I have an 80lb brute of a pit bull that has broken out of a dozen crates or more. I had two play yards set up in the garage. The problem dog bent and broke the wire and collapsed it in on the smaller dog despite anchoring it in several places. This one is holding up to each test he throws at it. I did have to place a couple zip ties where two panels meet because he was able to push it outward some but I only did it to make sure it held over time. I'll likely get another one of these for the other dog as well.
