I think she is precious! My older yorkie, Hobbs, was 1.8 lbs when I got him at 8 weeks and he is barely breaking the 3 pound mark right now at 9 months old. I think that if she is willing to refund $500.00 if the pup gets over 4 lbs then you should go for it! Especially if you are already in love with her!

Oscar is going to have SO much fun with his new little sister!
