In Bertrams fifth ride I decided to all out and introduce him to being ridden in the saddle, even though he hadn't been ridden in weeks due to time restraints. He certainly impressed with his lovely nature!
NOTE: While breaking horses in appears easy, my horses have had very good foundations and have had no bad experiences or associations to humans. I have also started countless horses under saddle and am very attuned to changes in the horses survival response, and know how to quietly redirect the horse to avoid something going wrong. Starting horses under saddle is a skill and should only be done by an experienced person. A bad start under saddle can negatively impact a horse for the rest of their life.
