Welcome to you and to Hooch. I'm sorry he's not feeling well right now and I'm very hopeful there will be help and support for you here. Can you give us a bit more info..about his throwing up..when did it start? Any changes in diet or treats? Does he seem fine other than the throwing up? is there any chance he ate something?..like a piece of a toy...etc? He is a bit older than my Jake and I'd be very concerned also.
