Tiny has it correct.
CA is extremely aggressive with all horses I have seen him work with. It's hidden behind 'being the alpha mare' which IMO is just rubbish perpetuated by people who know no better, and don't truly wish to become horsemen.
CA is a trainer not a horseman. Not knocking trainers, it's a job, but I wish some of them would not pretend about what or who they are. To trainers like CA, the end justifies the means. Mindy is a perfect example of that. A robot. No soul. No expression. No spirit, No life. Buy a motorbike if want a 'functional vehicle' . I see nothing to admire, except a small personality and a big ego.
One question for these type of trainers. When aggression and oppression fails , what do you do? When you have to work with one of the 0.001% of horses that cannot be overpowered or broken. The horse that commits to the fight not flight?
Answer? They do not have one.............
