My 3yr old daschund just spent 5 days @ the vets form vomitting. The only thing they could find was that his pancreas was a little inflamed. I got him to eat 2-4 morsels of food and he I did get about half a dog biscuits down him last night and it has all stayed down. But this morning he won't eat any thing. He has been drinking though. Any suggestions? Any questions to ask the vet?
