And this will ruffle a few feathers I'm sure. But if you are having to breed your dogs to something else for this or that, was your dogs even that good to begin with, probably not. A hog dog doesn't need this or that, it needs a ride to the woods is all. I can ask that cuz I raise, feed, and hunt plenty of culls myself.
If this is true then all I got to say is man there is a lot of us that are just breeding pure Chit then. I been a breeder of dogs a long long time and I aint never seen a line of dogs so good that they could stand on their on for years and years of heavy line and inbreedings. Without needing this are that and yes a cross to something to bring back out what they once had because they aint gonna get it from the family any more because there is no room for the gene pool to breath because it is so stagnated. A line can only take so much and then go stagnant with its on gene pool !
