Dog Run 4x4x1.83m
This is a pretty strong and easy to assemble run, tho it took us a bit longer than 1 hour to put it together (not being trades people). Suggest you get something to anchor it into the ground as our big dog is able to push it along.
Pretty easy to assemble, I put some self tapping screws into the latch and hinges to stop them rotating when our dog tried to escape, which he did. Seems to have sorted it.
