When I attended college and majored in Equestrian Studies one of my ‘test’ was the ability to mount up without a girth. The instructor didn’t just loosen the girth – she completely removed it. The whole class got a chance to try with the same patience horse. Thankfully the horse was around 15 hands and had a nice set of whithers…but the point was also made.
Do you mount and dismount from both sides of your horse regularly?
