Swack/Last Frontier Labs great points and others. As a self described "Health Dictator" due to witnessing and owning a few badly bred Lab dogs I would like to add another troubling issue. We have a closed registry and unless someone snuck in ringers before or during tattoo/microchip/DNA identification we have what we have. Do we throw out animals for breeding who have genetic issues? Do we do what others w/less available hard science did -spay/neuter or put down. Super Powder had one dysplastic hip but is a foundation sire. Super Tanker , Rascal have their issues. My two dogs which had dysplasia and retinal issues I spayed/neutered before sending them to non FT homes. They were never bred. I have no total answer but any who breed should remember you are contributing to the future stock.
