My horses are all basically the same under saddle. They of course have their own personalities and differences but once you can ride one you typically can ride them all unless the horse only likes me (I have a few of them). That being said, every trainer should say the same thing that once you can ride one you can ride them all. We have a recipe for success and stick to it. My recipe is no force, no spurs, no tie downs, no gimmicks.
If you do your homework on the ground and “set them up to succeed” you will have a much easier job in the saddle and both you and your horse will enjoy the ride. You want your horse to enjoy being ridden and look forward to it. Don’t make it miserable for them by riding them to a sweaty lather and poking them in their sides with spurs until they are swollen and tying down their heads to force a pretty picture. That’s going to chase away any “try” or respect your horse has left.
Horses can feel a fly on them and twitch any part of their body to get it to fly away. Why do we think spurs are a needed tool?! Horses use their necks to keep their body balanced. Why do we think tying their head down will teach them to collect? Why do we feel we need to ride the horse to a sweaty lather in order to achieve a result? WE DON’T!! STOP DOING THESE THINGS! Train with softness and understanding and you will get the same in return. Take the time.
