I am so sorry to hear about Demon. With these symptoms I would get him in to the vet right away. We would worry in a young puppy like this about parvo virus https://www.petcoach.co/article/parvovirus-serious-diarrhea-in-puppies-dogs/ which needs to be treated aggressively. The safest thing to do is have the vet examine and test him. We can see vomiting and diarrhea for other reasons in puppies but we always want to rule out parvo virus to be safe!
