This irks me TERRIBLY.
Why are "living room breeders" so proud? Because you produce good dogs?
What about "good" Yorkies? Many of these "living room breeders" produce dogs that carry the Yorkie name, but look NOTHING like them! What gives?
NOTE: I'M NOT SPEAKING FOR ALL LRB, just most of them. Once and a while I'm sure you'll find a diamond in the rough where a LRB has something worth while, but not often.  
 
  
  
I just don't get it.  That'd be like someone w/ a down syndrome child that is proud it has down syndrome because it's "their" child...and keep having children w/o ever getting that child tested BEFORE it's born (even thought they know those tests are available to them!).  Why have dogs the same way? So what if it has a slight problem? It's so sweet and cute, certainly the pups he/she produces must be the same way! ?!?!?
How is that ethical in any way??
-Again, NOT every LRB fits this steriotype, but many do. And YEAH, you'll find people that own Yorkies from LRB that LOVE their dog and the experience they've had w/t he LRB, but most of those people don't know any better anyway and as long as it's cute many of those people don't care (because they don't know all the things they should about Yorkies). 
*grr*
