What is your question?
Awaiting your reply.
I have a couple of questions for you:
Are there any other pets in the household?
There are various causes for enteritis or swollen intestines. The cause could be one of the following - inflammatory bowel disease, bacterial or viral infection, food allergy, or lymphoma (a type of cancer).
When your vet does the endoscopy (camera) they should be able to take a biopsy and see exactly what the cause is and give you a prognosis.
It's good that she is on a prescription diet for her condition.
Is she a nervous dog? Another cause for her signs could be stomach ulcers.
The endoscopy will be very valuable in determining the underlying cause. Hopefully, it will be due to inflammatory bowel disease which is manageable.
What did the endoscopy reveal? How is Moli doing?
