LisaL - I think what they mean is to continue to breed for specific traits within the specific breed - as in Olde English or American - no any bulldog breeds together or mix breeds, like the so called "designer breeds" Those are mutts - nothing else. Breeding those for the purpose of calling them a designer breed is probably just as bad as the breeding this article is talking about. There are enough dogs in shelters as is without breeding mutts on purpose. Another thing is you cannot guarentee how a dog is going to turn out when they are from two breeds - you cant expect that it is going to keep specific traits from the mother or the fathers breed. There is no guarentee of it and the idea that people would breed mutts so "redesign" a breed is just stupid. You dont add sugar to flour in hopes of making the flour a better flour. Its a sugar/flour mix - nothing else - same with dogs.
