We've already seen a canine AT-AT costume before, but that one didn't involve PAINTING AND GLUING THINGS to a dog. Oh man, remember on Hoth when Luke used the tow-cable from his snowspeeder to bring that one AT-AT down? Well this one's gonna run away from home.

Thanks to Patrick J.M., who went to CanineCon last year and said there was kinda dogs dressed up like shit.
