Jazz is an 8 year old Quarter Horse mare. She's about 15 hands tall. Jazz will test her rider but once you assure her your boss, she'll do anything you want her to. She's very very laid back and easy going. She's a really nice trail horse. Nothing phases her and she doesn't spook. Stands for farrier, tacking, mounting/dismounting, grooming you name it. We bought Jazz as my husband's mount and they have clicked beautifully. She definitely prefers men though she's really well behaved for women too. She just gravitates to men more.
