Hi! Our girl is 5 1/2 months now, and she's still learning the leash. She constantly chokes herself because she wants to walk faster than I do. I stop periodically and make her sit, more so to calm her down and let her catch her breath, and if she is walking right by my heels like she should be, I praise her out loud and give her a treat. Whenever I want her to come in from being outside, I get down on my knees to her level and call her, because she absolutely LOVES it when I'm down on her level where she can lick and paw at me and knock me over. I have also taken to using the milkbones to get her in. But there are times when she absolutely refuses to come in when I do all that, so we end up running around the back yard, me chasing her and her laughing at me. There are other here with tons more experience than I have, but I'm just trying to find out what will work for us. Some things work, some don't. Good luck to you :-)
