There is no browse on our property, so I take my new-to-me Nubian goats, 3 yr-old doe and 6 mo. wether, on a daily 'browse walk' down the dirt road across the street from us. They are pretty good heading out, but when Derby (doe) decides it's time to go home, she just about pulls me off my feet. Not good as I already have bad knees and ankles and am terrified of falling and making them worse. I usually pass the leashes behind my waist to use my weight to keep her from taking off, but the pulling is awful. I 'whoa' her and make her stop, take a good breath, and start again, usually with a good grip on her collar. But I'm afraid she'll get away from me and dash out into the street which doesn't have a speed limit and does have some crazy drivers. How do i train her to be calm heading home?
