I'm not sure board-and-train would be a good option for this, as the integral part is teaching YOU how to handle the dog. If the trainer works out any kinks in a kennel environment, it seems likely that once the environment is reverted back to the start, with the same variables (including you, and your daughter), your dog may revert as well. I would think finding a trainer who can come into your home and observe everyone's interactions with the dogs and show you how to build on your day-to-day routine for better management would be a better bet.
