This is an emergency, as your puppy could be suffering from a parvo virus infection or at least a serious gastro-intestinal condition. You will need to take Zeus to a petER now as bloody vomiting is pointing to a life-threatening condition. He will need an exam, blood work, possibly an xray to rule out a foreign body obstruction or an intussuscepted intestine. If he suffers form parvo he will need iv fluids, antibiotics, and pain medicine, and hospitalization.
