Horse doesn't use back
ive had this horse for about 5 years now and even before i bought him he had some issues. his feet had been shod wrong when he was a colt which in turn caused him to not use his back while he walks, trots, etc. and develop a sway back. i have a ton of exercises that i am doing with him, but for the past year now there has been absolutely no improvement. ive tried cavalettis, trotting poles, back raises, side riens, new bits, stopped riding with a saddle, streches, hills. i know it doesnt happen over night but after a year of no improvement i need some new ideas. any help would be great thanks!
