Question
Are there some horses that are beyond hope and will never make good riding horses, because they have been so badly treated by humans in the past?
Answer
While there are some horses that have been so mistreated that they are virtually unusable, I believe that the number is very, very few. If one fails to save a horse for some useful activity it is, in my opinion, virtually always because we are short of the mark in understanding how to meet the horse's needs. I have literally never worked with a horse without significant improvement.
Sincerely,
