Super Boxer
Maybe I'm lucky, but I haven't needed anything to keep Porter from pulling. Just took some training. Granted that's as long as there are no squirrels or frogs around for him to chase.
When I started walking him I kept the collar up pretty high on his neck so he wouldn't pull...and he got so used to it that now he walks right next to me with slack in the lead. He knows heel well now too.
