Hi guest. Before you even think about using him at stud he will have needed to have his hips x-rayed and scored under KC/BVA scheme (which is done after the dog is 12 months old), and pass the various tests for hereditary eye disease (after all, you don't want to find yourself in court because his puppies had health problems that could have been avoided). I suggest you buy a few good books about labradors, and carefully study the Breed Standard to find out what are his good points and his faults (no dog, even the top winner, is perfect, although we all like to think they are!). It appears from the wording of your post that you are a newcomer to labradors ...
Good luck.
