Chloe is 2.5 lbs @ 8 months old. I don't see her getting much bigger.
She is sooooo not delicate. She jumps from the sofa if given a chance , runs like the wind ( well, a small breeze atleast

) and gets rolled on by Sydney ( our 10 lb. non Yorkie doggie ) and has to outwit two teenagers and an 11 year old that always want to hold her....nothing seems to stop her.
