Poor Coki! I would be worried too, as having blood in the vomit can have very serious causes including GI ulcers, eating something toxic, GI tumors, bacterial or viral infection, a foreign body, or clotting disorders among others. I would have Coki seen by a vet right away for a physical exam, blood tests, urinalysis, and possibly x-rays. Once the cause of the vomiting and blood is diagnosed, the vet can start treatment.
