Our almost three year old MFT is completely bombproof, leads well, responds to whoa, and does not mind a saddle, reins or rider. This is the first real problem we have had with him.
Last week we decided really ride him for the first time, I got on and my Dad led him around a bit, all good; but when I try to get him going forward myself no amount of nudging, clicking, kicking or even a little slap on the rump would get him moving. My Dad comes back and he leads him around easily. Also this last week I have had some him lead him forward every time I nudge and click just to give him the idea, still nothing. Any advice would be much appreciated.
