The most likely diagnosis for a puppy with Jack Jack's symptoms is parvo virus. I suggest you get him to a vet as soon as possible for an exam and parvo test. This is serious and life-threatening. Do not try to continue to treat him at home. He may not have parvo as there are other things that can, of course, cause his symptoms but regardless of what is ailing him he is very sick and needs veterinary intervention.
