Bought this for our dog and started off great day one.  After that he figured out every area possible to get put of it.  Opened zipper on front and top.  Had to tie zipper together but then he clawed at the canvas area and broke the front.  I stopped using it for him and my daughter tried it for her golden retriever puppy. He destroyed it all together!
Who knows maybe it's great for some dogs but not for our two. Certainly not safe to leave them unattended in it which is kind of the point of crating them.

Pros: Great for travel. Folds down easily
Cons: Dogs quickly destroyed or escaped it
