His parents were just their family pets. We don't have papers on him and I don't care at all. If you don't plan on showing or breeding, what difference does it make?
It only makes a difference if you're looking to hedge your bets (some folks aren't, and that's cool). Personally, I want a dog of the breed I enjoy, that epitomizes what I love about the breed and will bring me joy for as long as possible as my dogs are members of my family and a commitment to them is a lifetime commitment. A few hundred extra dollars up front to avoid preventable genetic disorders or temperament issues is money well spent for me, and heartache prevented - over the course of a 12 year life, hardly much money at all.
Strangely, pet store pups cost MORE than well bred pups most of the time, but the stores prey on people who are making spur of the moment decisions. And while the folks here who have bonded with their pets are no doubt providing great homes, the 21 year old college student sharing a house with 5 friends who buys that cute puppy on a $20/month installment plan, with no foresight as to who will take it home next summer, or who will be responsible for the $1200 vet bill when it swallows a sock... the pet stores don't care about the puppy that falls into THOSE hands.
And those puppies don't tend to stay in their original homes very long. They end up passed from home to home, in shelters and/or if they're lucky, rescue, and at that point you can get a great dog without enriching those who are making money off the backs of the dogs.
Most rescue dogs are NOT damaged goods -- just somewhat neglected goods. Typically in my breed (boxers) they're 7-8 month old males who aren't quite as cute any more. The people who bought them were suckered by a pair of soft brown eyes, and laughed as the pup climbed and jumped on them and bit their shoelaces... but behaviors that are adorable at 15 lbs are less attractive at 50 lbs. Suddenly they have an adolescent dog on their hands that has never been taught any manners, and they blame the dog. Sadly, many go right out and get that next dog (probably a different breed), fail to teach it any better, and repeat the cycle.
Of the rescue dogs I've dealt with, a basic obedience I class is enough to make them into good citizens -- they're friendly and cute enough, just underexercised and were never taught basic manners. Rescue foster homes will begin teaching basic house manners. Mostly the dogs need the guidance that their first owners were too busy or ignorant to provide.
