do they struggle to stop him during this jogging? my mare jogs, but is very easy to stop and then make her walk. she will continue to try to jog every now and then, but always easy to stop.
Have you asked if the horse feeds off the riders feelings? ie if you are nervous if he jogs will he be worse? my old mare doesnt care less about how the rider feels, but my young mare is very sensitive to my feelings and acts exactly how i feel.
Personally, i reckon it sounds like it is very promising, i wouldnt and wasnt put off by a joggy horse......if its been a beginners horse before then it cant be that bad really.
and also....it isnt wasting peoples time, if the jogging doesnt scare you then you would buy him, but you dont know until you try....
