Many times when our dog has vomiting or diarrhea we want to ‘fix’ the situation immediately, but in some cases it’s best to allow the body to do what it does best. In most cases diarrhea or vomiting is used as the bodies way of flushing out toxins and you will not want to use the medications listed in this article. This is especially true if you know that your dog may have eaten something that didn’t agree with him like old food from the garbage or poison. In this case give your vet or poison control a call and discuss the next best steps with them.
