Loading my horse into a trailer problems?

my girly had the same problem last season, but what we did was we where very patient with her and we took our trailer and put it in the field with her(and my other horse) and we tried that and it worked OK but still not good enough for her so we took our trailer backed it up to where it is when we load her up(that also helps is always keeping the trailer in the same place during loading so she knows her surroundings and she loves her grain(what horse doesn't) and we fed her on the ramp and every bite or two i would scoonch it up a little with my foot until she had one,two,3,4 feet on the trailer it worked perfectly good luck and have fun
