Two of my dogs have similar episodes that sound like gagging, and it happens when they get startled or over excited, although there are other causes. It is a minor spasm condition, and usually stops on it's own within less than a minute. Only a vet can tell you for sure. Here are some links to info about reverse sneezing, in case it is helpful.

good info, also he's likely never been in a car before he may have been stressing out or throwing up?
