Oh so sorry to hear about your baby Huricane. Izzy was just diagnosed with Pancreatitis this past November. I'm at work so I don't have her numbers when she was admitted. She was in the hospital for 2.5 days and has been symptom free since then..knock on wood.
She is on a low-fat, low-protein diet with no doggie treats except for some Cheerios now and then. For now she is on that nutty Science Diet ID (was on WD for two months to get her tummy settled down).
Izzy was on the best food ever and she still got it so don't beat yourself up. I would going forward not give him any table food that is loaded with fat or very high protein.
Keep us posted on his progress.
