For the record, Golden Retrievers and Labradors are NOT couch potatoes either, and the majority of them, of any breeding, are not a good first time dog for a lazy person who doesn't want to do two or three hours a day of exercising with his dog.
I also do agree that if you don't want a working, active sporting or herding dog, then don't get one of these breeds. When I want a lazy dog that sleeps all day and only needs a few sprints a week, I get a Whippet or a Greyhound. There's plenty of lazy sofa hounds in need of homes for people who can't cope with a shedding, high drive, always-ready-to-work retriever or Shepherd.
Even show bred Labs and Goldens need a lot more exercise than a Greyhound or a Pug, and that's as it should be.
The majority of show folks I know in ALL breeds sit ringside and go crazy over a dog they like because "look at that movement!" and "Man, his type is to die for!!!" and working never enters the discussion. That's okay with me- they're playing their game, and they're not stopping me from playing mine. That's what they're breeding for- that's what the market is for.
Also, it doesn't help that even I, who have never set foot in a GSD conformation ring, could tell you who will win at a given show simply by looking at the handlers without even glancing at the dogs. Can we not admit this is part of the problem?
We all pay into and support and own whatever type of dog fits our need, and the game we enjoy playing. Opinions are fine, but at the end of the day I prefer live and let live. It would make me very sad to see the working GSD (or Golden, or Labrador) disappear to be certain, but it won't happen unless the only demand is for pretty movers and extreme type.
The working dogs (which I prefer, by the way, in almost all breeds) are still going strong. There is an ample market for them, too.
I guess I'm saying: breed for whatever you want- but be honest. Admit it
And be responsible for your dogs. That's all I ask.
