Emmett,
Because of the fact that my Husky/Chow escaped from what I deemed to be a *very* secure metal dog kennel, I'm not going to use your suggestion. If he could get out of one that easily, I am pretty sure he could also break into one. I'm certain that for people who have smaller dogs (under 50#) or animals with a smaller drive toward prey, this would be an excellent solution!
Thanks for the idea.
