On the question of x-ties, I think it's a good idea to teach a horse to accept this & other types of restraint, as they might have to deal with it some day, for veterinary or whatever else. But I don't think it's a good idea to just bung them into this situation, or make a point of x-tying them generally to effectively force them into things. Eg. many people talk about not being able to saddle, worm, wash, whatever without x-ties. IMO this is not the best way to teach a horse & I wouldn't personally do those things on x-ties until the horse is comfortable standing untied for them.
Riosdad-thats cool that you do shoeing. my horse has pretty flat front feet and the farrier always told me he needs shoes onhis front bc of that. is shoes really necessary for flat feet?
Sorry to go OT... Conventional shoes are definitely not necessary for flat feet, and I personally don't think they're very helpful, except palliatively. Shoes often (tho I don't believe always, by any means) perpetuate the problem too. They raise the sole another 1/4" or so from the ground, so on level, smooth surfaces do provide a bit of a buffer against small stones, but on any other surface, they provide no protection to the thin, weak soles, and just as importantly, on firm ground, provide no support to the sole/frog. For the sole to become strong & thick & concave, it needs support/ground pressure, and the walls/laminae needs to be relieved of excess pressure, rather than being fully loaded. Therefore for flat footed horses, I think keeping walls short & well trimmed and using boots &/or pads to protect & support the bottom of the foot are the better options.
