We are moving to a new home on 40 acres and need to build a new kennel building and want to do it right. We made a few mistakes on our last kennel. One of the big mistakes we made with our present kennel building is just not enough natural light. Electricity bills are high because we have lights on most of the time. If you have any ideas to share, I would like your input on what to do and what not to do. Things that you are very happy doing, things you wish you had done, or things you have seen in other kennels. Also can't remember recommended slope to the drains.
