Hello my name is Liz im new to this site and will be new to a yorkie... Never had one but am excited. Just wanted to say Hello and hope to get to know all of you. I just wanna ask you guys how hard is a yorkie to house train? Any tips or things i need to know? Do u prefer boy or girl and is there a reason why? I want a girl to doll her up. Is there a difference in a silky and yorkie or are they the same ? Also is there a way to tell color they will be i love the color they have as pups and the scruffy looking pup hair..... By experince a 4 week old pup at 1lb now may weigh what as adult? alot of questions im curious, excited and nervous
