This sounds very serious. I recommend an exam with another veterinarian if you are unable to get a diagnosis and effective treatment. Murphy may need hospitalization until his condition improves. I agree this could become life threatening so I would bring him to a specialist for a second opinion soon. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Murphy.
