Bingo. Same situation in terms of a too-smart dog that isn’t motivated by food, treats, toys, or much of anything else.
My rescue was abused as a puppy, and anxious around strangers (we assume as a result). He’s improved tremendously in the 6 years since we got him, but there is no amount of training that will ever make him truly comfortable with strangers. Especially strangers without dogs, coming into his home.
