What does she eat? Im sure they told you she needed a no fat diet. My Charlie has pancreatitis he has had many of the symptoms that your baby has. He was dx almost 3 yrs ago they did something called a "snap test" in the office He was changed to a boiled chicken and rice diet and 1/2 a pepcid AC daily. I know that there are dog foods that are made for pancreatic issues but Charlie being the spoiled boy that he is wouldn't eat them. I had to take away allot of his treats due to fat content.
2 months ago he was also dx with a MVD, now this means NO protein LOL so what does he eat... we have changed him to Royal Canine hepatic its an all veggie diet he likes it thank goodness but it also meant new meds and they changed him to prilosec 5mg daily (good thing I work in a GI office

)
I know that dairy should be avoided as well. Im sure you know all this but I wanted to throw it out there just in case. wishing you well.
