puppy size

Question
We just purchased a 8 week old lab and are concerned with what his actual size may be. We have a lab now that is 90lbs and are looking for another large labrador. How big should a puppies paws be at 8 weeks? Is there any other way to tell?
Thanks

Answer
I really have no idea of any way to tell.  I have had a number of puppies that everybody talked abut how big they would be because of heir paws and they turned out to be runts.  

You should be feeding a puppy chow now. Switching to an adult chow for the larger breeds at 4 months, slows growth and helps develop sturdier joints.

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.
