I use a wrist-rocket slingshot and marbles. They sting like hell but
don't break the skin. One hit is usually enough to send a marauding
pooch on his way at warp speed.

That's a good idea. I won't have to ask my neighbor before doing this.
I haven't used a wrist rocket in forty years, what range are they
accurate too? The dog runs from me on sight.
