Why do you not like cages and say you will not use them?
I would have thought they would be the ideal solution to your problem as you can then prevent the destructive behaviour instantly and control the dogs while you get the coats down, and if you are only going to take the kids to school they would be ok left for that short while. Even if you are taking the dogs out, you could get ready while they are in the cages, and then get them out one at a time and put their leads on.
The problem is you are not there to do anything about it, so you are in a way letting the dogs think it is ok to do.
