OMG if things couldn't get any worse. My Grandson was eating one of those m&m ice cream sandwiches and he said Mana Pixie got an m&m

it was a mini m&M and milk chocolate.
Now she is throwing up...she threw up her whole dinner and there was a lot of mucus in it. It was so flemy it was like snots....(sorry for the description). I called the emergency vet and they said that if she continues to throw up bring her in. She is sleeping now. I am so worried
