I've slowly been noticing Warren is giving her counter-training. He likes it when she stays on one of the chairs in the den when he eats and punishes her for getting off the chair, the very behavior I want her to do. He also thinks it's cute when she claws at his legs, which are mostly numbed due to the cyst in his brain.
He may be staying at his place for a few days. What can I do to either undo his training of her (he's home more than I am because I've got three jobs and he's got none), or (probably better) somehow get the dog to understand that "Master A wants X while Master B wants not-X?"
All suggestions are appreciated.
