Thats what I've been thinking just wanted to make sure! If she is beside me then I can easily tell her to sit in a random situation. For instance, someone creepy or another dog trying to bite me, etc
Exactly why you would want them in a heal position or walking beside you. It takes some time to get them to learn where to walk but once they get it it's great. I don't even have to use a leash anymore which I love. Zeus will never leave my side unless I give him the free dog command.
