Are you familiar with working dogs? I have had a rottweiler and a GSD and my vet (faculty at Cornell Vet School) and my dog trainer recommended using a pinch collar and doing corrections by snapping the leash. That being said they also recommended against the long flexilead (i think thats the brand) leash and/or having the window down far enough that the dog could jump out. My dogs never would have walked in front of me on a leash like that.
