My dog busted out of the seams of her last crate, so having doors that would lock well was essential. With this crate, on the longer side with two doors, she would easily be able to push the two doors apart at the bottom where there was no locking mechanism. I added 6 additional locks at the top and bottom of each door to ensure she did not push her way through, and potentially seriously get hurt if her head were to get stuck. Other than the doors securing completely, it is a very nice crate and she has had no issues with my extra locks added.
