We've had our Yorkie puppy just over 2 weeks now. When we first got her she was very quiet and reserved. Like the other posters said, we loved on her lots and kept disruptions (visitors, etc.) to a minimum. She is a holy terror now!
Telling our 5 year old mini schnauzer what to do and bending the humans in the house to her will (the head tilt gets us every time
).
She spends her days (when we're not home) in an ex pen connected to a wire crate with an area for food/water and a puppy pad down. Our girl is 16 weeks old but that's still too little to go through an entire night without pottying. We have a second crate in the bedroom where she spends the night. She wakes us once usually for a potty break. We tried leaving her in her ex-pen crate overnight her first night and she was beside herself- 8 hours of barking & crying!
The breeder told us she was used to being near people at night and to try having her sleep in a crate in our bedroom. That was the ticket! Being able to see and hear us was very comforting to her and she sleeps there happily without complaint every night.
Congrats and good luck!
