I have a problem that I've not heard of anyone else having or have seen any training suggestions for.
My mare does not like to be in a confined spot in the trailer or trailering alone. She needs to be in the back where she has leg room. She is very calm when trailering with other horses but very nerveous alone... She does not hesitate to get in or out but to stay standing quietly by her self in the trailer alone. Once the doors start to close on her she gets very nerveous. Any suggestions would be appreciated.
