The other aspect of inbreeding a very tight family that few understand is making a "cross within the family" not based on pedigree or inbreeding coefficient, but rather on traits. I use every trait I can identify to determine where the genetic influence is coming from; from coat color, down to whether they shit in the same spot or not. Being "too inbred" on paper does nothing to sway me away from a breeding, but seeing the wrong combination of traits in the prospective parents sure might. I am quite certain when I mention my dogs with a 75% inbreeding coefficient, many people think I breed too tight. Even though we have perpetuated these same dogs in an unbroken chain since 1990, having shown, tested, and evaluated every aspect of these dogs, someone looking at a pedigree may still be audacious enough to make a judgment. I can produce dogs with 93 to 99% inbreeding coefficients, but selection for the right traits is everything! Meanwhile, the critics of my breeding practices would take 25 years of experience and effort, and blow it into pieces with a single outcross. No thanks!
