My parents got a lab about 3 years ago from buy and sell - you have to know what you're looking for and what you're talking about if you are going down this route in order to make sure it's not a puppy farm so if you don't know about dogs don't go to the buy and sell. As it so happened this was a registered breeder so there was no problem and dog was fit as a fiddle. Make sure no matter where you get the dog that you see it's parents first - any good breeder will have no problem with this - make sure you get the parents names/line and all papers associated with the dog. Labs are very prone to hip problems so look out for this in the parents as they walk around. I would recommend two avenues for you, go onto the IKC website and look up Lab breeders in your area, there will be loads and they are registered proper breeders. Or as previously stated would you consider getting a lab from the pound - they always have a lot of 1 year plus labradors in the pound because people buy them as 'Andrex' puppies and then when they grow up they throw them out - Your parents are going for the right type of dog - labs are amazing dogs, great fun, very loving and very gentle - although do please watch out for the hips and also weight gain - they can get fat quickly!. Best of luck
