oh wow, that sounds eerily familiar! mine spent the first 2+ months having anxiety diarrhea at 3 in the morning, worried that i would hit her for breaking some impossible to discern and arbitrary human rule.
i actually detrained my dog from walking on the left behind me because it otherwise reinforced anxiety, low self-esteem, and a strict dominance relationship, which just made me sad (and her too, i'm sure). i now let her walk freely to engender self-confidence as well as a measure of independence. she's still very obedient so will take direction quite willingly (sometimes getting anxious even now when she can't figure out what i want, though much less frequently).
