And that's where you and I are different, as I'm sure we all are in regards to some ways. I would take plenty of dogs off Taz. That doesn't mean I would breed them when I'm finished. I look at breeding dogs as a complete thing, not a 50% thing. I've owned dogs off Little John, and even my own dog, that I never had the intentions of breeding. I can think of quite a few examples of dogs such as you describe, that when bred, produced dick. They couldn't reproduce the gameness they showed. Possibly it could be they just weren't producers, but to a T of the dogs I'm thinking of, they were always 1/4 or 1/2 bred from something not noted for that gameness and/or produced it on such a rare basis I never wanted to feed it again.
So, I agree in taking a dog off Taz and doing whatever with. Just as I would take anything off Frosty, at this point, or Little John. But that's not a guarantee to be bred and carry in the program simply because of that.
