Thank you for the link rhos.... Extremely helpful.
All Diddly is doing at the moment, is light road work, mainly an active walk, with spurts of working trot every 5-10 minutes.We also go for a private lesson, in a sand arena once a week for an hour. He won't be doing jumping of any kind until he is 5 1/2. Even then, it will be in a sand arena, or on soft ground. By the age of 6, I will be doing my first event on him (hes an eventer ;))
Conformation wise, he's very good. His front legs and hind legs are good, and quite correct.
