This cage suits my needs. My adult dogs dont try to escape. I use them to separate my 3 females who will fight each other. I have recently discovered that my male dog is smart enough to open the cage from the outside and release my females... the cage was empty of females... he was actually going after the food that one of them had left behind. None the less, it made me aware that the double latch design is too simple. To be fair... he would not be able to open the latch from the inside of the cage. I have a cage (unknown mfg.) that I purchased some twenty years ago and still use... it also has a double latch, but they are connected by a double vertical rod that is spring loaded... it is more of a pain for me to open and lock but it is relatively dog proof.
