Shelby & Seymour are both 7+ lbs. They are a little over 8! Shelby has lost a little weight now so she is about 8# 2 oz. (they are a few ounces overweight still and probably would be ideal at a little over 7#.
There are lots of bigger Yorkies here on Yorkietalk.... and you are right..... we are lucky to have each and every one.
