HIS NAME
Teaching a puppy his name is a good way to begin training. As soon as you get your Lab home, start repeating his name, and very soon he'll get the message. Use his name every time you call him, and make sure to add it to all your commands. ("Stay, Goldie." "Sit, Goldie.") Don't use nicknames or variations of his name until you're certain he knows his name. Remember to praise him each time he responds to his name.
COMING WHEN CALLED
"Recall" (coming when he's called) is a fundamental puppy skill, and is next on your agenda. The puppy comes to you never the other way around. He'll thinks this is a game at first, and may run away or hide. Don't follow him. Repeat the recall command "Come, Goldie" until he understands. Pups have short attention spans; so keep your practice sessions short and frequent.

Labs are prone to hip dysplasia, a malformation of the hip joint that ranges from mild to severe and can cause such disability or pain that major surgery is necessary.
Dysplastic dogs usually become arthritic.
Labs are also prone to several eye disorders, including progressive retinal atrophy and cataracts, and epilepsy.
Purchasing a healthy Lab pup can be a bit difficult, but the research to find just the right breeder and puppy is well worth the trouble.
