Once Fat Pony was happy going through 2 noodles, it turned out not to be a problem to make it up to 4 noodles, then 6 noodles (Liberty Silver course) and then 8 noodles (Advanced Level on line course). Before long, he was walking through, trotting through and happily standing in the middle! Backwards needed a little more care to build it up, but soon that was no problem either. In fact, the noodle walk quite quickly became both the ponies favourite new toy! They would offer to do it if I was around and they also went through it on their own when they didn't know that I was watching. I don't know whether they enjoyed the noise it makes when they go through or whether they liked the feeling of it "massaging" their legs, but they definitely enjoy going through it! :-D
I started Horse Agility as a way of making groundwork more fun. It was something I could do with my semi-retired old boy and his small, cheeky, pony companion. What amazed me was how much it improved the ponies' general confidence in the process. I compete at Advanced 1 star level on line and at liberty.
