I've been wondering about this a lot lately... at what point in a horse and/or riders training are spurs helpful and at what stages would you consider them necessary(if you do)? I don't feel that my leg is nearly stable enough to use them and seeing that I currently school nothing higher than intro I have no need for them.
I've seen some people use them during a horses first ride and some that don't start until the horse is 1st level. Would they be used in the beginning of a horses training to make aids clearer or have them as back up if the horse isn't responding? Theoretically, spurs are for refinement and advanced communication, so I'm a bit confused as to why someone would ride a green horse in them(not trying to criticize, just honestly wondering).
