So I started looking at trailers to try and get ideas of what I need. One person showing us Hawk trailers suggested that I should be looking for a 6' wide for my TB because as she put it, horses like to feel snug and secure in there particularly around corners. I'm confused by this since all I ever hear is that horses are claustrophic and hate tight spaces. My horse has no trailer issues. He'll load himself as long as there's a bag of hay in there. Does anyone agree or disagree with this statement for any particular reason?
