In dogs, some of the most common causes of throwing up blood include: Prolonged or severe vomiting of any cause that is left untreated. Significant vomiting can result in inflammation of the stomach, upper intestines, or esophagus that may lead to bleeding. Intestinal parasites (such as Giardia)
so i'd advice that you see your vet as early as possible.
