I have a horse who I am trailer training, well attempting it anyways. She is doing quite well, isn't at all afraid of the trailer, goes up into it with her front legs and will go all the way up to the front of the trailer leaving behind only about 5 inches of her back end and her two back hooves. How do I get her to put her back feet up in the trailer? I have tried luring her with treats and grain, but the problem is that she is long enough to reach it with her neck stretched out even without her back legs up in it. I do not want to destroy any trust and do not want to make it a stressful or upsetting experience, I want to keep it completely positive. I have also used praise, rubbing, and scratching too, not just food rewards. We start out at a walk, enter the trailer, she moves up to the front, but the back legs never enter. My trailer is a typical 2 horse side by side.
Any ideas would be appreciated. Thanks! Trish
