Furbabymum, I know exactly what you mean. I have one of those ponies. If I remember he height correctly she's just over 12hh. One day we were trying to gather the herd into "the quad" a big square pen attached to my stables that we use to temporarily confine them for stuff like fly spray, etc. This day thay were being very difficult and didn't want to come in at all. So they started running faster towards the big camp gate, a std farm gate and about as high as she is. What does madam do, she tries to jump the fence next to the gate. Her front end made it, but her hind leg hooked on the fence post, tearing a nice big hole in the fleshy part just above the hock.
