Sorry I don't have experience with this. But I know finding kidney friendly and pancreatitis friendly diets are often hard (often kidney diets are too high in fat).
Maybe talk to your vet about JustFoodForDogs. They have some RX diets that MAY be appropriate?

or if you could homecook, check out BalanceIT and consult a board certified nutritionist.
