Y'all I didnt mean to offend you in suggesting that you were just tring to start something. Just covering all the bases since it seems like picking on the WP horses has been the big thing lately.
I would say a pleasure horse is started the same way as any other show horse. The finishing is just going to be a little different as far as what you expect from them. Spur stops are popular but you certainly don't need it to for a pleasure horse. You train just for a good, broke, and sensitive horse that doesnt need a lot of handling through the cues.
And as far as cues go...everything is based off of moving off the leg. From there you gain shoulder, hip, and ribcage control.
Here's an example... This was a filly I started in pleasure. As for her speed all I did was teach her that when I lay my calf on her with some rein, she's to collect. (gradually using less and less rein) Unfortunately she started to get lazy with it and you'll see her cadence waver here and there. (meaning she needs to be pushed up into her jog)
You can see some shoulder stuff in here too. Just like I said before...moving off the leg exercises and evolving from there.
Here head carriage was her own doing. I just made sure she was soft in the face and she just settled into a frame that was comfortable for her.
That's pretty much all I have right now.
I suggested going to see that show because its an enlightening experience. I often go to shows to just watch and learn...even with no intention of competing in that dicipline. Its just interesting.
