Our bulldog sleeps in her crate every night... but last night I let her try and sleep with my 9 yr old daughter for the first time. She stayed awake until around 4 am then threw up yellow bile and white foam. I moved her to her crate and she threw up yellowish green bile in her crate. She ate about a 1/4 of her breakfast and threw up 3 more times and she is drooling like crazy. She then slept the rest of the day. She got up around 5 pm and threw up again, ate a little food and threw up again. No other symptoms and stomach does not seem to be in pain... should I be worried or wait and see how she feels in the morning before I call the vet?
