This crate is NOT escape proof.  If you get this, use zip ties in the corners on top.  If your dog is determined she will escape.  Also, if you have a dog with strong jaws, like a pittie, they will still eat the crate if they have high anxiety.  My dog bet the top and escaped within the first 10 minutes.  Next day, I used zip ties on the top.  She did not get out that way.  I let her out of crate within 10 minutes and have not tried again when she was biting the bars and bent them.  I did not want her to damage her teeth and mouth.  So be sure of the return policy if you are going to buy this item and you have an escape artist.
