My boy is also a big one. He's almost 4 months and already 6,5 lbs. His parents are very small (around 4 - 4,5 lbs). For me it doesn't matter if he's small or big, i love him more and more every day. What i don't like is the people's attitude. They look, admire but seems very surprised when they hear that he's just a puppy and then starts to tell me that for sure it's not a pure breed and stuff like this. Even the vet told me the same things. But, this is the menthality here, what to do? They don't have too much experience but they act like they are the smartest and the best.
So, dear friends, what i think is the most important for us is our yorkies to be healthy and happy, even if they are small or big.
