Personally, I think the dog/dogs being bred to one another or back into a key dog are just as important. I get guys talking about doubling up or inbreeding dogs all the time not considering the weaknesses of the animals of emphasis. I think dogs of emphasis should be special dogs. Dogs of excellence. Not dogs of a blood.

I have an excellent male right now who is special. It's apparent, his special traites and qualities are from his grandmother b/c every dog I have that has her in their 3rd or closer, act like him (more specifically HER). So, it's obvious, I need to breed him back to her on her next heat. However, if HE himself weren't special, why breed him back to where that specialness comes from? I don't think it should be done. End up going through a lot of questions with the offspring. I plan to take this special dog, who has same traits as he special grandmother and then inbred a male and female off of that back to both of them. I will also make my selections based on dogs that exhibit the exact same traits that make both of these dogs special. I will not randomly choose one b/c it's out of that litter. Confirmation, intelligence, traits, etc. should all be considered.
