Today my miniature horse and I took a drive. She seems to have some problems sometimes trotting a paved road. So I have recently just let her walk our ride. Since she is exercising. Has anyone had the following happen to their horse? My mini horse is fairly straight in her walking on our rides. My mini and I live in a regular neighborhood. I try when driving her next to the gutter, but not in the gutter. She kept veering over to the gutter. I think this happened like 10 or more times, during our 1/2 drive. I had to use the rein from my left hand and tap with the whip with my right to move her away from the gutter. I don't know what was going on with her or what she was thinking. This was NOT normal for her to do this. She usually keeps her mind on her work, and walks pretty straight down the road. Does anyone have a suggestions? Am I driving her wrong . I try not to pull on her mouth , but I keep my reins not loose.
