so BYB's actually help out a bit in that they keep the gene pool broad.
I guess I don't understand that statement because most BYB's tend to take out of consideration hip/elbows/eyes so even if you're extending the gene pool by allowing other dogs to breed which normally wouldn't, you're still carrying on all of the bad health problems. It seems like kind of a void argument IMO. Unless I'm just not understanding the statement.
I think it also depends on the type of backyard breeder. There are some people who breed dogs as a "hobby" but do health checks/OFA etc. But when I hear BYB I don't think of a person who is responsible.
