This is a bit OT, but it really is similar to the rescue groups that purchase from auction.
I don't like it. They're helping to feed their coffers. They need to let these dogs go to shelters and pet stores. Instead of attending auctions, they need to take a trip down to their local shelter - there's plenty there I'm sure. The pet stores are going to find dogs regardless - it's simple supply and demand. If not from the mills, they'll get them from BYB's. They're not going to stop it. Similarly, the dogs that usually end up on auction would have never made it to pet stores to begin with. The dogs at auction are usually breeding animals, which would have likely ended up either euthanized or at a shelter after the millers were done with them anyway.
I hate to say it, but part of me thinks that many of these organizations find that these extreme cases create sensationalism, which tugs on the average person's heart strings which helps to drive support and donations. It's kinda sad when you think that one dog that is in rescue for 6 mos to a year overcoming various maladies is causing many other healthy, adoptable dogs to languish at shelters.
I firmly believe that rescues should concentrate on owner surrenders and shelter pulls and that rescues need to be selective when making decisions as to which dogs come in and which dogs don't. Obviously, it's not a good use of the rescue's money to take in a 11 year old that is in need of chemo and has a rotten mouth and a broken leg because of a hit-by-car. It may sound sad and cold, but again, how many dogs perish at the cost of saving the one that (really) can't be saved?
