In the past month I've been doing april battles' yoga for horses and have seen some small improvements in his flexibility in lateral flexion. I was surprised today to see his blanket covered in mud on the other side, the right side.
My newbie question is: do most horses roll on both sides, is it a comfort issue or flexibility issue? I've seen the 32 yo qh mare I ride roll only on one side in the 3 years I've spent time with her.
I would think younger horses have no problem on either side, but older horses may have a side that is more comfortable for them. At any rate, I am pleased.
