My Mia was 2.5 lbs @ 13 wks. Now at just over 1 year she is hovering just under 6 lbs. Based on her weight she is heavy, but she is NOT fat at all. I've heard take the chart and then +/- 1 lb.
Somewhere on here is a list of her weekly weights for a LONG time. (I was obsessed with weighing her weekly)
Someone obsessed with a Yorkie????? Certainly NOT!!
