I have a 13 year old Paso Fino mare. She had a lot of training issues when I got her, wouldn't gait, always trotted and was strung out, lots of respect issues. She has come a long, long way. She is now gaiting but still does not like to collect, which is a shame because when you get her collected she is a great Pleasure mare, and even at her age could still potentially place in a pleasure mares class. The problem is she hates arena work with a passion. For me it is usually the only place I can ride her and I'd love to show her eventually. I have had her for almost 2 years now, working with a great trainer who unfortunately I will have to leave soon due to moving. I suspect her hatred of the arena mostly stems from one previous trainer (who is no longer training thank the gods) and being allowed to get away with everything as a lesson horse. Is there any way to make the arena enjoyable for her? Perhaps even make it so she can make it though a class without throwing a pissi fit (her nickname is Pissi, just her personality)?
Btw I do have her on a mare supplement, originally on Mare Magic and just changed recently to SmartMare Harmony.
Here is a video from several months ago. We are currently working on bending. I am not the rider: https://www.youtube.com/watch?v=YohEtJAt4IY
She is currently ridden in this bit: Western BS Silver Dot Med Port Roller S-Shank Bit - Horse.com
I've tried her bitless and in snaffles, she hated it.
