You know, many people have payed quite a lot of money to get a healthy puppy? Not physically only, but mentally as well? Anything could be corrected in the plasticine dog: you socialize him - he would be a family dog, you train him in a Schutz club - you have euphoria known to sportsmen, you want him to protect your home - no doubt, he will learn how to do it properly. But, will you fail to have a perfect companion or not depends on his health. That is all what pedigrees are about: dog shows confirm trhe statue and medical condition, and Schutz competitions confirm mental health and intelligence level. Ideally your pup should have parents with a degree in both.
