My dog was just given the parvo shot about 3 days ago and 2 days ago she has been vomiting white foamy stuff and has like water diareah, it is some times red in color and smells rancid. Her brother had the same shot and he got those symptons and he's fine now. I'm really getting worried cause she won't do anything and we don't know what to do. Do I need to take her to thje vet or just wait it out? She is 11 weeks and a lab/shephard mix
