This really works for Izzy for our clicker training sessions and we only give her this during training. Once the package is open you can refrigerate - we cut into teeny, tiny pieces to help train Izzy and this should help with leash training. Start with loose leash - then start to walk - when she stops you stop and you don't go until she starts to move again - then when she does you praise her like crazy and give her a treat. I use the clicker so she is well tuned to that and knows that she has done something good for the clicker to go off. Izzy can sit, lay down, walk on leash, go to her bed on command, wait, leave it, etc., etc. Clicker training is awesome - check out this site too:
