Poor Duke! It sounds like he has a couple of things going it. First, it's very concerning that he is vomiting up water and not eating. He could have a severe GI illness, a foreign body, may have eaten something rotten, or could have pancreatitis. The rash could be due to a contact allergy. His symptoms of vomiting water and not eating are serious enough to require immediate medical attention. I would have Duke seen by a vet now to diagnose what is causing his symptoms so he can be treated.
