Checking with your vet is always the best. However, the first thing I thought of was reverse sneezing too. Ours has done that most of her life, and she is seven now. She does it more often when she pulls hard on her leash, and we try to always use a harness when we go for walks. She gets excited and does it occasionally, and sometimes she will just do it during the night. It doesn't seem to bother her after it is over. It is the strangest sort of cough or snort I have ever heard and can really scare you the first few times.
