I have three of them two night boxes that are 4'x4' that is used at night and also a 10'Lx6'Hx4'wide with mesh siding to allow sun light in deck flooring spaced just enuff so the dogs feet dont slip thru! Then we put tarp over it that we roll up in the summer to let the breeze in and drop it down over the winter to keep out that cold winter air. They do get wedded feet if u would but a daily walk or allowed to run a chain a few hours a day helps with that! Tell u this the one who is kept in the 10'x6'x4' is much more healthier and less baths and if i forget about a worming no real worries.easy to clean and he loves it just as much just u will need to get them.
