I used to compete in showjumping and liveried at a yard that had showjumpers. We used to get the 'back' man(as we used to call him) out every so often and he would normally just pop whatever needed done or realligned there and then and that was it till he came again. Only one horse ever needed a lot of treatment but this horse had a lot of muscle wastage etc so was expected but apart from that it was all fine. We used to get him out 2-3 times a year whether it was needed or not tho - he was never really called in just to help a horse with problems so in that case I'm not sure.

ON another note I am at the moment seeing a chiropractor and have been going twice a week for almost 4 weeks and havent noticed a difference just trying to decide how long to give it before I decide to quit so not totally convinced with chiropractors to be honest
