Well, my Livvi (in my avatar!) is a little prissy girli girl, who is also very stubborn and the boss of the boys! HAHAH! She is a bit more laid back, and definately has a big attitude! HAHAH! My boys who are yorkies, are sooo lovey dovie! They love to cuddle! Livvi is more of my loner! She doesn't like to cuddle as much! But she is soooo sweet and sooooo good! So, honestly, I don't know if its a biewer/yorkie thing, or a girl/boy thing? I have had the honor to see many of them in person, and let me tell you, when you see them in real life, pictures don;t do them justice!!!!!!
Here is another link for biewers!
