1. Defects. The number one most important reason genetics are important when searching for your new puppy is to prevent structural hereditary defects (hip dysplasia etc). For this reason, we have outstanding organizations like OFA that you see on so many pedigrees. This organization and many other's strive to breed out health defects.
2. Obedience. Believe it or not, genetics play a huge role in a dogs obedience. Through selective breeding (or genetic manipulation), breeders can influence dog behavior. We can enhance obedience, reduce aggression etc. Genetic obedience is the willingness of the dog to by instinct to obey his handler. This dog not only wants to work but wants to work in cooperation with his handler. He will do his task willingly, reliably, and independently. Let's take a dog with the MH title for example. Do you know to receive that title they have to demonstrate the utter most obedience in addition to their hunting requirements? The handler can't even use their voice very much! The dog must instantly obey. This is why they are truly a "finished" dog. As a breeder, I would NEVER chose a pup with the intent of it being a MH that doesn't come from a PROVEN hunting line. That would be just stupid! If you're looking for a hunting companion, chose a line with MANY proven hunting dogs!
3. THE NOSE! Do you know you can buy a GSP who is bird dog stupid? Just because you bought a GSP with the expectations of the dog being a hunter, doesn't mean he will be. What is in his genetics for hunting? Are his ancestors proven hunters by NAVHDA or AKC trials? The NOSE can be breed out of the breed. Don't make this mistake. If you looking for a hunting companion, only go with a pup who's pedigree is full of hunting champion ancestors!
4. Aggression and temperament. Did you know the #1 cause of aggression is genetics? Selection is the #1 means of preventing aggression. Know the line you're buying. What are the sire and dam like? Do they fight with other dogs? Socialization and exposing the puppy to new experiences are important also. Take your pup to the park! Let the kids pet him. Let him be around other animals.
