yes normally there is underlying problems such as saddles and teeth or incorrect riding, and a good therypist no matter the disipline will try help as best they can to identify - from what they can tell- possible causes but i do regular maintenance.. every 6-8 weeks and bits in between myself- and now c.p is getting worked pretty hard... at least an hour training 5-6 days a week with trail rides thrown in there too. i have made a special note to get another one soon as we are starting to ask for more collection, and harder work- shoulder in, travers, half pass, and im being firmer in my riding too- not letting him be a slacker!!! we have a purpose now and so its training not just riding when she came out the other week- she noted c.p was a bit sore all over- which ment he was just really starting to use himself properly- it wasnt confined to one spot so i was happy about that! ill get one early as i have summer series which i am wanting him to be moving well for and also the training regeime is pretty full on so dont want him to be sore and want to catch it early to avaoid any soreness issues before it happens i know i need one!! but he will always come first! hahaha as is always the case with horsie people!
