Please Note: I did not include a list of breeders here. Since Labradors are the #1 most popualr breed in America (with yellows being the most popular color) I considered myself unqualified to make any sort of recomendation whatsoever regarding breeders. I will include what you should look for in a breeder as soon as it is finished.
Lab Resources:
General Information
Labrador Net (superb) - an excelent resource for Labradors, the best I've ever found.
Field and Hunting
Ask the Trainer - a FAQ source for field-training your dog. Very extensive
On Silver Labs:

The Breeders
