My daushund ate peanut butter Monday night. Late yesterday afternoon she vomited what appeared to be peanut butter. This has been the only time she has vomited. But beginning later last night she developed diarrhea. It isn't bloody or tar looking, but happening about every couple of hours. She is drinking and has not lost her appetite. Other than diarrhea and not wanting to lie down on her stomach she doesn't act sick. I am debating if I should make an emergency trip to our vet or see if it is a bug that needs to run its course.
