My little yorkie is going to turn a year old on March 28. She weighs in at a respectable 4.5lbs. I'm thinking she is at her full weight. Do you think she willdo any more growing? I would love to see her even get to 5lbs. I also have a yorkie-poo and a chocolate lab and they love to play together. If she got just a little bit bigger I wouldn't worry about her so much. :
