10 yr gelding has no self confidence.. In a group of people he refuses to move forward, he backs into bushes, bucks/rear. I try and keep his feet moving, but it doesn't work. I wear spurs or carry a crop he still bucks/rears. He hates standing and then starts to spook, spin, prance, paw, and chomp at the bit. Anotherproblem, is he refuses to be the lead horse on trail rides when I am with another horse.
