bloody diarrhea with vomiting at his age is a concern for a severe systemic problem. One would worry about parvovirus or gastroenteritis from eating something he should not have to possibly an obstruction. Your vet can run some test to help diagnose the problem and provide with suitable treatment options. With sudden weight loss he may need to be hospitalized.
