inbreeding/linebreeding or open breeding/outcrossing???

This thread is kinda getting pulled in different directions with spins. I noticed there is a tendency to try and find a fool proof formula example brother x sister everytime works, Mother x son everytime works etc etc. Then another opinion that counters that one to the point that states line breeding is useless. There is no one way works for every dog or every breeding. Depends on the individuals being used. I suggested the method to Bo Pugh strictly based on the dogs he told me he had and what his plans were.

It has been shown repeatedly that dogs can pull from anywhere in their ancestry. That's why the one person saw plots from the same family produce different sized dogs. One guy breed on traits from certain individuals that were larger and the hunter bred on the more suitable working sized ancestors.

The formal definition of outcross is breeding unrelated dogs. So if you cross two breeds even if they share common characteristics that is not inbreeding. It is selection for certain traits but that breeding is an outcross. That is called breeding genotypically similar dogs and it does has it place but not as a complete replacement method. It still yields to the wide variety of genes you get from crossing different breeds So the breeder is subject to get everything under the sun that comes from "both" breeds. You may get the benefit of hybrid vigor the 1st generation (F1), but really what you did was take two inbred dogs from different families and breed them together.

Let me ask this question, if line breeding/inbreeding has no use how would anyone have a redbone to even cross with a walker? Redbones and walkers were developed through inbreeding. Every pure redbone is inbred off the same original family of dogs. Every pure bred dog is inbred. That is also how one would know how to put a finger on traits those breeds bring to the table. This is called uniformity and that's the value of linebreeding. I know people who have excellent working dogs that are purebred and the dogs reproduces themselves.

As stated selection is the key to any type of breeding practice. Selection for genotypic and phenotypic traits are useful tools as is outcrossing, linebreeding/inbreeding. All methods have their place.
