So, i have recently got a new pony on loan and he is very forward going, which is good for me because i love a nice fun ride! I'm used to dealing with bucking and rearing etc, but this pony has a habit to bolt. I have dealt with bolting before, a few times but just want some suggestions. I was out hacking him, (only my second day of loaning him!) and we were riding in a big open field with my mum walking on the ground with my dog. I tried walk and trot first because we are still getting to know each other, and he was fine so i had a short collected canter. I was having to hold him back alot to keep him collected though! anyway, so a man came out from the hedges when i was cantering and it went from a calm canter to a mad bolt, with complete loss of control, and it wasn't just a little canter away it was tearing around the big field at full pelt. i just sat back, and kept calm etc as i didn't want to panic him more or get into a fight by pulling and pulling,so just held and released. i didn't realise the man was there with his dogs til after so, not sure if it was that or not. he did throw his head in the air making it hard for me to stop him, so i am going to put him in a martingale. my mum said he opened his mouth too, so i may put a flash noseband on him. But he does have a light mouth, hes in a loose ring snaffle so i don't want to be pulling at him! Any suggestions?
