Hi there, I am a newbie to yorkie talk

I have a six year old female yorkie and have decided to get another. (yay) I was wondering if any of you had some advice for me? I hope it's good for her and it doesn't change her personality at all i am a bit concerned about that. Her personality is very sweet, loves people, loves to play, very cuddly and totally attached to me more then anyone in the house lol please give me any advice possible

Thank you so much
