New here also:)
I can understand why your BO wants your mare...she is a Beautiful Buckskin Overo...kind of partial to paints:):)
I noticed you just bought her 4 months ago...dont listen to other people, about "her doing better with the BO". To me if the BO is a reining trainer..I am sure he sees her color and confirmation, and knows that THAT SELLS...I am sure h could put alot of training on her , and the turn around and sell her for a very pretty penny!!
Know that you are giving her your love and undivided attention, and feel good in the fact that there are so many out there that want your mare for themselves!!! Bask in that!!!
You and Cheyenne are just getting to really know one another beer, and remember Best friends don't know all of each others secrets overnight:):):)
