Jim Dandy: Does what apply?? lol....if you mean the good breeding...WHY breed a purebred dog if you are breeding flaws?? I would go with a mut if you want a companion..they are wonderful dogs...for a good strong dog tho,a purebred should be sound mind and body.And I don;t have show dogs,I have working line GSD's there is a difference,lol....I love the working line...not much into the show line.
