One of mine (Jake) is 20lbs--more to love--He too was 3lbs at 8 weeks. It's nice to find another YT member with such a big furbaby. No one around here beleive he is a yorkie. I also have Maya who was 3lbs at 12 weeks and is 8lbs now. Her dad was 2lbs goes to show what that means lol. And then my littlest guy was about 1.8 at 12 weeks and at 8 months is almost 6lbs. Hey maybe next furbaby will be 4lbs I seem to be on a roll lol. They are additive aren't they?
