Very easy to put together, maybe 5 min. Much cheaper at Wal-mart than pet shops at almost twice the price. Although a bit expensive for 5 pcs. of blow molded plastic. Very light weight.
Our Aust. Shep. fits right in, but was scared of the slick floor and how it slid around on the cement patio. I popped the plug on the bottom and filled it with a couple of bags of white sandbox sand, stays put now.
The box it arrived in was destroyed but everything was there and OK.
This unit is for a Med. size dog, Not a Large dog like the text says.
