Vomiting and diarrhea can be a sign of a number of different diseases in a young dog. Intestinal parasites, partial obstruction from ingesting a foreign object or some infectious diseases could cause these signs. If the vomiting and diarrhea continues she could become dehydrated, and black stool could be a sign of bleeding in the stomach or intestines. I would recommend making an appointment with a veterinarian. You may want to try to collect a stool sample to bring with you so they can look for intestinal parasites - use a clean plastic bag and place in the refrigerator if it is going to be more than an hour or so before you are able to bring the sample to the vet. I hope Rosa is feeling better soon.
