YorkieDaze is right - you should keep some Wellness kibble in case you want it tested.
If ALL blood tests are 100% normal, why is the vet wanting to proceed as if it's pancreatitis? This part of the vet's decision doesn't make any sense to me.
I'm the worst fan of prescription foods, but if he was doing okay on it for those 2 days - I'd probably put him back on it, just to get him settled. See how he does for a few days. If he stays settled, it does make me wonder about that bag of food. If he stays settled over the next week, I'd probably then transition him off the food.
That said, I share EllieMay's (Crystal) concerns as to "what's going on here" - given the direction the vet is going here (kinda odd).
IF he gets sick again - I always give mashed potatoes (no protein right away, to hard to digest) - either canned or fresh with a bit of butter. You can also give a 1/2-1 tsp of Pepto Bismol. Canned pumpkin for diarrhea or if it's
really bad, Immodiam or Kaeopectate (1/2-1 tsp).
Keep us posted!
