Hi, so I was told that horses should always have splint or sport boots on when being worked in the round pen. I have a 50-foot round pen and my Quarter Horse mare wears sport boots whenever she is worked in the round pen. But what about my minis? I set up some small jumps in the round pen and they easily jump over them without any problems. Should I put splint boots on my minis? If so, should I buy splint or sport boots?
