For western pleasure you want slow and consistent gaits with (ideally) the horse's nose just outside the vertical and his neck long and low, so you will want to work on getting and maintaining a slow but steady pace and consistent frame. The lope is the "money gait" in western pleasure, so you will probably want to work on it a lot. Also, keep in mind that your horse may need training to stay slow in rail classes if he is one of those horses that likes to race all the others. In America, we are usually supposed to ride adult horses one-handed in western shows (although you might check the rules where you are in case they differ and younger horses are often allowed to be ridden two-handed), so you will want to use a bit that can be properly used one handed (often a curb), and show in it. Because you want a loose rein (again, at least with the one-handed riding in America) you want basically no rein contact, but if you must use the reins you want contact with the bit to be brief and most riders will only pick up the reins to "fix" the horse and then put their hand back down again. Because of this, you will probably want to work your horse to be sensitive to your leg. In my experience, it was also important to know how to do at least a half-pivot (turn on the haunches where the back legs stay stationary) with your horse. You may need to train the movement step-by-step. One of the big things I was told when riding pivots was to not let the horse step out of the pivot and rush forward, but to make sure he completed the full movement and did not move forward right away.
For both trail and western pleasure you will want a horse that can responsively back. Trail patterns will sometimes require you to back at an angle, so working your horse to bend his whole body while backing will be helpful. A lot of trail obstacles can be a little spooky/weird to the horse (I've had to take things out of a mailbox for example), so make sure to desensitize your horse a bit! A lot of patterns I've done (if not every one) have had a "gate" that I had to open and/or close. To do this properly, you will need a horse that is able to side-pass (move in a completely lateral step) and be responsive to you when you ask him to slow down or stop. Side-passing is also sometimes required over a single ground pole, so it is not a bad thing to work on! If you can find or build a trail bridge to practice on that would also be very helpful, especially if your horse has never gone over one before! You might be able to find a few Youtube videos of horses of the same breed as yours from big breed shows to get an idea of what the ideal is (There should be plenty, especially of Quarter horses at American QH Association shows!)

Il cavallo in modo delicato, ogni volta che si scomponeva lavoravamo così, ad un certo punto si arrivava che bastava mettere le gambe leggermente arretrate e usare i polpacci che già il cavallo si metteva con l incollatura giù naturalmente😃
Ciaooo, un mio istruttore specializzato nel western pleasure mi spiegava che quando prepari un cavallo per il western pleasure è importante che il cavallo abbia una posizione naturale però un po'raccolta, e mi faceva lavorare in questo modo,se il cavallo era al trotto o al galoppo nel momento in cui si scomponeva o era. "aperto" ci faceva mettere una leggera pressione con i polpacci in modo da continuare a mantenere l impulso e con le mani raccoglievano il cavlloa
