We were very very patient with my horse until he finally got in the trailer, little by little. I reached a point at which I thought this would never happen. Now I am so surprised and overjoyed that he walks right in! We achieved this by taking it very slow and rewarding him for each step by petting and backing him out. When he finally put four feet in we would give him a handful of grain and he would back out. After doing this a few times he walked in very easily and without hesitation. So, we decided we must stop relying on grain. He still walks right in, but backs out after a few seconds. He stayed in longer with grain. We are thinking that we just need to keep practicing, and when he stands in there longer than usual reward him with petting and backing out. Is that a good idea or is there a better way?
He is a 12 year old gelding, he was free from a neighbor-who received him from a friend who didn't want him. I know almost nothing about his past but he was untouched for over two years before I got him
