if your dog stays in place while the kids do homework, he's not in their room chewing their toys. if your dog has a leash on and is in place he can't bite people at the door or the other dog in the room, because you have a hand on the leash to give him a correction if he breaks command. (yep, you need to be correcting your dog with a leash pop for breaking place).
when you start making better choices by teaching your dog how to sit still and tune in, your dog will not be making repeated mistakes and in fact learning a new way to live with
