Alright, so if luck and finances are on my side within the next few weeks, I will (hopefully) become the owner of a little quarter horse/percheron mare, who is 14.3hh and a very sweet, gentle girl. She's very well behaved and has flawless ground-manners, however the owner recently informed me that she can get very anxious when entering a trailer by herself, and this has led to a stressed colic, once before. Transporting her from her current residence to ours would probably be a 15-25 minute drive, and would be on the highway majority of the time. Any pointers as to how I could prevent her getting so worked up?
The owner said that she trailers fine when she's with another horse, so if it's safest, I may rent a two-horse trailer and kidnap a friend of mine's horse for a day, to help out. But, I have no idea if that is even an option. Any pointers?
