Many many reputable breeders do put breeding endorsements on the pups registrations. this gives them some control over where their line is taken. Most will remove them only once you have had all the health tests with acceptable results, the pup proves a good enough specimen to breed from, and the owners shows a genuine long term interest in the breeds and any future pups welfare.

Pups without endorsements can be bred from and the progeny registered, even puppy farmed.

With a breed as widely bred and also exploited as the Labrador, good breeders will wish to ensure their pups only contribute to the production of quality responsibly bred litters.
