Take it to the clinic they can help you
I have 2 puppies a Spanish coker and a Maltese, when I get diarrhea and vomit what I give them pedialite every 2 hours but if the diarrhea and vomit comes with blood is the parbovirus that has, is a parasite that gets into the small intestine and reaches the heart and kills them, but do not be alarmed when this starts to happen you have the solution give garlic shredded with water and you will see that the next day is like new, keep giving pedialite while recovering when you are well the same he goes to look for his own dog food and it means that it's fine.
