teeter-
So sorry to hear about your baby. Our sheltie Elie was diagnosed 1 week ago and we are on Piroxicam 3mg/day. We are doing Pepcid 10mg/day to keep her tummy settled and no problems. In fact, good results so far.
We've used Sucrulfate and with good results. It's safe and effective for any upset GI problems. Best way to use it is to crush the pill and mix with a few tsp of plain yogurt. We'll go to sucrulfate if the pepcid isn't helping later.
I hate to give out advise on the diet since we're new to this too. We are switching to the EVO food from Nutura pretty much based from what I've found on the internet about grains and sugars feeding the tcc cells. I have no vet support to back that up. Our vet(s) say give it a try. Some people say home cooked meals are better than anything, but I think this is close.
Help that helps in some way,
Jeff
