I'm not trying to hijack the thread well not much, anyway, but Lonecat (and any other vets) could I ask you a question?
My cocker spaniel has an absurdly sensitive stomach; she had acute panreatitis about four years ago (she's six now) and although she hasn't had any serious flare-ups since, she does very regularly get diarrhoea, and occasional vomiting. She is allergic/sensitive to wheat - any ingestion of that will give her the terrible squits and a flare up necessitating anti-inflammatory meds - and we feed her the blandest possible diet of Nature's Harvest chicken mixed with James Wellbeloved fish dried food (we've just switched to Fishmongers' Choice salmon dried food, as no grains at all). None of this is helped by the fact that she's a thieving little oik and will scavenge anything she can get her jaws around. 
We would love to feed her raw, and used to give her raw bones and chicken wings early on, but this always gave her the squits so we stopped. I've recently been looking at 'Honey's Real Dog Food', which is a raw food containing ground up raw bones etc..
My question is, would this be likely to trigger her pancreatitis, or would she be likely to adjust to it and benefit from the grain/filler free diet? I don't want to trigger an episode, but I would so much rather feed her ethically reared (the Honey's one is free range) food that isn't bulked out with cheap fillers like grain, or sugar beet pulp as the 'grain-free' alternative.
God I think I have hijacked, sorry.
I should probably start a thread with this myself, shouldn't I...
