I always thought it would be "cute" to have a real little one.  Mine are :
Rocky 6lbs @ 6years,  Romeo 6.5lbs @ 13months and Rosie 7lbs @ almost 2!
Now I have my newest baby, Raindrop who is 1.8lbs at 4months old.  To be honest, it's a little scary having one so small.  I am always afraid the others will run right over her, and possibly hurt her.  She (Raindrop) thinks she is a big dog, and runs after the others. I do keep her in the playpen when I go out, while the others have the run of the house, and can use the doggie-door.  So to me, the people that want a tiny Yorkie are not really thinking of what they might have to go through.   Of course if Raindrop remains small, then she does.  I will just have to really watch out for her with the other dogs, and people that may come in my house.  I sure don't want her to get stepped on.  So size is just a number.  What will be, will be.
