Edit so I can hopefully make the spirit of my own complaint more clear: my puppy is defiant and stubborn and clever and a big doofus. Rules are a living document and they get revised all the time. If I communicate them and my expectations we grow together and move on to the next misunderstanding with some grace and patience. If I just decide that the rules change without saying what they are, I’m setting my pup up for failure and myself up for her resentment and an inclination to impose more strictness that she won’t understand.
