I give mine only fresh blueberries for treats. Probably about 8 a day at different times. Pao was at the ER for a few nights so I am careful of what to give him. He does get about 20-24 grams in total per day of boneless skinless steamed/boiled chicken breast with his meals. As Dot mentioned, Cloud Star is okay but my dog would want the whole bag at once so I just stick to fresh blueberries for now.
I feed mine RC gastro low fat canned. I do give him a few pieces of the RC low fat gastro kibbles per day. Just be careful with the dry version as it is contains a lot of sodium. I know because I tried it

after a petsupply store owner told me about it and I find it hard to believe so I tried it and he was right. It is quite salty. The wet is fine.
With post pancreatitis dog, low fat, low fiber and moderate protein diet suits them the most.
