If your boston's show the puppy who is in charge, the puppy will always remember.

We have had Jasper(boxer) for 4 months, and Piddle(shih-tzu) is in charge, Jasper will not bother him at all, would never take anything from him or near him, and he knows what not to do near or to Piddle, basically he has to stay away from him, or Piddle will growl, snarl..etc, And Jasper knows.
