I think we have done as much as we can at the walk. She alternates a nice big stride, head nodding, relaxed...with a tight stuck stride, very light in the front end, ears pinned. Seems to be random. She will move sideways to light leg pressure, strong leg gets her stuck, but ANY leg got a bad reaction a week ago. She totally forgot herself and showed me that she neck reins yesterday.
I would like to just walk her until she feels like she would just walk forever, but I think we would both die of boredom or old age before that happens.
Time to start mixing it up and work on some walk/trot transitions.
