When you see another person/dog try refocusing his attention with treats. They will have to be VERY yummy treats if they're going to distract an 11-month-old boxer

but do all you can to keep his attention on you and even get him to sit or lay down as the other dog is passing by. Keep his attention on you until the dog/person has passed.
If that doesn't work (or if you don't have treats on you one day) try changing directions instead when you see someone. That will at least let him know that now is NOT the time to play, he needs to be focused on what you are doing. If you ever get to the point where he can greet a dog calmly, then let him do it (and give him LOTS of praise for it), but as soon as he starts acting up turn right back around and walk in the opposite direction.
