Training usually works better than bribing. With training, you end up with a horse that habitually looks to you for guidance and is calm if it is not sure what to do.[/QUOTE]
I am pretty sure that the poster meant ‘bribing’ tongue in cheek. What is really happening when you give a horse a reward you are conditioning it for a response.
The horse learns there is a positive reinforcement for a desired behavior. Positive reinforcement is proven to be the most effective method of training in animals, in that it creates a lasting behavioral modification. A secondary reinforcer (think clicker training) also works very well in conjuction with the primary reinforcement (in this case, treats).
I have never in all of my time working with horses heard that horses should not be fed treats because they associate it with taking food from you. I have heard other reasons why you should not feed a horse treats but this is not one of them. This sounds like an older methodology, remnant of dog training – even now trainers are making a step back towards reinforcing behaviors with treats because it has been proven to consistently develop a conditioned and reliable response.
