Is there anything I can do about helping Lacey not be swaybacked?
She has a very mild one right now and I really really don't want it to get worse. Are there any exercises I can do? I think I remember reading somewhere that working in a long and low type frame or something can help, should I get some side reins to help Lacey with that when I lunge her? She's great at the walk, really working through herself, but at the trot her head always comes up and I'd bet she hollows out her back too (she stills tracks up) which probably does not help this issue at all.
Should I be padding her saddle pads differently?
Also: how do you decide when it's time to retire a horse from cantering or work in general?
Some days I totally feel like Lacey wants to work as hard as I'll let her while other days she's just so unenthusiastic about doing anything that I just wonder if it's fair for me to continue riding her twice/three times a week. I want to do the best for her and not what would be the best for me, unless our bests are the same...
ETA: I've been riding her in a western saddle for the summer and I was wondering if that was the best choice for the swaybacked issue. I'd kinda think it was since my weight (all 150lbs of me, lol) is distributed more evenly than it would be in an english saddle... Thoughts?
