Some pups are just born nervous and aint shit you can do about it.
The only reason that some folks might say that a bitch is always more important is because of mitochondrial DNA. They get none of that from their daddy cause it maternally inherited for the most part. There are only at the most like 1000 molecules of mtDNA in sperm but something like a 1,000,000 in an egg and also I believe that the "fetus" or whatever you call it in a dog (HAHA) absorbs some mtDNA also through the amniotic fluid. Nuclear DNA is the 50/50 deal and there is no disputing that. There ya go, thats it. But
