So once the cows are out of the barn it is harder to get them back in.

While I do not disagree, there are other methods of clearing stock, but even 
if all that were true, if we do what is right for the breed we must start 
making attempts to first stop the increase (speculating that it really is no 
different than 25 years ago because we did not know much then, I suggest is 
not the mind set to get this accompolished).  Many have concerns of which I 
am in the camp that all this talk deminishes the perceived gravity of the 
problem and lends itself to a relaxation and passive approval to continue 
breeding highly suspect animals.  For example we never relax with Hip 
Dysplasia, why and how can this be any different.  We know dysplasia is here 
to stay, but we use the best tools to combat it.  Now our best tools for 
dwarf control is waiting for a marker (we have no guarantee that anything at 
all will come of this) and being told that all our dogs essentially have a 
50/50 chance of producting at least carriers.  This kind of lends itself to 
two things, 

1.  Lets get out of this breed.  (This may be the best, but might leave those 
who care less or little behind)
2.  What the heck, its always 50%, so lets breed that Best In Show brother of 
a dwarf carrier or producer, to as many bitches as call for stud service and 
plunk down 2K.  We can ethically disclose the 50% chance because essentially 
every other dog (except a few who are test bred properly) in the country has 
the same 50/50 chance.

I suggest if the GPCA choose to look they would see good programs in place by 
other breeds that have merit that would benefit our breed.
