Well, your puppy looks darling! Probably less darling when he is mercilessly mouthing, though.
From what you've said, I very much doubt you've traumatized your pup. Yelling and/or stomping on the ground could actually be an effective correction, though of course you don't want to do it in an out of control way. In any case, no one is perfect. You are doing your best. Take a deep breath and go take it out on your husband!
