The forefeet touching the ground first in trot isn't a useful way to judge on the forehanded-ness. Horses can be markedly on the forehand and still touch front and hind feet to the ground at the same time in trot. Instead, the rider needs to think about how the horse feels to him when he rides. Feel for 1.) difficulty turning and stopping 2.) the horse 'pulling' on the reins, the contact feels 'dead' rather than lively, springy, responsive(the horse can push a lot of 'energy' to the contact and still have a good quality contact and that contact still won't feel 'dead'). 3.) the horse carrying the neck and head low(the long low position is NOT a working position - long and low in dressage is a brief exercise, not a working position) 4.) a feeling like the horse is 'stepping into the ground' (the shoulders are too low and the strides are too short and stabbing into the ground) 5.) downward and even upward transitions are made with difficulty 6.) when the horse attempts to lengthen at trot, medium trot or extended trot, the rider feels as if the hind quarters are 'swimming' (swaying from side to side or wobbling) behind the saddle. 7.) the horse is TOO TIRED and TOO SWEATY after work that requires him to be more balanced and collected, and the sweat is in the wrong places - on the neck and shoulders rather than between the hind legs 8.) when given a walk stretch on a long rein, the horse puts his head in a 'stress relieving position' (nose parallel to the ground and in line with his neck) 9.) And the numero uno clue that the horse is on the forehand: the horse gets faster and stronger/harder in the bridle as the ride continues on.
