I do hope there is a legal solution to this problem. Those people don't deserve the benefit of the doubt. They had you running around in circles for too long. In the mean time, it's poor baby Cooper who has to adjust to new situations. Who knows by now if anything they have told you is the true. They may be counting on the fact that you will not drive four hours (of course they don't know you) to meet with the trainer, if there is a trainer in the picture.
Good luck in your search for a good lawyer.
