Hello, I'm sorry to hear about your fellow Bobby and I'd like to help.

The problem with diets for patients with pancreatitis is that they tend to be fairly bland and thus many dogs don't enjoy them.

I am very glad to hear that his attitude and activity level have returned to normal, those are excellent signs.

And the fact that he ate with relish the biscuits meant for your other pup tells me his appetite is good, it may just not be good for things that don't have much taste.

Is he still losing weight? If not and he has stabilized, even if he's still not where he was before he was sick, then I am much less concerned.

Now it's a matter of getting him interested in eating what is good for him. You can try mixing in sweet potatoes, squash, oatmeal, mashed white potatoes, pumpkin, green beans, zucchini and carrots. Pasta and white rice are also fine but I see that you've tried these and he's been less than excited about them. These all add flavor and calories, but not fat, so are safe. You can also try feeding him a different prescription diet called Purina Veterinary Diets OM. This is a high fiber food that some dogs prefer the taste of compared to Hills i/d. Perhaps he is missing crunchies and if that's the case offer him dry i/d or Purina Veterinary Diets OM.

You can also take canned i/d dog food, smash it together in a tight ball, roll it out and cut out shapes and bake it at 225F to 250F for 10 to 15 minutes to make "dog biscuits".

Let me know if you have further questions.
