So, together, my mum and I have three horses. The original plan was to have two, but I won't delve into that story. We have three now, and not always a third rider, or a rider who can handle one of the two of my horses. My mum enjoys trail riding, just walking around the farm on her old horse. She's a fairly nervous rider so she doesn't like to go alone, and she doesn't like to ride my horses. Our farm isn't set up to leave behind a horse (because they scream and run around, and have threatened to jump out of their stalls), so it's either one horse goes, or they all go. I thought ponying would be a good idea, and I think it's a good skill for a horse to have. However, the mare I usually ride likes her space, and has had a tendency to kick out at other horses who get too close. And my gelding is somewhat of a space cadet. He gets anxious on the trails, he can't focus on one thing, everything freaks him out and he tends to be energetic. I'm afraid of him taking off ahead of Nelly while being ponied, and having the whole thing be a total train wreck. Is it going to take a lot of practice in the arena before they become a team at it? Should I be teaching them voice commands? How would you deal with them?
