My three-month old miniature poodle has a problem when crossing the street on a lead with me - she constantly jumps around excitedly in front of me, trying to play with me. This is something she doesn't do regularly on the sidewalk. I believe that I accidentally trained her to do this earlier: the first few times I crossed the street with her I encouraged her to run across the street (I thought this would teach her to cross quickly without stopping), so now she thinks of it as exciting and playtime.
Now that I've realized my mistake, how can I teach her to cross the street quickly but calmly?
In case it is relevant, she is still learning the basics (sit, stand, down, etc) but she is a quick learner.
