big shout to obedience training, good for you, good for the dog, also find a good dog walker to work on the skills. My dog has too much of a "rabbit factor" ("ooh, let's go see THAT! Right now!") to do the bike thing and I also feel strongly that it can put you....or your dog in traffic or danger.

but with a lot of work, and treats she walks very well on a loose leash now.
