ok, I padded the escape door down where it opens. My trailer has very good padding on the center divider and on the wall. He is scraping his knee on the lower part of it, and down the left front. He is also stepping on his feet with the other foot. Only on the front hooves. That is why I wonder if he is not able to spread his feet far enough in the front when I turn. Several of us have looked and felt the side and all we come up with is hitting the lower part of escape door. Because when I padded it and put leggings on him no more scrapes. Just worried that trailer is to small. Does anyone think a slant would be roomier.
