Welcome to YT and congrats on your new baby. Hyper, crazy baby, lol, yep, typical yorkie pup. Yorkies are very hyper pups, bursting with high energy. The biting you need to correct NOW, she bites, you say in FIRM voice NO BITING and give her a toy she can bite. This must be consistent command from everyone in your family. She is only a baby, it is up to you and your family to train proper behavior. You must be patient, and CONSISTENT. As for pad training as yavenay suggested, she MUST be confined to a small area where her pad is. When you let her out she MUST be supervised. If she pees or poops somewhere other then her pad, take her pad, place it on the pee so it will absorb the pee, put the pad back where it belongs, pick her up, place her on that pad and tell her pee pee on the pad (or what ever word to use for pee). when she poops off the pad, pick up the poop, place it on the pad, pick her up, place HER on the pad and tell her poo poo on the pad, again this must be CONSISTENT, she is just an 11 week old puppy, getting them to be 100% pad trained can take up to them be 5 months old. You MUST have patience and be CONSISTENT with pad training.
Barking lol, yorkies are known barkers, if a fly flies over Alaska they can hear it lol, and will bark. When she barks FIRMLY tell her no barking, no yelling, no shouting, just use a firm voice. A barking puppy is normal. remember, LIFE is all new to her, sights, smells, noise, all new in this big world . Good luck.
