Thread: Are Labradors good at finding Large Game?

It is only when the fault carrying animal is back crossed with another animal carrying the same fault that it will possibly make its appearance once more . Crossbreds are more vigorous, healthy, fertile and have longer lives than the parent breeds from which they are derived, this is on average measured at 16% in the first or F1 cross.
Genetic progress in breeding is best made with pure breeds. It is possible to use cross breeds to form new breeds but needs a lot of resources.
In summary, the parents of pure breds need to be totally 'sound' and free of genetic faults ( not just physically tested to not have the fault because they can still carry it ), whereas for a utility dog that won't be bred from a crossbred is a better bet if the genetic soundness of the parents isn't tested and proven.

If anyone is interested, I know where there is a Lab male that leaves exceptional pups. He totally 'stamps' his litters and every pup is brilliant and improved. Pm me and I can put you in contact with the owner.

You make some good points. It still identifies however that cross breeding is not a magic cure. The issues still remain and they are still being bred forward into the next generation. Crossbred or purebred, the responsibility for health checks and responsible breeding remains the same.
