For those of you who don't know, Dex is a mustang we adopted from the BLM back in January. He's 5 years old, 14.3 hands, & is a Draft X. He's going well under saddle & is just an all around great horse. So what do you think of his trot & his headset? What discipline do you think he would do well in? He's going to be used as a trail horse, but I'm just curious to see what you all think of his movement. The pics just don't do him justice. Thanks in advance for looking!
