IMo if your dog has a problem in the lines you tell the breeder and the should stop breeding those lines. Or If you are researching lines you can look up the dogs and find there lifespan. With no predigree you are spending the same anyways and may have even worst breeding practices. But yes its still all a gamble I just like to better the odds I would hate to be the 1 or 10 outta 100. But a bad backyard breeder can be 50-60 outta 100..Never know. JMO |
