As for genetic and health testing, luck has something to do with it. I've been both lucky and unlucky with the health of my dogs, the first one having to be retired at age 6 due to severe elbow dysplasia. With my last two I've settled on nothing less than all the tests being done on both parents. You can still end up with an unhealthy dog no matter how healthy the parents are, but I like the reassurance of buying better odds. I also wouldn't buy a puppy if the parents were untitled in hunt tests and, for me, obedience - I want the best odds the puppy I get will have the aptitude to do those things AND it shows the breeder has an interest in creating good dogs.
