Hi, Congrats on your baby. I have an almost 7 month old Yorkie. He did all the same things, it can be frustrating. You have to keep a vigilant eye on them at all times. I used to calm him down in a few ways. I would put him in the kitchen that was gated off, never in his crate. Sometimes turn my back. I also gave him all natural "mellow mutt" chicken breast treats with lavender which have calming effects. As far as biting always say ah, ah, ah, "No Bite" in a firm loud voice. He'll eventually get it. Same goes for barking. Never allow them to bark at people. Even coming to your door. Get her around as many people and dogs as possible. My dog loves people and dogs and doesn't bark much and if he does hel barks a couple of time as to tell us someone is coming. GOOD LUCK! Be Consistent!
