Both Brighteyes and BigGreyHorse make very good points. You have to work a little harder to keep a draft or cross to hold form and move off their back end, they like to plod sometimes, particularly the heavier ones like Belgians. But many, many people trim drafts very incorrectly as well - if she is long in the quarters and her feet look like dinner plates, get a new farrier as well! Their feet should look like regular hooves, only bigger. Flat soles, severe flaring, and cracking is common in drafts through mismanagement - if she has any of that, her feet are trimmed incorrectly.
