How can you tell what breed of horse you have?

An Arabian horse has a dished face along with a teacup (small) nose. It also has a high held tail and a long neck with smooth circular hindquarters and muscular but slender legs. A thoroughbred does not normally have a dished face or small nose, and looks more muscular. The neck is also shorter, the tail generally lays flat, and thoroughbreds have more of an upright stature along with longer legs than the Arabian. Thoroughbreds are tall in general. However, a horse could be an Anglo - Arabian, an Arabian thoroughbred cross, in which case the horse would share these features. Also hence the movement and spirit of the horse. Arabian have floaty, free flow trots while thoroughbreds are bred to have smooth trots that cover ground quickly.
