We have always let Nug, off leash. We started when he was 8 weeks old. And I just gave him a little treat every time I called him and he came back. My husband and I go hiking a lot and some of the places that we go there is no way to hold a leash and climb. It also helped that my older dog magoo has alway came when called and Nug mostly learned from him. Try using a very long lead so that Riley can get some distance from you, with the lead you will always have control. Never chase, run the other way and they will almost always turn an follow.
