I'm glad you joined in Foxhunter - I;ve made my comments on the other thread too and as a fellow Brit who also spent a lifetime riding on main roads I have never desensitised a horse in my life. They have to learn to deal with things as they come along. They learn to trust me, they learn to do as they're asked and that's it.
I had never heard of this expression until I came here and it was popular among the Parelli crowd - and Rick Gore is constantly 'sacking horses out'
I sometimes think if you fuss too much its like telling the horse you expect it to spook. Maybe its the rider who's being desensitised to believe the horse wont spook. I don't know. If it works for you then knock yourself out, whats the harm, its just not for me and was never a part of the UK horse world I knew up till 5 years ago
This pony had been broke 2 months when we took her to a little show and the girl on her who was a very tall 13 year old who used to ride for us asked me if she could go in the Handy Pony with her - she had never seen any of the stuff before and won the class. Really bad camera angle as she was actually a really pretty thing and not an odd shape!!!
