"I would not purchase a tent style crate again, especially this brand. Both of my crate trained dogs learned how to break out within a few days. We bought these to travel in our motorhome with since they are so easily collapsible and lightweight. We came back one morning to see that they had broken out and damaged the carpet in the brand new motorhome. They discovered that they could push on the front of the crate and split apart the zipper.
We have not been able to replace them yet with a wire crate, and in the meantime the male chewed a hole in the corner of the crate and pushed through the front, so it's now destroyed. This is the same dog that we could leave in his crate at home with the door unlatched (inadvertantly) and come home to find him sound asleep, still in his crate.
I had read reviews before I purchased this and did have concerns about them breaking out, but I decided to take a chance since they are already crate trained. Don't make the same mistake!"
