Hello again;
My dog's vomit varies; sometimes it's clear & sometimes it is yellow.
He also likes to eat grass while on walks, usually goes for the rough crab grass. Sometimes he pukes up the just eaten grass & sometimes not.
I've tried to give him pepto & tums tabs but he spits them out... kinda weird for a critter that's "part goat" & will eat anything if left to his own devices... I am happy to hear that you don't think it to be any kind of blockage Thanks for your input...
Oh, about the food change... I do sometimes give him something else; he kind of likes Beneful & doesn't give me problems about that change, but if I put something in his dish he's not familiar with he'll look up at me as if to say "what's this stuff?" LOL
