First, you might want to pick a few other treats (like cheese or something) so you can use different treats each time so the hotdogs don't get boring. Aside from that, just keep practicing the leash walking exercises you learned in her class. You may need to go back to less distracting environments and practice more if she's not doing it in distracting enviroments as well. Leash walking is a slow process. But I definately think keeping her guessing on the treats will work. By making yourself a "jackpot", she'll never know what she is going to get.
