I made this dog box out of 2x4 and 1/2 inch plywood. It's kinda overkill but it's what I had to work with. Made it with divider inside for the simple reason that they are handy at times. Put two eye bolts on top for rigging. Had it sprayed with super liner from three way auto body. I wanted a finished look and something for the dogs to grip on top. Turned out well I'm pleased.
<br />Had to have my bother get inside to tighten the eye bolts because I made the doors to small for me to fit in.<br />
