Colour me unimpressed

This is the view from inside the kennel block, all nice, neat, tidy, several K9's lounging around waiting for yours truly to feed/take them walking/let them on the sofa. A picture of tranquil harmony. I am very pleased with my handiwork, its not finished yet but a week away from paid work is planned very soon and that should see it ticked off the jobs list. That was until Bliss, who, being in season was left shut in a kennel behind steel bars while the boys had free reign of the house and several of the girls were out on the hill with me. Bliss took exception to this so bit the bars. All of them down one side and then the other, and having bit all the bars she set about bending them, and unbelievably biting and bending two of them off allowing her to get in the next door kennel and out through the open door to join in the fun and frolics on the hill. Any ideas on how to deal with a dog who can bite through galvanised steel bars, apart from carefully,  will be greatly appreciated.
