Walkers are just that way- especially show walkers- they usually keep faintin goats with em to make them less nervous.
Mine likes to be wild eyed and look at everything trippin over her own feet- I just give her a jerk of the reins (if she's lookin left- ill jerk the rein right- etcetra.. not a huge yank just a small jerk jerk of the rein) to tell her to pay attention to me and look ahead- not be lookin all over the place bein a bonehead, lol.
For the not standin still for mounting- you need to mount and just sit there still for a few minutes- jump off and do it again till she learns to stand still when you mount- when she does stand still wait the few seconds and then go off down the trail or wherever you was goin to show her that's what you wanted and if she stands still then you can go.
Our walkin horse was supposed to be 'child broke' and was not even green broke! She had been used as a leadline horse for children.. go figure!
lots of work and dedication is what makes a good ridin horse. How are her cues? What all does she do?
