1year old Setter/Lab Mix

Question
My 1yr. old Setter/Lab mix is a big girl, and I was wondering, could you give me an estimated size that she could be, and/or, when will she start growing more out than up?

Answer
She should be her final adult size.  Most likely her growth has slowed down.  It may continue, but very slowly.  Even if carefully kept lean, she should broaden out, a change of shape, not becoming bigger.  You may find this interesting, http://jn.nutrition.org/cgi/content/full/134/8/2027S

Your dog definitely should be narrower at the waist than the hips and chest. You should be able to easily feel the ribs, but not see them. Each dog is different. Standard recommendations are a good place to start, but each dog must have its food and exercise adjusted to its individual needs.
