Thank you all so much for the good wishes. The 4 vets at the office have conferred and are just baffled by this. He's had pancreatitis before, but this came on so suddenly and Woofie had a small bout of the same thing. We did find that Kirby seems to react badly to the Science Diet I/D food. The stuff they recommend for dogs with touchy tummies. Go figure.

He's currently taking metronidazole, prednisone and a nutritional supplement twice a day.

Keeping my fingers crossed. He's made it for the last 36 hours without vomiting. It seems to be one meal/one day at a time with him.
