x a day. The vet said he was in perfect health w/bloodwork and everything, but now I'm worried. He did get the kennel cough vaccine in his nose too that day. Should I be worried?? After reading all the sudden things that happen to these little guys, I tend to over react to every little thing.
