I have a 17yr old appaloosaXquarterhorse, and he was only in a trailer once. It was a homemade contraption, it didn't have a roof and was very open. My 20yr old gelding walked right into the trailer. But my other one had to be loaded backwards. I didn't want to do it, but every time I walked him to the trailer he would plant his front feet just inches from the step (it had no ramp). I've tried everything to get him in, and nothing worked, except for that. Once he was in he was fine. But how can I help him realize that its ok to get into the trailer???
He can be very difficult sometimes.
Any advice would be very helpful!!
