I think there are many good trainers around, you just need to look for one that thinks along the same line as you in training methods.
We show and train Arabian Derivatives, Welsh, Riding Ponies + more, the style of training and showing each breed is slightly different and it can vary from horse to horse , you need to bring out the good points in the individual animal and disguise the bad points.
As a judge is is amazing how many horses end up down the line because the handle has not stood the horse up well ( legs at odd angles ect ) or run it out well.
