I have many friends who work in shelters and rescue and the reasons people give are just pathetic.
The saddest is those who bought a new puppy so are dumping their senior dog at the shelter.

I could never work there because my people-patience is sorely lacking. Even worse, they are teaching the same attitude to their kids.
Carolinagirl, the problem with those people is that they weren't buying a pet, they were buying a fashion accessory. The same thing happens whenever there is a movie with a dog - bybs rush to fill the sudden market for these dogs. 101 dalmations had dal breeders in tears. People who had no knowledge of the breed, and even worse no desire to learn, wanted a puppy like from the movie. Then comes the rampant health problems from over-breeding, the over-flowing rescues, and the long task of cleaning up the mess.
My GSD forum recently linked an article on the fall of the GSD, celebrating the fact that the breed is falling out of favor with Hollywood and the public. How sad is that, to be excited that people DON'T like your dogs??? The "in thing" with shepherds right now is dark sable, the color of my boy Singe. The biggest problem is that sable is found mostly in working lines. Working line GSDs make good family dogs, don't get me wrong, but they do require a lot of work, training, exercise and patience. Singe can run for hours and still be ready to go, afterall that is the purpose of the breed. And if you don't keep his mind occupied, he will invent his own fun. Throw in a bunch of breeders interested only in color and not knowledgable about temperament and health and you have a disaster in the making.
