Here are a couple of thoughts on that new Lab. I am on my third Lab right now and have some experience with the breed. First of all I am no expert on this, but here are a few ideas. The breed has been inbred to some degree and some breeders put profit ahead of quality. I have a male right now that is going on two. I got this dog for free, from a third party, at 10 weeks old because the breeder discovered this dog had a heart murmur and was going to put the dog down. This is a great looking dog, you just know he came from some good lines. The breeder didn't want anyone to know where the dog came from so that is why the use of a third party. In the past this breeder just put the puppies down so no one would know that his line threw puppies with heart murmurs. This dog also had genetic elbow dysplasia in addition to the heart murmur. I knew this going in and decided to take the dog anyway. I am not much for blaming others for problems. The point I am trying to make is that some of these breeders would rather put the puppies down than stop breeding the parents. Make sure you get some form of guarantee from the breeder. Most of these breeders will replace the dog, I would ask them to replace the dog plus 25% of the purchase price if the dog has any genetic problems. If they get reluctant about a monetary guarantee, this would be a red flag to me. Make sure to get the OFA reports on the parent's hips and elbows. The dog I have now has turned out to be my best Lab so far after about 4k of medical treatments. He hunts twice a month. He still won't live much beyond 5 years according to the vet, due to his heart murmur. He is a wonderful dog and I think Labs are super dogs! Good Luck with finding a great dog.
