Can you reinforce the crate with zip ties? Or put the crate in a separate room and close the door?
My Basu did the same thing. Bent the bars and bent his teeth too.

No.Originally Posted By: TheAlamoGangMy Senior is starting to go down hill and I know he won't be around too much longer, so I decided on a rescue instead of a pup to keep my 3 year old company. I found a beautiful, sweet and fairly submissive male ~2 years old. Last night when I brought him home, all the boys played well together. But this morning he was playing with the 3 year old and got too rough and my 3 year old growled to let him know that was not OK. Then the rescue growled back and they did the stare down while growling and my old guy takes off to mediate. I called all 3 of them down before anybody thought about fighting. I had intended on crating the new dog when not supervised until I was sure everyone had accepted one another.
Imagine my surprise when I came home at lunch to let the rescue out and I see 3 GSDs coming out of the house through the dog door!!! It also scared me to death since they had done a little posturing with one another this morning! I came in the house and the rescue had bent the bottom of the crate up about 4 inches and he must have crawled out sideways. (He is very thin at present, but full grown none the less.) It still amazes me. That crate has contained 4 GSDs and a Doberman in the past.
My suspicion is that as he was wiggling out, my other 2 must have scared him a little as I'm sure that they got excited with him struggling. He is not challenging them at all now and taking the back-seat, so I'm not sure what happened that took the wind out of his sails. I checked everyone over and no one appears injured. They actually seem pretty calm and settled with one another. The problem is that I live in a very small town and I have no way of getting a super heavy crate until at least Thursday. Do I dare leave them together unsupervised? (I had to take my chances after lunch because had to get back to work.) Any thoughts or ideas would be appreciated. I have always raised my dogs from pups and this is my first attempt at integrating an adult into a pack. My only options at present are to return him to the rescue (she has a kennel) until I can get another crate or pray they have truly settled the pack order and just leave them together.
