I live this scenario every day. My pup never responds and isn't concerned about the display my 14 y.o. shih tzu puts on. My solution? They are never together. It's not fun, but my old dog won't hush and accept that the pup is here to stay. He gets to stay in the master suite when the pup is out. Oh well.
