I use the treat system too during training, but my "Punisher" below, sometimes gets stubborn if he knows a treat ain't coming. I also have the ecollar, but don't want to go that route yet. My dude also doesn't like bikes or joggers, and he sometimes thinks he can take on a passing car when we are walking. Once I drop the leash, his "tough guy" act goes away, as if he thinks it only works when I'm hanging on..
