We always had to keep Jo on a leash, so all I can say is that you will get used to it and she will as well. It's much better than the alternative to be honest. I remember the couple of times Jo slipped her leash. She never really learned "come" very well, so it was always a desperate chase to catch her before she got hit or something.
