Back to the subject of buddy sour -- my own prescription, and part of my upcoming book Chickens on Horses (we should write on what we know, and I have 66 years of being afraid of horses) is to just go lead your horse away from the herd. I go 3-5 miles on my outings. We get to see all the neighborhood horses in their spring hysteria, get up close and personal with rattling trailers and flapping tarps on moving vehicles, and we get a nice long session to refine our leading manners. By the third day the dancing and rearing is all gone, and soon after we can start riding again. Even us chickens.
such good advice! I remember watching a show about how they train the Lippizan horses, and they do a lot of just taking them out for walks. They are gentled in the most natural and non confrontational manner. It's amazing. Those horses also get years to be out in a herd, running free, to grow up, before they are asked to work. They are constantly petted and loved on, handled, taken for walks, etc. and these are STALLIONS.
