Yes! Very good! We had seen larger dogs with Gentle Leaders for years at the park. When we got Darcy, a stubborn little min-pin, we struggled so much walking her that we wondered if there was a small size GL model. There is! We found one on Amazon and as with your girl, the change was immediate. Occasionally, people ask if she is wearing a muzzle. We tell them no, it is "power steering." They laugh and immediately understand. Bud undoes the nose loop for the fast-walk part of their daily excursion. Darcy looks forward to that and behaves perfectly. It was a learning curve, though. Glad it is working out so well for you.
