Here is something someone posted. It may be interesting to look into???

Delta, when Sooner had pancreatitis the vet initially put her on science diet id then put her on royal canine duck prescription. Hated both. But PLEASE have her make sure of diagnosis. Sooner did NOT have pancreatistis even though her numbers were off the chart. After 2 months of treating her for this she was finally diagnosed with lymphoma of the gi tract. This was after she developed lumps and they were biopsied. Further testing indicated lymphoma in 2 major organs, gi tract and skin. Do not always trust the vet, get second opinions please
