welllllllllllllllllll, I own a mustang and have done much research on them before I bought him. Their tempermant is usually amazing, they are life long partners, super social, and very trusting to their owners (i guess any horse can have this). I was told by my trainer that mustangs can be great little jumpers because they are built for athletics, but everyone is right, they are super stocky, probably not the most graceful. Conformation wise, prob not the best, but for me im not going to be showing or going pro....maybe dabbling in jumping, but nothing spectacular. I love my baby for his personality all the way.
