Safety
Check the hook-up to be sure it is stable and secure. Does your used horse trailers appear rusty or loose? If so, call the owner or drivers attention to this area and ask if it can be double-checked. While youre at it, see if the doors close snugly and can be bolted adequately to contain a horse that may become distrait in an enclosed space. Inspect the door latch and lock to ensure that it is strong and in good condition. Also, examine any windows in the trailer to see if they can open, or will be open, during the trip. Some horses seem to enjoy the fresh air, while others dont, so you will be the best judge of your horses preference.
