What size black lab?

Question
Hi, we have a 9 month old black labrador and are concerned about it's size. What average size should a 9 month old black lab be? Thanks

Answer
He should be approaching his adult size, maybe about 60 pounds.  Keeping a dog lean and an early switch to adult chow delays reaching adult size giving more time to develop sturdy joints, see http://www.puppychow.com/products/popup_body_condition.aspx
