training vs. natural instinct

I think your rite, I have 4, year old dogs that just go on their own, will find a hog, bay good... no training, its amazing, and most of my older dogs were that way as well, it just came natural, some have to be trained, i dont really waste the time on one anymore once i give it time to see it dont come natural to it, its gonna start some talkin, but im gonna go ahead and say it... If you breed proven dogs from proven lines it will pay off, not on every pup, but if its bred into them then they are alot more likely to just pick it up on their own. And just because you have two good dogs and breed them, that dont make a good set of pups, what if they were the only two good dogs out of either of their background? It takes years of dedication to raise an entire line of proven dogs to get to where you can start throwing good percentages of naturally talented pups consistently
