Well, for potty training, I suggest puppy pads for a little bit, maybe near the spot where Lucky has an accident the most?? Then when Lucky gets accustomed to that, begin to take him outside and wait patiently. He won't want to go outside at first to go to the bathroom but he'll eventually learn that's where you want him to go.
And get lots of chew toys. Puppies are going to teeth, so they need plenty of things to chew on that you guys will approve of. And when Lucky tries to teeth on your hand, snatch your hand away and tell him no, so that you can teach him that your hand is not an okay thing to chew on.
