Turns out Tibbe had high bile acids even with all normal blood tests for liver function and a nuclear scintigraphy and abdominal sonogram ruled out polysystemic/liver shunt and his vets now say he probably has hepatic MVD(microvascular dysplasia) that was causing his tummy troubles. He was born with it and it's an inherited condition but often it doesn't show up until a dog is beyond puppyhood. A special diet has now stopped his tummy troubles and he's back to his old self.
