I think you are feeling normal frustrations but you are figuring it out. Perhaps you were just venting here, maybe looking for some advise, and reassurance. We have all been through they puppy thing (or are still going thru it) It can be very trying at times but someday you'll look into her sweet little eyes and say I remember when you were such a little sheet!
I don't think you will give up on her, thats why you posted here!
