Well Jeepers!
After I read your post,I decided to google it,and this is what I found.
1-It could be an imbalance of bacteria in the intestines,just past the stomach
2-liver & kidneys enzymes should be checked,especially os if the dog has been on any type of NSAID
3-Most of what I read,the diagnosis was Inflamatory bowel syndrome,or some other type of gastric issue
4- parasites(but that has already been checked)
5- food allergy
6-dog is hungry
Remedies mostly included,some type of pepcid,or medicaction for irritable bowel,late night snacks. Change of diet temporarily to chicken,rice,lamb
There are gadzillions bits of info on the internet about the issue,but your vet should be the best source of information. One thing that does repeat itself in any thing I have read,is that it is treatable,and usually passes as the pup grows.
It just sounds to me that she is having a gastric problem,I would call your vet again,and arrange another visit,to discuss some things with him.
Here is a link that has lots of postings:
