Your little one is just precious!
We have a younger yorkie too and we have two different set ups. We have one in the family room where we stay most of the time and one in our bedroom where at bedtime she feels safe and sleeps.The way we have them set up really can help with this age sooo much. Our little girl also gets a bath every week keeps her smelling clean. She used to have problems with her bathroom times too.She would get it stuck on her somewhere and ohhhh what a mess she thought something had her and she would run to get it off and hide. Yes by the time I realized what had happened it was all over the place. So we have been there done that too. Oh fun
but they do get through this stage pretty quick our little girl is doing much better. She now goes and sits in the nearest corner very quite so I can tell she's been busy but its not all over her any longer. Each one does so different she's my first that has acted like this out of 6 yorkies.
