How do you ever get to the 25% or less if you never use any offspring of a 
known dog carrier or affected?  Also in order to even identify the affected 
dogs, much less the carriers you have to extensively test.  

A lot of common sense must be used here, that combined with vigilance and 
persistence.  Another way to look at it is 50% of offspring are not carriers 
or will not develop the disease.  What in reality we will end up with is only 
BYB, Puppy Mills, and Farm dogs being bred.  Don't think that is what this is 
all about.  I do not recommend breeding any known carrier or affected dog.  I 
recommend that any offspring that have a chance of being either are checked 
very carefully and insist that all mating partners under go the same level of 
scrutiny.  This will not be perfect but will result in a much better scenario 
and eventual control of the condition.  Much better, IMHO, than ignoring the 
problems, impugning those who are working openly, and quibbling about what is 
important and what should be ignored or not.
