My dog is VERY smart and an escape artist! So I cut a piece of plywood, drilled holes around the edge and secured it under the tarp top.  The product itself is resolvable sturdy and a super idea.  But my midsized dog will love the space inside her pin/kennel, and will be able to be outside, partially out of the elements. (I put think under my back porch.  Then I added a heavy object on top of the wooden top, under the tarp.  She is quite strong and can chew through a lot of materials.  Now that I have the pin anchored between a few items, on concrete and with a heavy bird bath bottom to one side attached ... I think I will be able to be at peace when I have to go out.... she won’t be getting out and getting run over. Love my fur baby!
