My 5 1/2 month old toy poodle has diarrhea (it has mild, almost no blood in it) and she is throwing up. She was fine this morning then she started vomiting a faded mustard like substance.  We just got her and she does not have her shots yet. She doesn’t seem sick at all, she still seems very eccentric as always. My grandma gave her something to eat and soon after that she threw it up. Please help! — Eli
