Most common thing I have come across when starting a reining horse is the basics such as the requirements to neck rein, stop, back, turn (l & r), w/t/c, and respond to weight shifting. My mare does all of this and more, but currently I am working on lightening her mouth to the point where I don't need a bit to stop turn and back etc...I could do so just by shifting my weight. We are progressing, but she seems to be getting bored in the process so I am considering starting her pivots.
Problem is, as much as I try, she does not want to move off of her back end. She puts alot of her movement off of the front half of her body, and when I ask her to rein into tighter turns eventually leading to a pivot she arches her neck and just does everything she can to avoid it. What can I do to relax her neck, bring her to move her body off of her back end, and begin the steps to slow pivots? Anything helps, thanks so much!
